03AE87CEBD2EFF1BFC8C3FBFFA5DF8E7.taxon	discussion	Remarks. Lepthyphantes zhangmuensis Hu, 2001, more closely related to the genus Himalaphantes by the combination of the following characters: Scape is relatively broad; spermathcae are large and C-shaped; the posterior median plate is robust and covers the stretcher anteriorly; and the stretcher is large. With all of these characters, L. zhangmuensis shows more proximity to the genus Himalaphantes. Hence, it is proposed here as Himalaphantes zhangmuensis (Hu, 2001) comb. nov..

The female of new species resembles that of Megalepthyphantes kronebergi (Tanasevitch, 1989) and M. turkestanicus (Tanasevitch, 1989) in having a similar scape and V-shaped posterior median plate (Figs 184 A – D, 185 A, C; Tanasevitch, 1989, figs 43, 45, 49, 51), but can be distinguished by the spermathecae bean-shaped in M. gongshanensis sp. nov. (Fig. 184 D). The male of the new species can be distinguished from all other congeners by the proximal end of paracymbium with a broad D-shaped projection pointing towards the retrolateral margin of the cymbium (Fig. 185 A). Proximal cymbial apophysis thumb-shaped with blunt end (Fig. 185 B – D). Lamella characteristca curved, with three long and one small branches, distal end serrated (Fig. 185 B, D).	en	Irfan, Muhammad, Zhang, Zhi-Sheng, Peng, Xian-Jin (2022): Survey of Linyphiidae (Arachnida: Araneae) spiders from Yunnan, China.
