Hexarhopalus (Leprocaulus) nanlingensis sp. nov.
( Figs 6–7 View FIGURE 6 View FIGURE 7 )
Type material. Holotype: CHINA: ♂, labeled ‘ China: Guangdong, Ruyuan County, Nanling National Forest Park, H: ~ 900m, 01.VIII.2019 ’ ( MHBU).
Description. Male ( Fig. 6A View FIGURE 6 ): Body elongate, black, convex, and shiny.
Head ( Fig. 6B View FIGURE 6 ) distinctly transverse, dorsal surface finely covered with small punctures, each puncture bearing a short, thin seta. Labrum narrower than epistoma, covered with medium-length bristles in apical portion, apical margin rounded. Antennal tubercles weak, antenna ( Fig. 7A View FIGURE 7 ) slightly shorter than combined lengths of head and pronotum, club loosely formed by apical four antennomeres. Relative lengths of antennomeres: 0.33: 0.23: 0.47: 0.33: 0.33: 0.33: 0.33: 0.30: 0.27: 0.27: 0.37; relative widths of antennomeres: 0.20: 0.17: 0.17: 0.17: 0.17: 0.17: 0.20: 0.27: 0.30: 0.30: 0.33. Antennomere I slightly expanded; antennomere II shortest, longer than wide; antennomere III longest, more than twice as long as natennomere II, antennomeres IV–VII similar, shorter than antennomere III, apical four dark brown, distinctly expanded, antennomere XI with rounded apically.
Pronotum ( Fig. 6B View FIGURE 6 ) about as long as wide, widest at apical 1/3, strongly convex, dorsal surface finely covered with small punctures and short setae, punctures much larger basally; mediolongitudinal sulcus wide and deep, about 2/3 pronotal length; pronotal groove deeper basally and shallower in anterior part; oblique indentation of posterior angle deep ( Fig. 7B View FIGURE 7 ), curved forward and upward. Prosternum distinctly rained before procoxae, surface weakly wrinkled, glabrous, apex of prosternal process obtuse.
Elytra more than twice as long as wide, widest at apical 1/3, humerus strong, disc with regular rows of regularly spaced punctures and small nodules; mesoscutellum transverse, nearly triangular; wings fully developed.
Metaventrite and abdomen shiny and finely covered with small punctures and minute setae; median sulcus of metaventrite quite shallow but present, extending from anterior margin to ca. 4/5 of metaventrite length. Abdominal ventrite I longest, about as long as combined lengths of ventrites III and IV; ventrite II longer than ventrite III; ventrites III and IV clearly concave; ventrite V shorter than combined lengths of ventrites III and IV, rounded apically; ventrite VIII ( Fig. 7F View FIGURE 7 ) with deeply medial emargination in posterior margin, with sparse long setae along hind margin.
Femora distinctly claviform medially, all tibiae covered with brown setae apically, pro- and mesotibiae slightly curved, metatibia straight, meso- and metatibiae slightly expanded apically; tarsomeres simple, distal pro- and mesotarsomeres each about as long as combines lengths of proximal four pro- and mesotarsomeres, respectively, distal metatarsomere about as long as combines lengths of metatarsomeres II–IV.
Aedeagus ( Figs 7C–E View FIGURE 7 ) symmetrical in dorsal view, distinctly curved in lateral view. Spiculum gastrale ( Fig. 7G View FIGURE 7 ) asymmetrical, short, with large apical lobes.
Measurements: BL 13.15 mm, HL 1.57 mm, HW 2.31 mm, PL 2.98 mm, PW 3.28 mm, EL 8.60 mm, EW 4.85 mm.
Female: Unknown.
Differential diagnosis. This new species is similar to H. (Leprocaulus) sinjaevi Bečvář & Purchart, 2008 from North Vietnam in its general appearance, but it can be distinguished from it by the strongly convex pronotum (in lateral view) with a wide and deep median sulcus, while the median sulcus narrow and shallow in H. (L.) sinjaevi .
Distribution. China: Guangdong.
Biology. Unknown.
Etymology. The specific epithet refers to the type locality, Nanling National Forest Park (Guangdong Province, Ruyuan County); adjective.
