Type material.

Holotype ♀ and paratype 1♀ (IZCAS), CHINA: Guizhou Province, Hezhang County, Gaoyan Village, Mt. Wumeng, Tanjiayan Cave (27.20030°N, 104.59103°E, 2135 m), 17.XI.2011, H. Chen & Z. Zha leg.

Etymology.

The specific name is derived from the type locality; adjective.

Diagnosis.

This species is closely related to Pseudonesticus dafangensis sp. n. (see Fig. 71 E–H) and Pseudonesticus spinosus sp. n. (see Fig. 75 E–H). It can be distinguished from these two species by the longer and narrower scape (Sp), the wider distance between the spermathecae (S) and the wider epigynal plate (Ep) (Fig. 76 E–G vs. Figs 71 F–H, 75 F–H). The same combination of characters allows to separate Pseudonesticus wumengensis sp. n. from all the other species of Pseudonesticus .

Description.

Habitus as in Fig. 76 A–C. Carapace pale yellow. Eyes almost absent. Cervical groove and fovea indistinct. Mouthparts pale yellow, darker than the carapace. Sternum pale, heart-shaped, with long setae, posterior corner truncated. Legs and female palps yellowish, tarsi distally darker. Opisthosoma ovoid, pale yellow, covered with long setae.

Epigyne (Fig. 76 D–G): weakly sclerotized. Scape long and narrow, with a blunt tip, protruding outward (Fig. 76E). Spermathecae small, globular, separated by about three diameters (Fig. 76 F–G). Fertilization and copulatory ducts long, coiled into 2.5 loops (Fig. 76G). Vulval pockets wide, close to each others and located around the spermathecae and the fertilization and copulatory ducts (Fig. 76G).

Female (holotype). Total length 2.13. Carapace 0.95 long, 0.77 wide. Opisthosoma 1.38 long, 1.05 wide. Clypeus height 0.20. Sternum 0.60 long, 0.55 wide. Leg measurements: see Appendix A.
