description: <i>Lathrobium yipingae</i> Z. Peng and L.-Z. Li, new species (Map 1, Figs 9 C, 12) <b>Type material.</b> HOLOTYPE: Ƌ, labeled ‘ China: Jiangxi Prov., Jinggangshan, Shuikou, 26°32'42''N 114°08'03''E, 790–900 m, 30.VII.2014, Chen, Hu, Lv &amp; Yu leg.’ (SNUC). <b>Description.</b> Measurements (in mm) and ratios: BL 9.17, FL 4.17, HL 1.05, HW 1.20, AnL 2.22, PL 1.42, PW 1.30, EL 0.80, AL 1.40, HL/HW 0.88, HW/PW 0.92, HL/PL 0.74, PL/PW 1.09, EL/PL 0.56. Habitus as in Fig. 9 C. Body dark brown, legs brown, antennae brown to light brown. Head: punctation coarse and dense, distinctly sparser in median dorsal portion; interstices with shallow microsculpture. Eyes moderately small and composed of approximately 50 ommatidia. Pronotum with weakly convex lateral margins in dorsal view; punctation distinctly sparser than that of head; impunctate midline moderately broad; interstices without microsculpture. Elytral punctation dense and somewhat ill-defined. Hind wings completely reduced. Abdomen with fine and dense punctation, that of tergite VII sparser than that of anterior tergites; interstices with shallow microsculpture; posterior margin of tergite VII without palisade fringe. Male. Posterior margin of tergite VIII weakly convex; sternites III–VI unmodified; sternite VII (Fig. 12 A) strongly transverse, with moderately extensive postero-median impression, this impression without setae in the middle, but margined by long and stout black setae, posterior margin weakly concave in the middle; sternite VIII (Fig. 12 B) transverse and weakly asymmetric, with shallow median impression posteriorly, on either side of this impression with several distinctly modified, stout blackish setae, posterior excision slightly asymmetric and somewhat V-shaped; aedeagus as in Figs 12 C, D; ventral process long and moderately broad; dorsal plate with very long, sclerotized apical portion and very short basal portion; internal sac with one long sclerotized spine. Female. Unknown. <b>Comparative notes.</b> The new species resembles <i>L. taiye</i> <b>sp. n.</b> in body size, the shape of the male sternites VII–VIII and the long sclerotized spine in the internal sac of the aedeagus. <i>Lathrobium yipingae</i> is distinguished from <i>L. taiye</i> by the dark brown coloration, the somewhat stouter pronotum, the chaetotaxy of the male sternites VII–VIII and the shape of the ventral process of the aedeagus. <b>Distribution and natural history.</b> The type locality is situated in Shuikou to the south of Jinggangshan, western Jiangxi. The specimen was sifted from leaf litter in a mixed forest at an altitude of 790– 900 m. <b>Etymology.</b> The species is named after Yi-Ping Chen, who collected the type specimen.
