Habitus as in Fig. 2A. Body brownish black; legs with blackish brown profemora and brown protibiae, basal halves of metafemora light brown, distal halves gradually infuscate; antennae blackish brown to brown. Head nearly orbicular, widest behind eyes; punctation rather fine, weakly umbilicate and very dense, surface matt. All antennomeres longer than broad; antennomeres IV–X of equal length; antennomere I 1.9 times, II 0.9 times, III 1.3 times, XI 1.3 times as long as IV. Maxillary palpus very slender, preapical joint 3.1–3.3 times as long as broad. Pronotum slender, widest in the middle; lateral margins weakly convex in dorsal view; punctation similar to that of head; midline with weakly narrow glossy line. Each elytron with three indistinct, irregular longitudinal and narrowly elevated ridges; macropunctation coarse and partly somewhat serial. Hind wings present. Protarsomeres I–IV distinctly dilated. Abdomen with very fine and dense punctation on tergites III–VIII; posterior margin of tergite VIII (Fig. 1A) weakly convex; interstices with weak microreticulation; posterior margin of tergite VII with palisade fringe. Male. Sternites III–VI unmodified; sternite VII (Fig. 1D) moderately transverse, with pronounced median impression posteriorly, this impression with numerous strongly modified, short and stout black setae, posterior margin broadly and deeply emarginate; sternite VIII (Fig. 1E) convex, posterior excision very deep and U-shaped, its margins furnished with distinctly modified, short and dark setae; aedeagus as in Figs 1F–G, ventral process slender and weakly curved; dorsal plate with long apical portion and very short, weakly sclerotized basal portion; internal sac with pair of shortly sclerotized sclerites. Female. Posterior margin of sternite VIII (Fig. 1B) broadly convex; tergite X of genital segment narrow and rounded apically (Fig. 1C). Comparative notes. Based on the similar chaetotaxy and shape of the male sternites VII–VIII, and the similar structure of the aedeagus, D. hui belongs to the D. malaisei species group and is most similar to D. aqiang. It is distinguished from all other species of the group by the deeper and U-shaped posterior excision of the male sternite VIII and the elongate ventral process of the aedeagus, evenly narrowed to the apex. Externally, D. hui differs from D. aqiang by the somewhat smaller body size and the shorter antenna. For illustrations of D. aqiang see Peng et al. (2017: figure 1) and Figs 2C–E. Distribution and natural history. The type locality is situated in Shimentai to the north of Yingde, northern Guangdong and Sishui Shan to the southeast of Chenzhou, southeast Hunan. The specimens were sifted from leaf litter in forests at an altitude of 150– 650 m. Etymology. The species is dedicated to Mr. Jia-Yao Hu, who is one of the collectors of the type specimens.Published as part of Lin, Xiao-Bin & Peng, Zhong, 2021, Two new species and additional records of mainland Chinese Domene (Coleoptera: Staphylinidae: Paederinae), pp. 444-450 in Zootaxa 5081 (3) on pages 445-447, DOI: 10.11646/zootaxa.5081.3.8, http://zenodo.org/record/577584

Female. Unknown. Comparative notes. Based on the morphology of the aedeagus, this species may be allied to L. hujiayaoi, from which it is distinguished by somewhat smaller body size, the lighter coloration of the body, the chaetotaxy of the male sternite VIII and the nearly straight ventral process of the aedeagus. Lathrobium zhusha is distinguished from the syntopic L. jinxiuense by smaller body size, reddish coloration of the body, the broadly V–shaped posterior excision of the male sternite VIII, by the shape of ventral process and dorsal plate of the aedeagus, as well as the shape of the female tergite VIII. For illustrations of L. hujiayaoi see Peng et al. (2013: figures 2B, 4C–G). For illustrations of L. jinxiuense see Peng et al. (2015: figures 4A, 5). Etymology. The specific name is the Chinese noun “zhusha” (cinnabar) in apposition. It refers to the characteristic color of the body in comparison to the other species known from the Jiuwanshan Nature Reserve.
