Hexarhopalus (Leprocaulus) xuhaoi Jiang, Bai, Ren & Wang sp. nov.
( Figs 14–15 View FIGURE 14 View FIGURE 15 , 21J View FIGURE 21 )
Type material (2 spec. 1 ♂, 1 ♀). Holotype: CHINA: ♂, labeled ‘ China: Xizang, Chiayu County (ḔṚss), Zhuwagen Town (n'ãĕẘ), Longgu Village (żåń), 2016.VII.06, 2600m, Xu Hao & Qiu Jian-Yue leg.’ ( MHBU) . Paratype: China : 1 ♀, same collected data with holotype ( MHBU) .
Description. Male ( Figs 14A View FIGURE 14 , 15A – G View FIGURE 15 ). Body elongate, black, convex and dull-shiny.
Head ( Fig. 15A View FIGURE 15 ) slightly wider than long, dorsal surface crude, finely covered with short hair, punctures small. Labrum narrower than clypeus, covered with bristles of medium length in apical portion. Antennal tubercles weak, antenna ( Fig. 15B View FIGURE 15 ) shorter than the combined length of head and pronotum, clubs loosely formed by apical four antennomeres. Antennomere I slightly expanded; II shortest, longer than wide; III longest, about twice as long as II, IV-VII similar, shorter than III, apical four dark brown, expanded, XI with rounded apex.
Pronotum ( Fig. 15A View FIGURE 15 ) about as long as wide, widest near middle, dorsal surface crude, with shallow and mussy wrinkles, and covered with small and sparse punctures and much short hairs. Groove of pronotum deep at base, the back angle oblique indentation slightly short, deep, curved forward and upward, much wide, shallow and not obvious at lateral part, median line not obvious.
Elytra about 2.5 times as long as wide, widest at apical 1/3, shoulders strong, Disc with regular rows of orderly longilineal punctures, and covered with irregular rows of small tubercles. Scutellum transverse, near triangular. Hind wings fully developed.
Femora slightly expanded, all tibiae covered with brown setae at apex, protibiae slightly curved and without modification, mesotibiae slightly curved, metatibiae straight.
Aedeagus ( Figs 15 View FIGURE 15 C–E), near symmetrical, abdominal ventrite VIII ( Fig. 15G View FIGURE 15 ) deeply split medially at posterior margin and with long dense hair at hind margin. Spiculum gastrale ( Fig. 15F View FIGURE 15 ) dissymmetrical, short, with large apical lobes.
Measurements. AnL 3.23 mm, BL 12.01 mm, HL 1.38 mm, HW 2.06 mm, PL 2.48 mm, PW 2.79 mm, EL 8.15 mm, EW 4.11 mm, AL 1.53 mm.
Female ( Figs 14B View FIGURE 14 , 15H – I View FIGURE 15 ). Similar to males. Ventrite VIII ( Fig. 15H View FIGURE 15 ) not split medially at posterior margin and covered with long dense hairs. Spiculum ( Fig. 15I View FIGURE 15 ) strong and straight, apex rounded. Apex of ovipositor ( Fig. 15I View FIGURE 15 ) with one long hair and two much shorter hairs.
Measurements. AnL 3.45 mm, BL 13.14 mm, HL 1.48 mm, HW 2.28 mm, PL 2.78 mm, PW 3.08 mm, EL 8.91 mm, EW 4.50 mm.
Comparative Notes. Hexarhopalus (Leprocaulus) xuhaoi sp. nov. can be easily separated from its congeners by the following characters: shallow wrinkles on pronotum; groove of pronotum vanishing anteriorly and laterally; and femora expanded weakly. The new species is similar to Hexarhopalus (Leprocaulus) xui Ren & Xu, 2011 ( Fig. 20C View FIGURE 20 ) in its general appearance, but can be separated by: 1) having the whole body dark black (vs. brown); 2) shallow wrinkles on pronotum; 3) smaller tubercles on elytra; 4) broader ventrite VIII of females; 5) spiculum narrow at base; 6) elytral punctures longilineal and orderly.
Distribution. China: Xizang.
Biology. Unknown.
Etymology. This species is named in honor of our friend Dr. Hao Xu, who collected the type series.
