Domene (Macromene) tui Z. Peng View in CoL and L.-Z. Li, new species
( Figs 4C View FIGURE 4 , 7 View FIGURE 7 )
Type material (1 ♂). Holotype ♂: “ China: Guizhou Prov., Xishui, Sanchahe , 28°30'01''N, 106°24'12''E, 890 m 12.VII.2015, Peng, Jiang, Tu & Zhou leg.” ( SNUC) GoogleMaps .
Description. Measurements (in mm) and ratios: BL 11.68, FL 5.84, HL 1.54, HW 1.67, AnL 4.06, NW 0.52, PL 1.83, PW 1.59, EL 1.39, EW 1.90, TiL 2.22, TaL 1.39, AW 1.76, AL 1.46, HL/HW 0.92, HW/PW 1.05, HL/PL 0.84, NW/HW 0.31, PL/PW 1.15, EL/PL 0.76.
Habitus as in Fig. 4C View FIGURE 4 . Body blackish brown; legs with blackish brown femora and brown tibiae; antennae blackish brown to brown.
Head ( Fig. 7A View FIGURE 7 ) weakly transverse, widest behind eyes; punctation fine, weakly umbilicate, and very dense. All antennomeres longer than broad; antennomeres IV–X of equal length; antennomere I 1.5 times, II 0.9 times, III 1.1 times, XI 1.0 times as long as IV. Maxillary palpus slender, preapical joint 2.6 times as long as broad.
Pronotum ( Fig. 7B View FIGURE 7 ) short, widest in the middle; lateral margins distinctly convex in dorsal view; punctation coarse and dense; midline with narrow glossy line.
Elytra ( Fig. 7C View FIGURE 7 ) broad; disc with weakly pronounced, narrow and long lateral ridges and with rudiments of such ridges anteriorly, with weak impression; macropunctation coarse and partly somewhat seriate; interstices with irregular and dense micropunctation. Hind wings present. Protarsomeres I–IV moderately dilated.
Abdomen with very fine and dense punctation on tergites III–VIII; posterior margin of tergite VIII weakly convex; interstices with distinct microreticulation; posterior margin of tergite VII with palisade fringe.
Male. Sternites III–VI unmodified; sternite VII ( Fig. 7D View FIGURE 7 ) with moderately dense dark setae in shallow median impression posteriorly, posterior margin shallowly concave in the middle; sternite VIII ( Fig. 7E View FIGURE 7 ) transverse, with shallow and extensive median impression, this impression with stout black setae, posterior excision deep, on either side of the posterior excision with a dense cluster of dark setae; aedeagus as in Figs 7F–G View FIGURE 7 , ventral process stout, evenly curved and apically acute in lateral view; dorsal plate long, apical portion distinctly sclerotized and apically acute in lateral view, basal portion very short; internal sac with dark membranous apical structures.
Female. Unknown.
Comparative notes. Based on the similar chaetotaxy and shape of the male sternites VII–VIII, D. tui belongs to the D. malaisei species group. It can be distinguished from other species of the group by the weakly transverse head, the somewhat coarser macropunctation of the elytra, the chaetotaxy of the male sternite VIII and the differently shaped ventral process of the aedeagus. For illustrations of the species of the D. malaisei group see Assing (2015) and Feldmann et al. (2014).
Distribution and natural history. The type locality is situated in Sanchahe to the northeast of Xishui, northern Guizhou. The specimens was sifted from leaf litter in a pine forest at an altitude of 890 m.
Etymology. The species is named for Mr. Yue-Ye Tu, who collected the type specimen.
