Type species: Peltocercyon coomani d'Orchymont.</p><p>Diagnosis (Figs 2, 3). Body broadly oval, moderately convex, its outline not interrupted between pronotum and elytra. Antenna with 9 antennomeres, antennal bases not concealed by lateral parts of clypeus, club (antennomeres 7–9) compact. Elytra with 10 punctate striae, intervals flat or slightly convex in posterior half. Mentum (M) subtrapezoidal, anterior margin slightly concave medially. Posterior tentorial pits (PTP) of head simple or forming two large depressions. Prosternum (PR) tectiform or slightly bulging at middle portion, with sharp median carina; lateral portion of prosternum with ridge (R) (Fig. 2B, C) or without it (most species; Fig. 2A); prosternal process (PP) notched (Fig. 2B) or pointed posteriorly (Fig. 2C). Antennal groove (AG) distinct with outer margin convex, not reaching lateral margin of prothorax. Mesoventral plate (MP) spindle-shaped, posterior apex overlapping the anterior ridge of metaventrite in a single point (most species) (Fig. 2A, C) or subtriangular and widely contacting the anterior margin of metaventrite ( P. coomani) (Fig. 2B). Metaventrite densely pubescent except for the raised central area (CAM); anterior ridge of metaventrite (ARM) bent backwards at anterolateral corner and forming an arcuate ridge (AR); metaventrite with complete femoral lines (FL) crossing the arcuate ridges and reaching anterolateral corners of metaventrite. Epipleuron wedge-shaped and oblique at anterior half of elytron. First abdominal ventrite (FAV) sharply carinate medially. Male with a sucking-disc shaped appendage on maxilla. Male genitalia (Fig. 3) of typical form for subtribe Megasternina, with median lobe (MeL) of the aedeagus reaching deeply into phallobase; median lobe shorter than tegmen (Teg). Gonopore (Gop) triangular, located slightly below the apex of medial lobe. Phallobase (Phb) shorter than paramere (Prm). Paramere in two forms: (1) paramere expanded and broad apically, with a rounded or truncated apex; inner face of the paramere without fringe of setae (Fig. 3B); (2) paramere slightly widened subapically and then gradually narrowing towards apex, with a bluntly pointed apex; inner face of the paramere with a fringe of long setae subapically (Fig. 3A, C). Abdominal sternite 9 has a median portion (MeP) developed as a tongue-like projection (Fig. 3E).</p><p>Biology (Figs 36–40). Occur in decaying plant material, or in faeces of large herbivorous mammals. Adults can be attracted to light, or to traps baited with excrement or carrion.</p><p>Distribution (Figs 41–45). The genus is distributed in the southeastern part of Asia, ranging from Sri Lanka eastward across Southeast Asia, southern and central China, Japan, extending north to the Russian Far East and south to Sumba Island in Indonesia. Oriental Region: China (Guangdong, Guangxi, Guizhou, Taiwan, Yunnan, southern part of Xizang), Cambodia, Indonesia (East Kalimantan, Sumatra, Sulawesi, Sumba), Vietnam, Singapore, Sri Lanka, India (northeast India), Laos, Malaysia (Sabah, Sarawak, Selangor, Langkawi), Myanmar, Nepal, Thailand, Philippines (Mindanao). Palearctic Region: China (Shaanxi, Hubei, Sichuan), Japan, Russia (Far East), South Korea.</p><p>A check list of the species of genus Peltocercyon</p><p>Based on morphology, we define two species groups ( P. splendidus group and P. vagus group) that undoubtedly consist of closely related species. The monophyly of the P. splendidus group was confirmed by our DNA analyses. Additional DNA data are needed to properly understand the relationships of the remaining species, hence we leave the remaining species without species group assignment for the moment.</p><p>Species not assigned to a species group:</p><p>Peltocercyon basirugosus sp. nov.

Dorsal surface with uniform dense and coarse crescent-shaped punctures; interstices between punctures smooth. Anterior margin of clypeus with a marginal bead. Eyes moderately large, separated by ca. 5× the width of one eye. Mentum subtrapezoid, ca. 2.0× as wide as long, slightly depressed anteromedially; anterior margin of mentum slightly concave; with dense transverse microsculpture and coarse punctures (Fig. 6A). Posterior tentorial pits small, not depressed (Fig. 6A). Antennae with 9 antennomeres; antennal club (antennomeres 7–9) compact and densely pubescent. Maxillary palpomere 2 strongly swollen in apical half, longer than palpomere 3; palpomere 4 almost symmetrical, slightly longer than palpomere 3. Each maxilla with a sucking-disc shaped appendage in male.</p><p>Thorax. Pronotum widest posteriorly, gradually narrowed anteriad, with finer and sparser crescent-shaped punctures than those on head. Lateral margins of pronotum narrowly rimmed, the rim overlapping anterior and posterior corners, anterior and almost all of posterior margin without rim. Prosternum gradually raised at middle portion and tectiform medially, with sharp median carina; middle portion of prosternum rugulose; lateral portion of prosternum without ridge; depressed lateral portion of prosternum smooth; prosternal process deeply notched posteriorly (Fig. 6B). Antennal groove of moderate size, outer lateral margin moderately convex (Fig. 6B). Mesoventral plate spindle-shaped and elongate, surface slightly convex and shining; ca. 4× as long as wide, posterior apex overlapping the anterior ridge of metaventrite in a single point (Fig. 6C). Scutellar shield triangular, longer than wide, with punctures finer than those on pronotum. Elytra widest at anterior third; each elytron with 10 rows of punctate striae, striae moderately impressed; striae 6, 8 and 9 not reaching anterior margin of elytron; stria 10 short, only ending at posterior third of elytron; intervals of striae flat, with fine ground punctures, intervals between punctures smooth.

Adults live inside rotten banana trunks, sometimes attracted by decaying bamboo shoots in forest.</p><p>Etymology. The specific name is derived from Latin basalis (= basal) and rugosus (= rugged), referring to the first abdominal ventrite that is coarsely ridged basally.</p><p>Remarks. This new species is similar to Peltocercyon vividus and P. kouwenkaii sp. nov. in form and colour. It can be distinguished from P. vividus by the smooth depressed lateral portions of prosternum (Fig. 6B) (with shagreen in P. vividus, Fig. 20B), paramere distinctly expanded apically (Fig. 5D) (slightly expanded apically in P. vividus, Fig. 19D). It can be distinguished from P. kouwenkaii by the punctation of the pronotum consisting of punctures of single size (consisting of two sizes of punctures in P. kouwenkaii, Fig. 12A), and lateral area of metaventrite with scattered coarse punctures (Fig. 6D) (without distinct coarse punctures in P. kouwenkaii, Fig. 12E).</p><p>Distribution (Fig. 44).

Elytra shiny, spaces between ground punctation smooth. Mentum with sparse and fine punctures (Fig. 10A). Posterior tentorial pits of head moderately large, forming two depressions (Fig. 10A). Prosternum sharply carinate medially; lateral portion of prosternum smooth, demarcated from the middle portion by an oblique ridge; prosternal process deeply notched posteriorly (Fig. 10B). Antennal grooves narrow (Fig. 10B). Mesoventral plate subtriangular, posterior margin concave, broadly contacting the mesoventrite (Fig. 10C). Arcuate ridge of metaventrite distinct, strongly bent backwards (Fig. 10D). Lateral area of metaventrite without coarse punctures (Fig. 10D). First abdominal ventrite without longitudinal sculptures basally (Fig. 10E). Male genitalia (Fig. 9F–I): paramere slightly widened subapically and then gradually narrowing towards apex, apex bluntly pointed and slightly curved inwards; inner face of the paramere with a fringe of long setae subapically and with several apical setae (Fig. 9F, H). Median lobe nearly parallel sided, narrowed subapically; apex bluntly pointed (Fig. 9G).</p><p>Redescription. Form and Colour (Fig. 9A–E). Total length 2.8–3.1 mm; maximum width 1.7–2.1 mm. Body broadly oval, not parallel-sided in the middle, rather convex. Dorsum reddish brown and shiny. Elytron with a dark brown to black obliquely transverse patch across 5–10 striae lateromedially, some individuals without this kind of patch and almost uniform in colour, some elytron with a triangular brown to black patch lateromedially; sometimes dark reddish brown in anterior third and yellowish on posterior third, making elytron tricolored. Maxillary palpi and labial palpi yellowish brown; antennae yellowish brown with club dark brown. Ventral surface dark yellowish to reddish brown.</p><p>Head. Dorsal surface with uniform dense and coarse crescent-shape punctures; interstices between punctures smooth. Anterior margin of clypeus with a marginal bead. Eyes of moderate size, separated by ca. 5× the width of one eye. Mentum subtrapezoid, ca. 1.5× as wide as long, strongly depressed anteromedially; anterior margin of mentum slightly concave; with fine and sparse punctures (Fig. 10A). Posterior tentorial pits forming depressions (Fig. 10A). Antennae with 9 antennomeres; antennal club (antennomeres 7–9) compact and densely pubescent. Maxillary palpomere 2 strongly swollen in apical half, longer than palpomere 3; palpomere 4 almost symmetrical, slightly longer than palpomere 3. Each maxilla with a sucking-disc shaped appendage in male.</p><p>Thorax. Pronotum widest posteriorly, gradually narrowed anteriad, with coarser and sparser crescent-shape punctures than those on head. Lateral margins of pronotum narrowly rimmed, the rim overlapping anterior and posterior corners, anterior and almost all of posterior margin without rim. Prosternum sharply carinate and pubescent at middle portion; lateral portion of prosternum glabrous, demarcated from the middle portion by a distinct oblique ridge; prosternal process deeply notched posteriorly (Fig. 10B). Antennal groove narrow, outer lateral margin slightly convex (Fig. 10B). Mesoventral plate subtriangular and elongate, surface slightly concave and shining; ca. 3× as long as wide, gradually narrowing anteriorly; posterior margin concave, broadly contacting anterior ridge of metaventrite (Fig. 10C). Scutellar shield triangular, longer than wide, with punctures finer than those on pronotum. Elytra widest at anterior third; each elytron with 10 rows of punctate striae, striae moderately impressed; striae 6, 8 and 9 not reaching anterior margin of elytron; stria 10 short, only ending at posterior third of elytron; intervals of striae flat, with fine ground punctures, intervals between punctures glabrous. Epipleuron wedge-shaped and strongly oblique at anterior half of elytron. Central area of metaventrite uniformly punctate and bare, lateral areas of metaventrite densely pubescent and without coarse punctures; anterior ridge of metaventrite strongly bent backwards at anterolateral corner and forming an arcuate ridge; metaventrite with complete femoral lines crossing anterolateral arcuate ridges and reaching anterolateral corners of metaventrite; anterior ridge of metaventrite continuous with the arcuate ridge at the crossing point, with a pit behind anterior ridge medially and a pit on each side at the crossing point of femoral line and anterolateral arcuate ridges (Fig. 10D).</p><p>Legs. Profemora bare ventrally, with very fine punctures; mesofemora with coarser setiferous punctures than those on metafemora. Tibiae with small lateral spines. Tarsi with sparse gold ventral setae, first metatarsomere about as long as metatarsomeres 2–3 combined.</p><p>Abdomen. Abdominal ventrites densely pubescent. First ventrite sharply carinate medially, more densely pubescent than other ventrites but without a series of short longitudinal sculptures basally (Fig. 10E).</p><p>Male genitalia. Paramere widest basally, gradually narrowing towards apical fourth, then slightly widen subapically and then gradually narrowing towards apex, apex bluntly pointed and slightly curved inwards; inner face of paramere with a fringe of long setae subapically and several apical setae (Fig. 9F, H). Phallobase slightly shorter than parameres; nearly parallel sided, manubrium gradually narrowed and asymmetrical at the base (Fig. 9F, H). Median lobe widest in the middle, parallel sided, narrowed subapically, apex bluntly pointed (Fig. 9G). Median projection of sternite 9 slender and rounded basally; lateral struts slightly longer than median portion (Fig. 9I).</p><p>Biology (Fig. 39A–D). Occurs in forests.Adults live in decaying plant material in rainforest and can be attracted in large numbers by fermented fruits such as rotting banana or jackfruit ( Artocarpus).</p><p>Remarks. Very characteristic species, it can be easily recognized by the lateral portions of prosternum demarcated from the middle portion by a pair of oblique ridges (Fig. 10B) and the mesoventral plate subtriangular and broadly contacting anterior ridge of metaventrite (Fig. 10C). There is a lot of variation between individuals of this species, especially in the elytral coloration. Most individuals have a dark brown to black obliquely transverse patch across 5–10 striae lateromedially, but some individuals lack this kind of patch and are almost uniform in color, some have elytron with a triangular brown to black patch lateromedially.</p><p>Distribution (Fig.42). China (Hainan, Yunnan), Indonesia (West Sumatra), Laos (Khammouane, Xiangkhouang, Luang Prabang, Bolikhamsai, Houaphanh), Vietnam (Hoa Binh), Thailand (Mae Hong Son, Surat Thani) Malaysia (Selangor, Sarawak), Indonesia (West Sumatra).

Lateral margins of pronotum narrowly rimmed, the rim overlapping anterior and posterior corners, anterior and almost whole posterior margin without rim. Prosternum gradually raised at middle portion and tectiform medially, with sharp median carina; lateral portion of prosternum without ridge and shagreened; prosternal process deeply notched posteriorly (Fig. 20B). Antennal grooves moderate in size, outer lateral margin moderately convex (Fig. 20B). Mesoventral plate spindle-shaped and elongate, surface slightly convex and shining; ca. 5–6 × as long as wide, posterior apex overlapping the anterior ridge of metaventrite in a single point (Fig. 20C). Scutellar shield triangular, longer than wide, with punctures finer than those on pronotum. Elytra widest at anterior third; each elytron with 10 rows of punctate striae, striae moderately impressed; striae 6, 8 and 9 not reaching anterior margin of elytron; stria 10 short, only ending at posterior third of elytron; intervals of striae flat, with fine ground punctures, intervals between punctures smooth. Epipleuron wedge-shaped and strongly oblique at anterior half of elytron. Central area of metaventrite uniformly punctate and glabrous, lateral areas of metaventrite densely pubescent and with some coarse punctures; anterior ridge of metaventrite strongly bent backwards at anterolateral corner and forming an arcuate ridge; metaventrite with complete femoral lines crossing the anterolateral arcuate ridges and reaching anterolateral corners of metaventrite (Fig. 20C). Anterior ridge of metaventrite continuous with the arcuate ridge at the crossing point (Fig. 20C).</p><p>Legs. Profemora bare ventrally, with very fine punctures; mesofemora with coarser setiferous punctures than those on metafemora. Tibiae with small lateral spines. Tarsi with sparse gold ventral setae, first metatarsomere about as long as metatarsomeres 2–3 combined.</p><p>Abdomen. Abdominal ventrites densely pubescent. First ventrite sharply carinate medially, with a series of short longitudinal sculptures basally (Fig. 20D), more rough than other ventrites.</p><p>Male genitalia. Paramere widest basally, slightly expanded and obliquely truncate apically; inner face of paramere without fringe of setae (Fig. 19D, F). Phallobase shorter than parameres; nearly parallel sided, manubrium gradually narrowed and asymmetrical at the base (Fig. 19D, F).

Sharp (1884) described Cercyon vagus based on two female specimens collected from Oyama and Miyanoshita, Japan. In the original description, the species was characterized by deeply impressed elytral striae and convex intervals, though no details were provided regarding the ventral morphology. Ryndevich (2006) placed this species in the subgenus Conocercyon Hebauer, 2003, based on the presence of arcuate ridges on the anterolateral corners of metaventrite. We examined two type specimens and revealed that the species also has complete femoral lines on the metaventrite that cross the anterolateral arcuate ridges at the anterolateral corners of metaventrite, i.e. the diagnostic character of Peltocercyon (Fig. 31E). Moreover, the species closely resembles other Japanese Peltocercyon species by external morphology. We therefore transfer the species from Cercyon to Peltocercyon . Peltocercyon vagus can be distinguished from P. sanaii (Hoshina, 2008), comb. nov., and P. subopacipennis (Nakane, 1965) by the sparse microreticulation between the ground punctation on the elytra, which makes the elytra less opaque (Fig. 31D) (the elytra in the latter two species are densely microreticulate and much more opaque; Fig. 32A, C).</p><p>Distribution (Fig. 41).

No detailed description of the metaventrite was provided in the original description of this species, and the drawing provided by Hoshina (2008; fig. 7) seems inaccurate for the structures on the mesoventrite. Based on the examination of photographs of paratypes and actual specimens identified as Cercyon sanaii by H. Hoshina, we found that the species has arcuate ridges on the anterolateral corners of the metaventrite and that they cross the complete femoral lines, indicating that the species belongs to Peltocercyon . Hoshina (2008) compared this species to Cercyon vagus (= Peltocercyon vagus), indicating that it differs by more opaque elytra, compared to the smooth elytra of Cercyon vagus (in fact, the latter species also has microreticulation on elytra, though it is sparser, resulting in a shinier appearance, see above). Cercyon sanaii was not mentioned by Hoshina (2016) who transferred Cercyon subopacipennis Nakane, 1965 to Peltocercyon, neither in the descriptions of the other new Japanese Peltocercyon species by Hoshina (2018, 2021). When compared with all these species, Peltocercyon sanaii seems very similar to P. ohoni Hoshina, 2021 in both external morphology and male genitalia, and we suspect both names may in fact refer to the same species. However, since we have not studied and compared type specimens of both species, we treat them as separate species here.</p><p>Distribution (Fig. 41).
