Diagnosis. Males of Phrynarachne huangshanensis can be distinguished from those of P. mammillata by the ratio of the length of the embolus to the length of the embolus base (7:1 in P. huangshanensis vs 10:1 in P. mammillata ), and the ratio of the length of the RTA to the length of the VTA (3:1 in P. huangshanensis vs 2:1 in P. mammillata ). Females can be differentiated by the length to width ratio of the median plate (3:1 in P. huangshanensis vs 5:1 in P. mammillata ), and the V-shaped median plate (vs M-shaped in P. mammillata ). Description. Male (Figs 5A , 9 , 18B ): total length 2.45, carapace 1.10 long, 1.14 wide, dark brown with long setae. Opisthosoma brown in middle, with some tubercles, each with a clavate seta. A pair of white lines from PLE to fovea. Eye sizes and interdistances: ALE 0.09, AME 0.06, PLE 0.07, PME 0.04; ALE-AME 0.05, AME-AME 0.11, PLE-PME 0.13, PME-PME 0.15. Chelicerae brown, with two promarginal teeth and one retromarginal tooth; gnathocoxae, labium dark brown, labium 0.20 long, 0.21 wide. Sternum black. Legs black, femora I and II with dense, varying-sized tubercles, tibiae and metatarsi I, II with pairs of ventral spines (I, tibia 6, metatarsus 6; II, tibia 6, metatarsus 6); femora III, IV with white stripe. Leg measurements: I 3.54 (1.13, 1.23, 0.66, 0.52), II 3.50 (1.18, 1.22, 0.60, 0.50), III 1.69 (0.55, 0.56, 0.26, 0.32), IV 2.08 (0.73, 0.72, 0.28, 0.35). Leg formula: 1234. Opisthosoma dorsally dark brown, each side with 17 tubercles, each with a clavate seta, center with a pair of yellow markings. Male palp (Fig. 9 ). Tibia brown, VTA club-shaped; RTA long, the length ratio of VTA to RTA is 3:1. Cymbium black. Tegulum flat, disk-shaped, with a tegular ridge. Embolus spiral, thin, the length ratio of the embolus to the embolus base is 7:1. Female. See Li et al. (1985) . Distribution. China (Anhui). Notes. The male is described for the first time here.
