Description

Holotype male. Body 28.6 mm long, widest just after elytral humeri (10.8 mm). Length of different body parts (mm): head (3.3), antenna (54.5), pronotum (5.1), elytra (20.4); width: head (5.9), pronotal apex (6.2), pronotal base (6.6), elytral humeri (10.1).

Habitus (Fig. 1 A and B). Body oval. Integumentary colour of body and appendages blackish; eyes black; elytra blackish with weak green sheen. Frons, genae and vertex almost glabrous. Temples moderately clothed with slender, recumbent, pale pubescence. Scape and pedicel densely clothed with short, recumbent, pale pubescence; in addition, pedicel with whitish pubescence at mesial side. Antennomeres III-XI annulated by whitish pubescence at bases and apices and clothed with dark brown pubescence in middle parts; annulations broadening apically and apical three antennomeres almost entirely covered with whitish pubescence, except in middle of mesial side. Pronotum almost glabrous, inserted with several moderately long, suberect, dark brown setae after lateral spines. Scutellum clothed with whitish pubescence. Elytra mostly glabrous; each elytron provided with several small maculae of white pubescence, roughly arranged in four transverse rows and one relatively large macula along apical margin. Ventral surface predominantly clothed with fine pale pubescence, laterals of metasternum and abdominal sternites III-VII provided with maculae of whitish pubescence. Legs mostly clothed with dark brown pubescence, but with bluish-white pubescence on basal half of tibiae and tarsal dorsum.

Head subcylindrical, 1.7 times wider than long, widest at posterior margin of lower eye lobes, slightly narrowed posteriorly. Vertex, frons and genae sparsely covered with fine punctures, interstices microreticulate. Anteclypeus membranous, transverse, without setae or evident punctures; anterior margin straight. Frons with fine median groove extending from anterior margin to occiput. Vertex moderately concave; antennal tubercles prominent.

Mouthparts. Labrum wider than long, covered with short brownish setae on dorsal surface, especially dense along anterior margin and with long, strong, blackish setae in apicolateral areas; anterior margin gently emarginate. Mandible short, regularly arcuate at outer edge. Maxillary and labial palpi with ultimate palpomeres fusiform, truncated at apices.

Antennae moderately long, 1.9 times as long as body, with apical five antennomeres exceeding elytral apices. Antennomeres with length ratio from base to tip: 6.71 - 1.00 - 10.22 - 9.07 - 7.69 - 7.35 - 7.28 - 6.92 - 6.37 - 6.14 - 9.72. Scape subcylindrical, robust, gradually thickening towards apex, with distinct cicatrix. Pedicel knob-like, short, distinctly thinner than scape. Antennomere III the longest, 1.7 times longer than pronotum, 1.5 times longer than scape and 1.1 times longer than IV. Antennomeres III-X straight, gradually decreasing in length. Antennomere XI arcuate, 1.6 times longer than X.

Pronotum subcylindrical, slightly widening basally, 0.8 times as long as basal width, widest at lateral spines. Lateral spine conical, with subacute apex laterally directed and slightly retrousse. Posteromedial callus moderately developed and elevated. Surface with a few umbilicated granules and wrinkles between lateral spine and posteromedial callus.

Scutellum subtriangular, narrowly rounded at apex. Surface densely and finely punctuated.

Elytra semi-oval, 2.0 times as long as humeral width, widest just after humeri. Humeral width 1.5 times wider than pronotal base. Lateral margin gradually narrowing towards conjointly rounded apices; sutural angle round. Surface smooth, without any granules, sparsely covered with fine punctures, interstices microreticulate.

Legs. Femora moderately stout; metafemora reaching posterior margin of abdominal sternite VI. Tibiae moderately long; pro- and mesotibiae gently incurvate around apical 1/3; metatibiae straight. Tarsomere I the longest, but not longer than II+III; III distinctly bilobed.

Ventral side. Prosternum smooth; prosternal process almost smooth, apically truncated. Mesosternal process with one strong middle tubercle. Metaventrite with fine median groove extending from sub-base to apical 3/7. Metanepisternum wedge-like; anterior margin widely rounded; ventral margin gently incurved at anterior area and slightly wide at posterior area.

Abdomen. Abdominal tergite VII (Fig. 3 C) subhexagonal, almost simply rounded at posterior margin; tergite VIII (Fig. 4 A) subhexagonal, distinctly emarginate at posterior margin, hardly depressed on dorsal surface (Fig. 4 C). Abdominal sternites densely and finely punctate; sternite VII (Fig. 3 D) subtrapezoidal, slightly emarginate at middle of posterior margin; sternite VIII (Fig. 4 B) with sclerotised area rather narrow, widely emarginate at middle of posterior margin. Spiculum gastrale (Fig. 4 D and E) with stem 2.1 times longer than branches; stem straight, except hook-like base in lateral view (Fig. 4 F).

Male genitalia. Tegmen (Fig. 5 A and B) widest at basal 3/7, moderately curved ventrally in lateral view (Fig. 5 C); parameres 1/4 length of tegmen, moderately elongate, gradually convergent towards round apex, apex with long setae (Fig. 5 D). Median lobe (Fig. 5 E and F) longer than tegmen, moderately curved ventrally in lateral view (Fig. 5 G); dorsal plate (Fig. 5 H) abruptly narrowed from subapex, rounded at apical margin; ventral plate (Fig. 5 H) distinctly longer than dorsal plate, narrowed from subapex, rounded at apical margin; basal struts (Fig. 5 E and F) half length of median lobe.

Male paratypes. Body 28.1-28.8 mm long. Five male types have the same body colour, without evident variations. Whitish or white pubescence stained with bluish tint in different degrees. Some males sparsely clothed with white pubescence on anterolateral and lateral areas of pronotum (lost in holotype). Due to the condition of different specimens, whitish or white pubescence or maculae may be distinct, vague or absent.

Female paratypes. Body 34.8-35.6 mm long, widest just after elytral humeri (13.8 mm). Length of different body parts (n = 2, average value, mm): head (3.9), antenna (56.1), pronotum (6.2), elytra (25.3); width: head (7.3), pronotal apex (7.6), pronotal base (8.2), elytral humeri (13.3). Antennomeres with length ratio from base to tip: 5.24 - 1.00 - 6.78 - 5.88 - 5.02 - 4.39 - 4.35 - 4.11 - 3.84 - 3.66 - 5.24.

Similar to male in general appearance, but distinct by the following characters: body much larger (Fig. 1 C and D); antennae much shorter, about 1.6 times as long as body, with apical four antennomeres exceeding elytral apices; ventral surface with whitish maculae broader; abdominal tergite VII (Fig. 3 A) and sternite VII (Fig. 3 B) deeply emarginate in middle of posterior margins; spermatheca (Fig. 6 A) short, stout, bisinuate, also bisinuate in lateral view (Fig. 6 B).

Diagnosis

Anoplophora huangjianbini sp. n. is similar to A. imitator (White, 1858) (Fig. 2 A), A. elegans (Gahan, 1888) (Fig. 2 B), A. similis (Gahan, 1900) (Fig. 2 C), A. chiangi Hua & Zhang, 1991 (Fig. 2 D) and A. siderea Bi, Chen & Ohbayashi, 2020 (figs. 1-3 in Bi et al. 2020) by the distinctive antennal banding, which are annulated with whitish pubescence both at the bases and apices of antennomeres III-XI. However, the new species can be easily separated from them (except A. elegans ) by the granules (or granulation) lacking on the anterior part of elytra (Fig. 1 A and C). For A. elegans , it has a totally different pronotal and elytral design, with maculae (or rather bands) much larger/longer and more dense on pronotum, elytra, metasternum and abdominal sternites III-VII; besides, it also has large maculae around gena and frons and on mesepisternum (absent in A. huangjianbini sp. n.). Moreover, the new species is distinguished from its congeneric species by a combination of the following characters: abdominal tergite VII almost simply rounded at posterior margin (Fig. 3 C); tergite VIII distinctly emarginate at posterior margin (Fig. 4 A); sternite VIII with sclerotised area rather narrow, widely emarginate at middle of posterior margin (Fig. 4 B); spiculum gastrale with stem straight, except hook-like base in lateral view (Fig. 4 F); median lobe with dorsal plate abruptly narrowed from subapex and ventral plate narrowed from subapex (Fig. 5 H); basal struts half length of median lobe (Fig. 5 E); spermatheca (Fig. 6 A) short, stout, bisinuate, also bisinuate in lateral view (Fig. 6 A and B).

Etymology

The new species is dedicated to the collector of most type specimens, Mr. Jian-Bin Huang (Nanping, CHINA), an enthusiastic amateur entomologist. The name is a noun in the genitive case. "剑斌星天牛 (Pinyin: Jian Bin Xing Tian Niu)" is proposed for the Chinese common name of this new species.

Distribution
