Medium-sized for cavernicolous trechine beetles, aphaenopsian and depigmented; body elongate, with thin and slender appendages. Head strongly elongate; genae slightly expanded at sides; two pairs of supra-orbital setiferous pores present; frontal furrows short and reduced, ending just behind the level of anterior supraorbital pores; vertex strongly convex; right mandibular tooth bidentate; labial suture completely disappeared; mentum densely pubescent at base of tooth apart from presence of two long setae, base largely and deeply concave; submentum with a row of 15 – 16 setae; antennae thin and long, but not extending over apices of elytra. Propleura visible from above; pronotum cylindrical, distinctly elongated, lateral margins nearly parallel-sided, presence of two pairs of latero-marginal setae (two additional setae present near the anterior seta on each side in the holotype specimen), both of fore and hind angles obtuse. Elytra elongated ovate, with a distinct humeral angle on each side; slightly longer than fore body including mandibles; lateral margins smooth, well-bordered throughout; disc strongly convex, striae noticeable though very weak, almost obsolete; two pairs of dorsal setiferous pores present on the 3 rd stria, preapical pores absent; the humeral group of the marginal umbilicate pores not aggregated, 1 st pore inwardly and backwardly shifted, 5 th and 6 th pores widely spaced. Only 1 st protarsomere modified in male, which is widened and distinctly denticulate inwardly at apex. Ventrite VII with one pair of apical setae in male, whereas two pairs in female.

255087E5FFE9492A1DE9F943FD0A233F.taxon	discussion	Remarks. Xiangxius has the following peculiar characters: the protruding humeral angles on elytra; pubescent mentum; multisetose submentum; narrower pronotum which is as wide as head; and the peculiar elytral chaetotaxy: dorsal and marginal umbilicate pores are large and extraordinarily marked, 1 st pore of the marginal umbilicate series inwardly and backwardly shifted on 6 th striae and at a level behind 3 rd pore, and the 5 th and 6 th pores of the middle group widely spaced, making the distance from 6 th pore to 5 th as long as to 7 th. The character of protruding hemeral angles on elytra is unique among Chinese cave trechines. We hope phylogenetic analysis based on morphological and molecular data would be helpful to determine its position within subterranean trechines in near future.	en	Tian, Mingyi, Huang, Xinglong, Li, Chenliang (2021): Contribution to the knowledge of subterranean ground beetles from eastern Wuling Mountains, China (Coleoptera: Carabidae: Trechinae).

255087E5FFEE492D1DE9FAB3FD0A22C0.taxon	discussion	Remarks. This new genus is probably close to the genus Guizhaphaenops Vigna Taglianti, 1997, especially the subgenus Semiaphaenops Deuve, 1999 since they share the following main characteristics (Vigna Taglianti 1997, Uéno 2000 b): similar body shape with moderately elongated appendages, bidentate right mandibular tooth, completely fused mentum and submentum, base of mentum widely and deeply concave, ventrite VII bisetose and male with only the 1 st protarsomere modified. However, they differ in many character states, e. g.: (1) Only posterior pair of supraorbital pores present in Guizhaphaenopsodes, versus two pairs present in Semiaphaenops, and only the anterior ones present in several species of Guizhaphaenops (s. str.) (Vigna Taglianti 1997, Uéno 2000 b, Uéno & Ran 2004); (2) Fore body more or less pigmented in Guizhaphaenopsodes, versus depigmented in Guizhaphaenops; (3) Antennae sturdier and shorter in Guizhaphaenopsodes, whereas thinner and slenderer in Guizhaphaenops; (4) Pronotum more elongated in Guizhaphaenopsodes than in the latter; and, in particular, (5) Male genitalia shorter and stouter in Guizhaphaenopsodes, versus much longer and thinner in Guizhaphaenops. Furthermore, there is a large gap in distribution between the two genera Guizhaphaenops and Guizhaphaenopsodes: The cave Tangle Dong, locality of Guizhaphaenopsodes, is about 400 km in linear distance from Longyan Dong in Zunyi, Guizhou, the type locality of Guizhaphaenops lipsorum zunyiensis Deuve & Tian, 2018 which is the easternmost locality of Guizhaphaenops species (Deuve & Tian 2018). Guizhaphaenopsodes is also easily separated from Qianaphaenops Uéno, 2000, which is distributed in eastern Guizhou and might be relative to this new genus, by the absence of labial suture (present in the latter genus), the bidentate right mandibular tooth (tridentate in Qianaphaenops), the absence of anterior pair of supraorbital pores (present in Qianaphaenops), only the 1 st protarsomere modified in male (1 st and 2 nd protarsomeres modified in Qianaphaenops) and the absence of the preapical dorsal pores on elytra (present in Qianaphaenops).	en	Tian, Mingyi, Huang, Xinglong, Li, Chenliang (2021): Contribution to the knowledge of subterranean ground beetles from eastern Wuling Mountains, China (Coleoptera: Carabidae: Trechinae).

255087E5FFE149271DE9FF01FC5B2741.taxon	distribution	Distribution. China (Hubei). Known only from a limestone cave near Chunmuyun Town (Fig. 1). The cave Qizimei Dong is at about 4 km from Chunmuyun Town to the west and remains in good natural condition. Its length is unknown. All the beetles were collected in the dark zone not far from the entrance, most found under the stone but one running on the wall of the main passage (Fig. 9 D).	en	Tian, Mingyi, Huang, Xinglong, Li, Chenliang (2021): Contribution to the knowledge of subterranean ground beetles from eastern Wuling Mountains, China (Coleoptera: Carabidae: Trechinae).
