Stenohya gibba Zhao, Guo & Zhang, 2024 (Ê峰狭伪$) Figs 1.6, 69V, 70T Stenohya gibba Zhao et al., 2024: 106–114, figs 1–6. Diagnosis Male pedipalpal femur with three projections; patella with a small projection medially in the prolateral position; chelal hand concave distally on the dorsal side and with 15–18 triangular apophyses on the dorsal side; the basitarsus and telotarsus of leg I each with a large columnar projection laterally. Female pedipalpal movable chelal finger with 79–87 teeth; female pedipalpal chela (with pedicel) 4.67–4.98 times as long as wide. Material examined Holotype CHINA • ♂; Hunan Province, Suining County, Huangsang Nature Reserve in Nanshan National Park; 26°24′32″ N, 110°05′38″ E; 460 m a.s.l.; 19 Nov. 2023; in leaf litter; Jiaqi Zhao, Jianzhou Sun, Tao Zheng and Songtao Shi leg.; Ps.- MHBU-HN2023111901. Paratypes CHINA • 3 ♂♂, 4 ♀♀; same collection data as for holotype; Ps.- MHBU-HN2023111902–08. Distribution China: Hunan Province. Remarks The most obvious sexual dimorphism of this species is found on the pedipalp and leg I. For the pedipalp: the male pedipalpal trochanter has a process in the median prolateral position and some small frosted projections (female is smooth); the male femur has a curved cylindrical process in the median prolateral position, a projection on the subdistal prolateral surface, and a columnar process adjacent to this projection (female only has a few tubercles prolaterally); the male patella has a small projection in the median prolateral position (female is smooth); the chelal hand is deeply concave on the dorsal side at the distal half, and there are 15–18 triangular apophyses on the dorsal side (female is not concave and smooth). The male leg I is stronger than that of the female, the basitarsus and telotarsus of the male each have a large columnar projection laterally (there are no projections on the female).
