V. – 7. VI., DASHENNONGJIA mts., 31.5 N 110.3 E, 2700 m, Jaroslav Turna leg., 2005. ” (CRS) . Paratypes (a total of 4 ♀): Hubei • 2 ♀, the same data as holotype (CRS); • 2 ♀, labeled “ Hubei Province, Shennongjia, Jinhouling, 2500 m, pitfall trap, 2013. VIII. 15, Hao Huang leg. ” [in Chinese] (IZAS) .</p><p>Diagnosis.</p><p>Very small-sized species for the subgenus (BL = 4.6–4.7 mm), the smallest known Pterostichus species in China; elytra with linear microsculpture in females; antennae moniliform, antennomere 3 with accessory on apical half; pronotum slightly cordate, maximum width near apical third; basal foveae finely punctate, with faintly defined sulci; parascutellar pore absent; elytral interval 3 with three setigerous pores, the basal one adjacent to stria 3, the other two adjacent to stria 2; interval 1 with one setigerous pore near apex, adjacent to stria 1; fifth tarsomeres with two pairs of setae ventrally.</p><p>Comparisons.</p><p>The new species, P. chachi sp. nov., is very special within the subgenus Morphohaptoderus and different from all other known species of the subgenus by the following distinctive characteristics: (1) Body size very small, BL = 4.6–4.7 mm, being the smallest species of the subgenus as well as the smallest one of Pterostichus from China; (2) elytra without parascutellar pore (Fig. 4 G); (3) interval 3 with three setigerous pores, the first adjacent to stria 3, the other two adjacent to stria 2 (Fig. 26 A); (4) interval 1 with one setigerous pore near apex (Fig. 26 B, C).</p><p>Most of the above-mentioned characteristics are either unique or relatively rare within the subgenus Morphohaptoderus, with the details elaborated as follows. The previously known smallest Pterostichus species in China was P. gongga Sciaky, 1997, with a measured BL of 4.8–5.9 mm, which also belongs to the subgenus Morphohaptoderus . Besides P. chachi sp. nov., the parascutellar pore is absent only in two Morphohaptoderus species from Vietnam, P. unisetosus Fedorenko, 2023, and P. glabellus Fedorenko, 2023 . Only two other species, P. toledanoi and P. xuanzhang sp. nov., both from Hubei, share a chaetotaxy on elytral interval 3 similar to that of the present new species. However, in these two species, the three setigerous pores on interval 3 are positioned relatively more posteriorly. Specifically, they are located at the basal fourth, near the middle, and the apical fourth, respectively. In contrast, in P. chachi sp. nov., these pores are more anteriorly placed, at the basal fifth, basal two-fifths, and apical third, respectively. Finally, the presence of a setigerous pore on interval 1 (Fig. 26 B, C) is unique to P. chachi sp. nov. and has never been observed in any other Pterostichus species in China.</p><p>The general habitus of the new species P. chachi sp. nov. is somewhat similar to some small-sized Morphohaptoderus from Western China, such as P. confucius Sciaky &amp; Wrase, 1997, P. gongga Sciaky, 1997, and P. emei Sciaky, 1994 . But different from them by the smaller body size, distinctive chaetotaxy on elytra, and submentum with one seta on each side.</p><p>Description.</p><p>BL = 4.6–4.7 mm, BW = 1.7–1.8 mm; dorsal surface brown to dark brown, elytra slightly lighter than head and pronotum, appendages brown; elytra with linear microsculpture in females (Fig. 26 A).</p><p>Head slightly thickened, HW / PW = 0.62–0.64; frons without puncture; frontal sulci short and shallow; antennae moniliform, reaching elytral basal fourth, antennomere 3 with a few accessory setae on the entire surface of apical half; eyes relatively small, the length of tempora slightly shorter than the length of eyes; submentum with one seta on each side.</p><p>Pronotum slightly cordate, wider than length, PW / PL = 1.30–1.31, widest near apical third, posterior margin much narrower than greatest width, PBW / PW = 0.78–0.80. Anterior margin concave at middle, slightly narrower than posterior margin, PAW / PBW = 0.85–0.86; anterior angles broadly rounded, weakly projecting; lateral margins evenly arched nearly along their full length, more distinctly narrowed toward base, not sinuate before posterior angles, posterior angles obtuse-angled, with very faint denticle not projecting out. Basal foveae (Fig. 4 G) shallow and finely punctate, punctures along inner and outer sulci, as well as on intersulcate area; inner and outer sulci without well-defined boundaries; inner sulcus straight and shallow, outer sulcus very faint, hardly recognizable; a basal sulcus fine but clearly defined, long and straight, medially extending beyond the base of inner sulcus, shortly bent to the front laterally, surrounding the inner side of the setigerous pore on posterior angle; intersulcate area slightly convex; lateral channels narrow, without puncture. Pronotal disc with very faint transverse wrinkles aside median line; median line shallow; basal median area with a few punctures close to inner sulcus.</p><p>Elytra oval and flat, humeral area distinctly narrowed, lateral sides curved and expanded near middle, BW / EL = 0.68–0.69. Elytral basal border nearly straight, forming a distinct obtuse angle with lateral margin, humeral tooth small, apex faintly pointed; striae without punctures, slightly crenulate on basal third; parascutellar striole joined to apical portion of stria 1, angular base of stria 1 absent or indicated by one or two isolated punctures. Parascutellar pore absent (Fig. 4 G); elytral interval 3 with three setigerous pores, the first pore adjacent to stria 3, positioned near basal fifth, the other two pores adjacent to stria 2, near basal two-fifths and apical third respectively; interval 1 with one setigerous pore near apical sixth, adjacent to stria 1 (Fig. 26 B, C); umbilical pore series on ninth interval sparse in middle, composed of 12–14 pores (5–6, 1–2, 6–7). Elytral apical margin shortly truncated, faintly denticulate at sutural angles (Fig. 26 F).</p><p>Fifth tarsomeres with two pairs of fine setae ventrally.</p><p>Male sternite without secondary sexual modification, apex of sternite VII evenly rounded.</p><p>Median lobe of aedeagus (Fig. 26 B) relatively slender; in lateral view, ventral margin bent near basal fourth, nearly straight at middle portion before apical fourth, slightly sinuate at apical fourth, apex distinctly bent to the ventral side; apical orifice relatively small, weakly turned to left side, opened to the dorsal left surface of median lobe. Ventral surface without ridge. Apical lamella thin in lateral view; narrow and relatively long in dorsal view (AL / AW = 1.56), faintly turned to left side, gradually narrowed to apex, shaped a narrow triangle, apex rounded (Fig. 26 C); lamellar denticle very small and faint, present near basal third of left margin. Right paramere short, apex rounded and extremely small (Fig. 26 D).</p><p>Endophallus of male genitalia not studied due to restricted materials.</p><p>Gonocoxite 2 of female ovipositor small, widely crescent-shaped (Fig. 5 M), slightly obtuse apically; outer margin with two or three ensiform setae of normal size, length of the largest ensiform seta ca. 0.03 mm; dorsal margin with one ensiform seta near middle, ridged between the ensiform seta and apex of gonocoxite 2, one nematiform seta located on the apical fifth of outer surface.</p><p>Distribution.</p><p>This species is only known from Jinhouling in Shennongjia, Hubei Province. It is distributed at a high altitude of about 2500 m.</p><p>Etymology.</p><p>The scientific name of the new species is derived from Qu Yuan’s work “ Ai Ying ”: 惨郁郁而不通兮 [Can Yu Yu Er Bu Tong Xi], 蹇侘傺而含戚 [Jian Cha Chi Er Han Qi]. This couplet can be translated as: My mood is heavy with melancholy. I stand alone, filled with sorrow. It describes the poet’s sorrowful mood after the fall of the capital of Chu and the humiliation of King Chu by the people of Qin. Chachi (侘傺) describes a scene of standing alone in dejection in the poem. As a specific name, chachi implies that the new species is very rare, with only one sex having been discovered. The name is treated as a noun in apposition.</p></div>	https://treatment.plazi.org/id/BB28BA3B958B54458D7A490593DE77BB	Public Domain	No known copyright restrictions apply.

The males can be readily distinguished from other similar species from Hubei by the unique sexual character on sternite VI (Fig. 2 A, D) and females by elytra with linear microsculpture (Fig. 6 F).</p><p>Compared with related species from other provinces, P. dentellus is most similar to P. chungkingi Jedlička, 1932 and P. guizhouensis Sciaky, 1997 for the females without granular microsculpture, pronotum distinctly constricted to base and antennomere 3 without accessory setae. But it can be recognized from these species by the pronotum narrower and less punctate on basal fovea; median lobe of male genitalia much slenderer with larger apical lamella (Fig. 12 A – C); and the gonocoxite 2 of ovipositor with three or more ensiform setae on outer margin (Fig. 5 A).</p><p>Description.</p><p>This species is easily recognizable and has been sufficiently described by Facchini and Sciaky (2003). A redescription is unnecessary here, except for the following supplementary descriptions on the endophallus (Fig. 7 A, B): Endophallus helicon-shaped, extending to the apical direction of aedeagus, major parts of endophallus located on dorsal-left side of aedeagus; gonopore opened to lateral-basal direction of aedeagus; surface with fine scales, densest near gonopore; gonoporal piece small. Ventral side of endophallus compressed and pigmented, with a chitinized piece. Two distinct lobes recognized: left pre-apical lobe (lp) relatively large and rounded, close to base of apical lamella, decorated with fine scales, visible in both lateral views; left apical lobe (la) small and rounded, just before gonopore and close to apex of apical lamella, decorated with very fine scales.</p><p>Distribution.</p><p>This species is known from three distant localities: Shennongjia in Hubei and Chengkou and Wuxi in Chongqing, all distributed at relatively high altitudes of 1700–2500 m.</p></div>	https://treatment.plazi.org/id/1814CB2348C45A89BFA4B61D08F27C97	Public Domain	No known copyright restrictions apply.

Apical lamella of aedeagus elongated triangular, longer than basal width.</p><p>Comparisons.</p><p>The present new species, P. lianquan sp. nov., is most closely related to the following species, P. zhizheng sp. nov. These two new species are different from all other Morphohaptoderus species in China by the elytra with only one setigerous pore, and median lobe of aedeagus without ventral ridge, apical lamella not toothed or denticulate. In this aspect, these two new species are only similar to P. unisetosus Fedorenko, 2023, from North Vietnam. However, P. unisetosus is different from them by the elytra without parascutellar pore, submentum with two setae on each side, median lobe of aedeagus much stouter with shorter apical lamella.</p><p>Despite the aforementioned similarities in key characteristics, these two new species have the following distinct differences in external appearances and male genitalia: (1) In P. lianquan sp. nov., pronotum very strongly constricted at base, PBW / PW = 0.63–0.67 (Fig. 5 K); whereas in P. zhizheng sp. nov., pronotum only weakly constricted at base, PBW / PW = 0.75–0.77 (Fig. 5 L). (2) In P. lianquan sp. nov., pronotum coarsely and widely punctate on the basal fovea and basal-median area; but only with fine punctures along the inner sulcus in P. zhizheng sp. nov. (3) Elytral basal border entirely straight in P. lianquan sp. nov., but distinctly curved in P. zhizheng sp. nov. (4) In P. lianquan sp. nov., the apical lamella of aedeagus strongly elongate and attenuate apically, with the length of apical lamella distinctly greater than its basal width (Fig. 21 B); conversely, in P. zhizheng sp. nov., the apical lamella shorter and wider, length less than its basal width (Fig. 22 B).</p><p>These two species also have the fifth tarsomere asetose ventrally, and this characteristic is relatively uncommon within the subgenus. Prior to this study, among Chinese species, only P. geberti Sciaky &amp; Wrase, 1997, which was discovered in Shaanxi, was known to lack the ventral setae on the fifth tarsomeres. However, we do not consider P. geberti to be related to the two new species described here, because P. geberti has two setae on each side of the submentum, two setigerous pores on elytral interval 3, and the apical lamella of its aedeagus toothed on the right margin.</p><p>Description.</p><p>BL = 8.8–9.6 mm, BW = 3.2–3.6 mm; dorsal surface dark brown to black, appendages brown; elytra with linear microsculpture in both sexes (Fig. 21 D, E).</p><p>Head slightly thickened, HW / PW = 0.57–0.59; frons without puncture; frontal sulci short and shallow; antennae reaching elytral basal fifth, antennomere 3 without accessory seta; eyes large and hemispherical, tempora very shortly swollen behind eyes; submentum with one seta on each side.</p><p>Pronotum nearly circular, slightly wider than length, PW / PL = 1.12–1.16, widest near middle, PBW / PW = 0.63–0.69.

These two species only have inconspicuous external differences which explicated as follows: (1) P. lingjun sp. nov. generally has a slightly larger body size; (2) the area between lateral channel and outer sulcus usually more distinctly punctate in P. quyuani sp. nov. (Fig. 3 E); (3) in P. lingjun sp. nov., the first discal pore on elytral interval 3 positioned relatively more towards the posterior. In the only two known specimens of P. lingjun sp. nov., the index of the first discal pore on elytral interval 3 is between 0.42 and 0.48 (derived from the ratio of the distance between elytral base and the first discal pore to EL), and this index is usually from 0.30 to 0.36 in P. quyuani sp. nov. However, because P. quyuani sp. nov. is a relatively common species, there are a few exceptional specimens in which this index approximates to that of P. lingjun sp. nov.</p><p>Although these two species have a striking external similarity, the characters on male sternite VII and aedeagus are distinct between them: (1) in P. quyuani sp. nov., the male sternite VII are distinctly wrinkled on left-posterior side (Fig. 2 B), but without wrinkles in P. lingjun sp. nov. (Fig. 2 F); (2) in the aedeagus of P. quyuani sp. nov., the lamellar denticle is particular large, nearly twice as long as the lamellar apex (Fig. 12 F – I); in contrast, in P. lingjun sp. nov., the lamellar denticle is much smaller than the lamellar apex (Fig. 12 J); (3) in P. quyuani sp. nov., the ventral surface of median lobe of aedeagus with a strong ridge that sinuate and extends to base (Fig. 8 C); but in P. lingjun sp. nov., this ridge is much shallower, straight and disappeared before base (Fig. 15 C). Although the above distinct differences exist for males, the females of these two species are very difficult to differentiate. The most reliable way to distinguish the females between these two species may merely be the altitude at which the specimens were collected. P. lingjun sp. nov. was only found in Guanmenshan of Shennongjia at the altitude of about 1361 m, but all specimens of P. quyuani sp. nov. were collected at the altitude above 1600 m.</p><p>P. lingjun sp. nov. is also similar to P. lisao sp. nov. for their male sternite VII depressed without wrinkles and median lobe of aedeagus relatively stout. These two species are different in the following aspects: (1) in P. lisao sp. nov., the outer sulcus of pronotal basal fovea strongly reduced, less than one-third length of inner one (Fig. 3 D); whereas in P. lingjun sp. nov., the outer sulcus is normal as other species, about half length of the inner one (Fig. 3 E); (2) in P. lingjun sp. nov., the male sternite VII more widely depressed, the depression with a branch extending to the basal-left side of the sternite (see the white arrow in Fig. 2 F); but the basal-left side not depressed in P. lisao sp. nov. (Fig. 2 E); (3) in the aedeagus of P. lingjun sp. nov., the lamellar denticle smaller, in lateral view much shorter than the lamellar apex (Fig. 12 J); whereas in P. lisao sp. nov., lamellar denticle larger, about in same length of lamellar apex (Fig. 13 A – E); (4) in P. lisao sp. nov., the lamellar denticle forming a distinct angle (about 110 °) with lamellar apex, but in P. lingjun sp. nov., these two structures almost collinear; (5) in the median lobe of aedeagus of P. lingjun sp. nov., the ventral surface only with one short ridge before apical orifice (Fig. 15 C), but with three ridges in P. lisao sp. nov. (Fig. 14 C).</p><p>P. lingjun sp. nov. is also similar to P. shennongjianus and P. wangshu sp. nov., all distributed in Shennongjia. The present new species is different from P. shennongjianus for the elytral interval 3 with only two setigerous pores; the area between lateral channel and outer sulcus less convex; male sternite VII more distinctly depressed.

Specifically, the outer sulcus is highly reduced, typically presenting as a large, elongated puncture (Fig. 3 D). In some specimens, although the outer sulcus is somewhat more developed, its apex can extend to near the midpoint of the inner sulcus, and its base is clearly separated from the basal margin of the pronotum. As a result, the length of the outer sulcus is less than one-third of the inner sulcus.

Median lobe of aedeagus with a sinuate ventral ridge; lamellar denticle large, nearly twice length of lamellar apex. Gonocoxite 2 of ovipositor crescent-shaped, dorsal margin ridged on apical half, outer margin with two or three ensiform setae of normal size.</p><p>Comparison. The new species, P. quyuani sp. nov., is externally very similar to P. shennongjianus Facchini &amp; Sciaky. These two species are sympatric and have often been confused with each other. Generally, they present the following differences in external characters: (1) In P. quyuani sp. nov., the region between the pronotal lateral channel and the outer sulcus of the basal fovea is typically less convex, forming a shallower ridge (Fig. 3 B). The outer surface of this ridge usually has a few fine punctures; in contrast, in P. shennongjianus this area is usually more convex, forming a more prominent ridge, and the surface of the ridge is usually impunctate (Fig. 3 C). (2) In P. quyuani sp. nov., the pronotal lateral channels are usually wider and finely punctate along their entire length. Conversely, in P. shennongjianus, the lateral channels are slightly narrower and at most punctate only behind the middle. (3) In P. quyuani sp. nov., elytral interval 3 usually has two setigerous pores, whereas, in P. shennongjianus, it usually has three or four pores.</p><p>However, the external characters mentioned above can sometimes vary individually. In fact, it is extremely difficult to distinguish these two species (as well as the other two new species described herein, P. lisao sp. nov. and P. lingjun sp. nov.) based only on external features. Nevertheless, they can be reliably differentiated by the stable characteristics of male sternite VII, male genitalia, and gonocoxite 2 of the ovipositor.</p><p>The male sternite VII of P. quyuani sp. nov. is shallowly depressed. There are shallow oblique wrinkles on the left side of this depression, and the apex of sternite is slightly truncated (Fig. 2 B). Conversely, the male sternite VII of P. shennongjianus has a much fainter depression, lacks wrinkles, and the apex of sternite is more rounded (Fig. 2 C). Compared to all other similar species from Hubei, the presence of wrinkles on the male sternite VII is a characteristic exclusive to P. quyuani sp. nov. (Fig. 2).</p><p>Regarding the male genitalia, in P. quyuani sp. nov., the median lobe is very stout (Fig. 8 B). On its ventral surface, there is a sinuate short ridge that extends from the middle of the aedeagal base to the right margin and then terminates at the left margin (Fig. 8 C). In contrast, in P. shennongjianus, the median lobe is more slender (Fig. 10 B) and has a straight short ridge on the left margin of the ventral surface (Fig. 10 C). Furthermore, when considering the apical lamella of the aedeagus, in P. quyuani sp. nov., the lamellar denticle is very large, being nearly twice as long as the lamellar apex (Fig. 12 F – I). However, in P. shennongjianus, the lamellar denticle is smaller and approximately equal in length to the lamellar apex (Fig. 13 F – J).</p><p>For the female ovipositor, in P. quyuani sp. nov., gonocoxite 2 shows the typical form of the subgenus: strongly curved, with a sharp apex, dorsal ridge absent on basal half, and ensiform setae large (Fig. 5 C). But in P. shennongjianus, gonocoxite 2 has a distinct form: nearly straight, with an obtuse apex, dorsal ridge almost reaching base of gonocoxite 2, and ensiform setae minute (Fig. 5 B).</p><p>The newly described species P. quyuani also strongly resembles three other new species within the maximus group: P. lingjun sp. nov., P. lisao sp. nov., and P. wangshu sp. nov. Their comparison will be presented in the descriptions of those new species. When compared to species from other provinces, P. quyuani sp. nov. is most similar to P. lingshanus Sciaky &amp; Wrase, 1997 from Shaanxi province, since both share characteristics such as the granular microsculpture in females, antennomeres 3 without accessory setae, and the pronotum not strongly constricted towards the base. However, P. lingshanus differs from the present new species in several ways: size generally smaller, male sternite VII not wrinkled, and lamellar denticle of the male genitalia much smaller, shorter than the lamellar apex when in lateral view. Regarding the depressed and wrinkled male sternite VII, the present species may also be related to P. maximus Tschitschérine, 1889, from Gansu, and P. dundai Sciaky, 1994, from Shaanxi. Nevertheless, compared to P. quyuani sp. nov., P. maximus is easily distinguishable by its elytral striae distinctly punctate and the male sternite VII more strongly wrinkled. P. dundai, on the other hand, differs in its pronotum more constricted towards base, male sternite VII depressed but not wrinkled, and the apex of the right paramere of male genitalia strongly elongated.</p><p>Description.</p><p>BL = 9.3–11.3 mm, BW = 3.7–4.5 mm; dorsal surface dark brown to black, appendages brown; elytral microsculpture linear in males, granular in females (Fig. 8 F, G).</p><p>Head slightly thickened, HW / PW = 0.54–0.57; frons without puncture; frontal sulci short and shallow; antennae reaching elytral basal fifth, antennomere 3 without accessory seta; eyes large and hemispherical, tempora very shortly swollen behind eyes; submentum with one seta on each side.</p><p>Pronotum rounded-rectangular, wider than length, PW / PL = 1.32–1.45, widest near middle, PBW / PW = 0.75–0.79.

Parascutellar pore present; elytral interval 3 usually with two setigerous pores, sometimes with three, on one or both sides (among the examined 98 specimens, eight showed three pores on one elytron and six showed three pores on both elytra), all pores adjacent to stria 2; umbilical pore series on ninth interval sparse in middle, composed of 16–18 pores (6–7, 2–3, 8–9).</p><p>Fifth tarsomeres with 3–5 (usually 4) pairs of setae ventrally.</p><p>Male sternite VI not modified; sternite VII asymmetrically depressed at middle, middle depression large and shallow, with oblique wrinkles on the posterior portion of the left side of the abdomen in dorsal view; with strong isodiametric microsculpture on center of the depression, gradually turned to shallower and transverse microsculpture to lateral and anterior regions; apex of sternite slightly truncated (Fig. 2 B).</p><p>Median lobe of aedeagus (Fig. 8 B) stout; in lateral view, ventral margin evenly curved at middle portion, nearly straight before apical lamella and then slightly bent ventrally; apical orifice opened to left-dorsal surface of aedeagus. Ventral surface with a strong sinuate ridge before apical orifice (Fig. 8 C): right ridge absent; median ridge absent; left ridge sharp, strongly sinuate near base, extended from middle part of aedeagal base to right margin, and then bent to the left, ending at left margin of the base of apical orifice. Apical lamella large and thick (Fig. 8 A), rounded in dorsal view, apex widely rounded; with very large lamellar denticle near base of left margin; in lateral view, lamellar base and apex both short, lamellar denticle large, nearly twice length of lamellar apex (laL / ldL = 0.59–0.61), collinear with lamellar apex. Right paramere short, apex rounded (Fig. 8 E).</p><p>Endophallus (Fig. 7 C, D) bent to ventral side across left margin of aedeagus, major parts of endophallus located on ventral side of aedeagus; gonopore opened to ventral-apical direction of aedeagus; surface with coarse scales on expanded lobes, densest near gonopore; gonoporal piece large, falciform. Four distinct lobes recognized: basal lobe (bl) small, located near base of apical orifice, membranous without decoration; left pre-apical lobe (lp) very large, located in left surface near apical lamella, decorated with fine scales, visible in the right lateral view; left apical lobe (la) large and rounded, adjacent to basal lobe, with coarse scales on apex, visible in both lateral views; right apical lobe (ra) rounded, apex with digitiform protuberance, visible in the left lateral view, apex of the protuberance scaled.</p><p>Gonocoxite 2 of female ovipositor crescent-shaped (Fig. 5 C), sharply pointed apically; outer margin with two or three ensiform setae of normal size, length of the largest ensiform seta ca. 0.07 mm, dorsal margin with one or two ensiform setae before middle, strongly ridged from the distal ensiform seta to apex of gonocoxite 2, one nematiform seta located on the apical fifth of outer surface.</p><p>Distribution.</p><p>This species is known from two distant localities: Shennongjia in Hubei and Wuxi in Chongqing. Most specimens were collected at a middle-high altitude ranging from 1600 m to 2300 m (only one specimen was collected at 3090 m and two specimens were collected at 2500 m). This species is the most common species of subgenus Morphohaptoderus in Shennongjia.</p><p>Etymology.</p><p>The new species is named after Qu Yuan (屈原), a renowned poet and statesman in ancient China who lived in the State of Chu (centered around today’s Hubei Province) during the Warring States Period. His works, like “ Li Sao, ” shaped Chu Ci (also known as Songs of Chu, a significant genre in ancient Chinese literature). To commemorate Qu Yuan and promote the culture of Chu, the scientific names of all new species discovered in Hubei Province hereinafter are derived from Qu Yuan’s poems. The specific epithet is a genitive noun.</p><p>Remarks. We examined one paratype of P. shennongjianus (Fig. 9 B, C). Based on the punctures lateral to the outer sulcus of the pronotal basal fovea and the shape of the male genitalia, this specimen is identical to the present new species but differs from the holotype of P. shennongjianus (habitus Fig. 9 A; male genitalia illustrated in Facchini and Sciaky 2003: 12).</p></div>	https://treatment.plazi.org/id/27DCEAF8E3A25697A0064F8C6A9A0643	Public Domain	No known copyright restrictions apply.

It is characterized by the absence of ventral setae on the fifth tarsomeres and the presence of two setigerous pores on elytral interval 3, both of which are adjacent to stria 2. In this regard, the present new species resembles only P. yaotiao sp. nov. However, the two species differ substantially in terms of body size, overall habitus, and male genitalia. Specifically, P. yaotiao sp. nov. has a significantly larger body (BL = 7.9–10.0 mm), a more elongate body form with nearly parallel lateral margins, and the median lobe of aedeagus features a ventral ridge and lamellar denticles.</p><p>Actually, among all other Chinese species within the subgenus Morphohaptoderus that possess two setigerous pores on elytral interval 3 adjacent to stria 2, the male genitalia exhibit a particular form. Specifically, the ventral surface of the median lobe has a ridge, and the apical lamella has lamellar denticle on its left surface. In this regard, P. rongyu sp. nov. is very special within the subgenus.</p><p>Although they have similar elytral chaetotaxy, we do not consider P. rongyu sp. nov. to be related to P. yaotiao sp. nov. due to their markedly different male genitalia. Instead, we suspect a relationship between P. rongyu sp. nov. and P. zhizheng sp. nov. as well as P. lianquan sp. nov., even though the latter two species have only one setigerous pore on elytral interval 3. All three of these mentioned species share a relatively simple form of the median lobe of aedeagus, lacking a ventral ridge or apical lamellar denticle. However, P. zhizheng sp. nov. and P. lianquan sp. nov. can be easily distinguished from P. rongyu sp. nov. by their much larger body size, more elongated body form, the presence of only one setigerous pore on interval 3, and the longer apical lamella of the aedeagus.</p><p>Description.</p><p>BL = 5.7–6.1 mm, BW = 2.4–2.7 mm; dorsal surface dark brown to black, appendages brown; elytra with linear microsculpture in both sexes (Fig. 25 D, E).</p><p>Head slightly thickened, HW / PW = 0.56–0.59; frons without puncture; frontal sulci deep and straight, extended near to the anterior supraorbital seta; antennae filiform, reaching elytral basal sixth, antennomere 3 without accessory seta; eyes large and hemispherical, tempora very shortly swollen behind eyes; submentum with one seta on each side.</p><p>Pronotum rounded-rectangular, distinctly wider than length, PW / PL = 1.34–1.35, widest a little before middle, posterior margin much narrower than greatest width, PBW / PW = 0.82–0.84. Anterior margin shallowly concaved at middle, slightly narrower than posterior margin, PAW / PBW = 0.71–0.74; anterior broadly rounded, weakly projecting; lateral margins evenly arched before middle, distinctly narrowed and nearly straight along posterior half, not sinuate before posterior angles, posterior angles nearly right-angled, with a small denticle slightly projecting out. Basal foveae (Fig. 4 H) with coarse and sparse punctures along inner and outer sulcus, as well as on base of intersulcate area; inner sulcus shallow with distinct boundary, slightly oblique to pronotum basal margin, base ending before pronotum basal margin; outer sulcus very faintly indicated, only represented by a few gathered punctures; a short and shallow basal sulcus usually present, medially not extending to the base of inner sulcus; intersulcate area flat; area between lateral margin and outer sulcus flat; lateral channels narrow, with very faint punctures. Pronotal disc without wrinkles aside median line; median line shallow.</p><p>Elytra oval and slightly convex, lateral sides distinctly expanded behind middle, BW / EL = 0.74–0.75. Elytral basal border slightly curved, forming an obtuse angle with lateral margin, humeral tooth small, apex faintly pointed; striae punctate on basal third; parascutellar striole joined to apical portion of stria 1, angular base of stria 1 absent (Fig. 4 H). Parascutellar pore present; interval 3 with two setigerous pores, both adjacent to stria 2, first setigerous pore positioned near middle, the rest one near apical third; umbilical pore series on ninth interval sparse in middle, composed of 13–14 pores (5–6, 1–2, 6–7).</p><p>Fifth tarsomeres without seta ventrally.</p><p>Male sternite without secondary sexual modification, apex of sternite VII evenly rounded.</p><p>Median lobe of aedeagus (Fig. 25 A) relatively slender in lateral view, ventral margin evenly curved along all the full length, apex weakly bent to the ventral side; apical orifice wide and short, weakly turned to left side, opened to the dorsal left surface of median lobe. Ventral surface without ridge. Apical lamella thin in lateral view; short and wide in dorsal view (AL / AW = 0.69–0.71), faintly turned to left side, gradually narrowed to apex, shaped a wide triangle, apex widely rounded, without denticle or tooth (Fig. 25 B). Right paramere short, apex rounded (Fig. 25 C).</p><p>Endophallus of male genitalia not studied due to restricted materials.</p><p>Gonocoxite 2 of female ovipositor small, widely crescent-shaped (Fig. 5 N), sharp apically; outer margin with two ensiform setae in large size, length of the largest ensiform seta ca. 0.04 mm; dorsal margin with one ensiform seta near apical third, ridged between the ensiform seta and apex of gonocoxite 2, one nematiform seta located on the apical seventh of outer surface.</p><p>Distribution.</p><p>The new species is known by two specimens collected from Shennongjia in Hubei Province and Wuxi County in Chongqing Municipality. These two collection sites are adjacent to each other, with a linear distance of about 50 km between them. The altitude of this species is relatively low, ranging from 1361 m to 1467 m.</p><p>Etymology.</p><p>The scientific name of the new species is derived from Qu Yuan’s work “ Xiang Fu Ren ”: 时不可兮骤得 [Shi Bu Ke Xi Zhou De], 聊逍遥兮容与 [Liao Xiao Yao Xi Rong Yu]. This couplet can be translated as: The wonderful moments have passed, never to return. Let me roam at ease, with a leisurely air. Rongyu (容与) is a term used to depict a carefree scene in the poem. The name rongyu is proper for a Pterostichus species because these beetles are often seen running freely in the forest. The name is treated as a noun in apposition.</p></div>	https://treatment.plazi.org/id/E01713ABC2AA542B9045BD7B3D4CB1A1	Public Domain	No known copyright restrictions apply.

Sciaky, 1994: 1.</p><p>Diagnosis.</p><p>Species of the subgenus Morphohaptoderus can be recognized among the Chinese and Southeast Asia Pterostichus by the following combination of characters: body relatively short and wide; elytra elliptic and depressed, not parallel-sided, surface usually iridescent or shagreened (only in females); dorsum dark reddish brown to black; basal foveae of pronotum usually with distinct inner and outer sulci; metacoxae with three setae; fifth tarsomeres usually setose ventrally; metepisternum not longer than wide; right paramere very short, apex rounded (except for Pterostichus dundai Sciaky, 1994); apex of aedeagus often hooked or denticulate.</p><p>Subgeneric characters.</p><p>Small to medium-sized Pterostichus (4.6–12.6 mm); elytra elliptic, slightly arcuate laterally, not parallel-sided; dorsum dark reddish brown to black; males usually with linear microsculpture (Fig. 1 H) on elytra, often forming iridescent luster; females sometimes with matte elytra formed by granular microsculpture (Fig. 1 I). Head relatively small to slightly thickened, always narrower than pronotum; submentum with one or two setae on each side; antennae reaching or slightly exceeding elytral base, antennomere 3 with a few long primary setae forming an apical ring (Fig. 1 B), sometimes also with short accessory setae along inner margin (Fig. 1 A). Pronotum various in shape, mostly nearly circular; posterior angles often distinct but highly variable across different species; basal foveae shallow, usually forming distinct inner and outer sulci, with area between lateral margin and outer sulcus often relatively flat and not ridged. Elytra flat and oblong, striae usually relatively deep; parascutellar stria absent or present; elytral humerus usually with a tooth; interval 3 often with one to five setigerous pores but without setigerous pores in P. glabellus Fedorenko, 2023, and some undescribed species from China. Length of metepisternum approximately equal to its basal width. Sternite VII with one seta on each side in males and two in females; male sternite VI or VII usually without secondary sexual modification, seldom with shallow depression or wrinkles (Fig. 2). Metacoxae with three setae, the medial-posterior seta present (Shi and Liang 2015: fig. 137); metatrochanters with a seta; fifth tarsomeres often setose ventrally (Fig. 1 F – G), asetose in some species from eastern China and Vietnam (Fig. 1 E). Apical orifice of aedeagus deviated to left; shape of apical lamella variable among different species, often hooked, denticulate, or twisted; right paramere very short, apex rounded (except for P. dundai Sciaky, 1994). Gonocoxite 2 of female ovipositor falciform, outer margin with two to four ensiform setae, dorsal margin with one to three ensiform setae, ridged distal to the seta.</p><p>Recognitions among Chinese subgenera of Pterostichus .</p><p>In most Chinese subgenera of Pterostichus, the metacoxa bears two lateral setae: one close to the posterior angle and the other to the anterior margin (setae 1 and 2 in Shi and Liang 2015: fig. 137). However, four Chinese subgenera possess an additional seta near the medial angle (seta 3 in Shi and Liang 2015: fig. 137): Tschitscherinea Berg, 1898, Morphohaptoderus Tschitschérine, 1898, Cryobius Chaudoir, 1838, and Huaius Tian &amp; Huang, 2019 . Based on this synapomorphy and phenetic similarities, these four subgenera are hypothesized to be more closely related to each other than to other subgenera in the Chinese fauna. Among them, members of Morphohaptoderus can generally be recognized by their relatively stout body form and the very short right paramere of the male genitalia. Nevertheless, these diagnostic characters are not universally applicable to all species of the subgenus, suggesting that the group may not be monophyletic. Detailed comparisons among Morphohaptoderus, Tschitscherinea, and their relatives were provided in our previous study (Yin et al. 2024).</p><p>After examining the type specimens of two species, P. megaloderus Sciaky, 1994, and P. yulongshanensis Sciaky, 1997 (Fig. 30 A, B), which were previously assigned to the subgenus Morphohaptoderus, it was found that they do not conform to this subgenus in terms of two key characteristics: the metacoxae with only two setae, with the medial seta absent (Fig. 30 F); and the apex of the right paramere slightly pointed (Fig. 30 E). These characteristics, together with the general features of their habitus and male genitalia, indicate that these two species are closely related to some members of the subgenus Neohaptoderus, such as P. berezowskii Tschitschérine, 1898 . Therefore, the following new subgeneric assignments are proposed herein: P. (Neohaptoderus) megaloderus and P. (Neohaptoderus) yulongshanensis . Thus, prior to the present study, the subgenus Morphohaptoderus comprised 34 species.</p><p>Distribution and diversity.</p><p>Including the ten new species described in this study, the subgenus Morphohaptoderus now comprises a total of 44 species. Most of them (40 species) are endemic to China, distributed across Yunnan, Sichuan, Shaanxi, Gansu, Guizhou, Hubei, and Chongqing provinces, with an exceptionally high species richness in Sichuan, Shaanxi, and Hubei. Additionally, three species are distributed in northern Vietnam (Fedorenko 2023), and one species occurs in northern Myanmar (Wrase and Schmidt 2006).</p><p>In Sichuan and Yunnan, species of Morphohaptoderus generally inhabit cloud forests at relatively high altitudes, ranging from approximately 3000 to 4000 m. In eastern provinces such as Hubei and Chongqing, some species occur at lower altitudes, even below 1000 m. Based on our examined specimens, numerous new species await description.</p><p>Taxonomical notes.</p><p>Prior to the present research, we had studied all described species of Morphohaptoderus from China. The following characters are considered important both for species determination and for inferring phylogenetic relationships: setae on the submentum, number of setigerous pores on elytral interval 3, and the median lobe of the aedeagus, particularly the modification of the apical lamella and the presence of ventral ridges.</p><p>In most members of Pterostichus, the submentum has two setae on each side: a longer medial seta and a shorter lateral seta. In some cases, the lateral seta may be absent, resulting in only one seta on each side of the submentum. Based primarily on this character, the Chinese species of Morphohaptoderus can be classified into two major groups. Division I: The submentum has two setae on each side. Species in this group tend to have smaller body sizes; if the apical lamella of the aedeagus is modified, it is hooked on the right margin; elytral interval 3 has two or more (usually three or four) setigerous pores, with the basal pore always adjacent to stria 3. Fifteen described species belong to this group, primarily distributed in the high-altitude Hengduan Mountain System in Sichuan and Yunnan provinces, with a few also occurring in Shaanxi and Gansu. Division II: The submentum has only one seta on each side. Species in this group exhibit a body size range from very small to large; the apical lamella of the aedeagus is often modified, with a denticle on the left margin; the median lobe of the aedeagus often has ventral ridge; and elytral interval 3 normally has three or fewer (usually two) setigerous pores, all of which are often adjacent to stria 2 (except for three species in Hubei). Twenty-five described species belong to this group, including all 14 species distributed in Hubei, seven additional species of the maximus group (defined below), and four remaining species: P. schuelkei Sciaky &amp; Wrase, 1997, P. wenxianensis Allegro &amp; Sciaky, 2010, P. janatai Sciaky &amp; Wrase, 1997, and P. parvicollis Sciaky &amp; Wrase, 1997 . These species are primarily distributed in the relatively low-altitude Qinling Mountain System in Hubei and Shaanxi, with a few also occurring in mountainous regions of southern China.</p><p>In Division II, 13 species share a similar aedeagus type, characterized by a large denticle on the left margin of the median lobe and a strongly downward-bent apex of the apical lamella (Figs 1 C, 12, 13). A species group named the maximus group is proposed for these species, as this group is clearly monophyletic based not only on the above specific characters of the male genitalia but also on the following: the ventral margin of the aedeagus is more or less ridged; females often exhibit granular microsculpture on the elytra, giving them a shagreen appearance; and elytral interval 3 usually has two setigerous pores, with the first pore always adjacent to stria 2. Compared with other species in Division II, P. hubeicus Facchini &amp; Sciaky and P. yaotiao sp. nov. are most closely related to the maximus group, as they also possess a denticle (although very small and indistinct) on the left margin of the apical lamella of the aedeagus.</p><p>Except for the six species from Hubei (the first six species in the present paper), the following seven species also belong to the maximus group: P. maximus Tschitschérine, 1889; P. dundai Sciaky, 1994; P. huashanus Sciaky, 1994; P. lingshanus Sciaky &amp; Wrase, 1997; P. chungkingi Jedlička, 1932; P. irideus Sciaky, 1994; and P. guizhouensis Sciaky, 1997 . The first four species listed are distributed in the Qinling Mountains, with one species ( P. maximus) from Gansu and the remaining species from Shaanxi. The last three species are distributed in three isolated mountain ranges: Jinfo Mountain (Chongqing), Emei Mountain (Sichuan), and Fanjing Mountain (Guizhou).</p><p>To facilitate descriptions of male genitalia in the maximus group, it is necessary to introduce three morphological terms: lamellar denticle is used to describe the tooth-like structure formed by the upward bending of left margin of apical lamella; lamellar apex refers to the portion of apical lamella located distally from the base of lamellar denticle; and lamellar base refers to the portion of apical lamella located proximally to the lamellar denticle (Fig. 1 C). When describing species in the maximus group, the lengths of these three parts were measured to characterize variations in the apical lamella. Measurements were taken from the intersection points of their axes in the left lateral view, extending to the apical margin of the apical orifice and to the apical tips of the lamellar apex and lamellar denticle (Fig. 1 C).</p><p>In the maximus group, the ventral surface of the median lobe of the aedeagus typically bears three ridges. The right ridge is located on the right-ventral margin of the median lobe (the right-ventral margin corresponds to the left side of the median lobe in ventral view). When entire, it extends from the aedeagal base to the extreme apex, forming a continuous margin on the right-ventral side of the basal portion and apical lamella; however, it is partially absent in many species. The median ridge is positioned along the midline of the ventral surface. When entire, its base does not reach the aedeagal base, and its apex extends at most to the midlevel of the apical orifice. The left ridge is situated on the left-ventral margin of the median lobe. Its base nearly reaches the aedeagal base, with a straight or sinuate structure near the base, and the apex terminates at the left-basal corner of the apical orifice. Among the six Hubei species of the maximus group, all three ridges described above are fully developed only in P. lisao sp. nov. (Fig. 14 B, C). In the other species, some ridges are absent or poorly defined.</p><p>Key to species of subgenus Morphohaptoderus Tschitschérine, 1898 from Hubei</p></div>	https://treatment.plazi.org/id/9661F056BB13544A849004C3B97A264C	Public Domain	No known copyright restrictions apply.

Male genitalia with relatively small lamellar tooth, about half as long as the lamellar apex; ventral surface with two short ridges.</p><p>Comparisons.</p><p>The new species, P. wangshu sp. nov., is different from all other related species of the subgenus in Hubei by the antennomere 3 with a few accessory setae along the inner margin (Fig. 1 A). For the very indistinctly depressed sternite VII in males, P. wangshu sp. nov. could be most related to P. shennongjianus Facchini &amp; Sciaky. But these two species are different in the following aspects: (1) antennomere 3 with accessory setae in P. wangshu sp. nov.; (2) in P. wangshu sp. nov., the area between the pronotal lateral channel and the outer sulcus of the basal fovea is typically less convex (Fig. 3 F), forming a shallower ridge than in P. shennongjianus; (3) elytral interval 3 with two setigerous pores in P. wangshu sp. nov., but usually with three or more pores in P. shennongjianus; (4) in the male genitalia of P. wangshu sp. nov., the lamellar denticle smaller than in P. shennongjianus, with its length about half length of the lamellar apex (Fig. 12 D, E); (5) the ventral surface of median lobe with two ridges in P. wangshu sp. nov.

Moreover, these species are also very different on the setae of antennomere 3 and the male genitalia. Compared with P. quyuani sp. nov., the male genitalia of P. wangshu sp. nov. is different for the lamellar denticle much smaller, only about half length of the lamellar apex (Fig. 12 D, E).

In “ Li Sao, ” Wangshu (望舒) is the name of the fairy who drives the chariot for the moon. It can also be referred to as the moon itself in other literature.
