Holotype: ♀ (IZCAS-Ar41673), China: Hainan: Ledong County, Jianfengling Nature Reserve, Mingfenggu, 18.7417°N, 108.8417°E, 989 m elev., 1.VII.2020, Yunhu Mo leg.

Etymology.

The species is named after Mr Yunhu Mo, who collected the holotype; noun (name) in genitive case.

Diagnosis.

Females of Phrynarachne yunhui sp. nov. are similar to P. mammillata in having the anterior edge and posterior edges of the median plate procurved and the posterior edge with a depression, and in having kidney-shaped spermathecae. However, Phrynarachne yunhui sp. nov. can be distinguished by the oval median plate (vs M-shaped in P. mammillata ) and the broad anterior edge of the spermathecae (vs narrow in P. mammillata ).

Description.

Female (Figs 15 , 19D ): total length 10.04, carapace 3.67 long, 4.44 wide, black.

Chelicerae black, with two promarginal teeth and one retromarginal tooth; Gnathocoxae, labium black, labium 0.83 long, 0.75 wide. Sternum black. Legs black, femora I and II with dense, varying-sized tubercles; tibiae and metatarsi I, II with dense asymmetrical ventral spines (I, tibia 17, metatarsus 41; II, tibia 16, metatarsus 36).
