Types.

Holotype female, China, Yunnan Province: Gongshan County, Bingzhongluo Township, Chukuai, 27.97928°N, 98.47389°E ,alt. 3725 m, 19 August 2006, Peng Hu (Hu060819). Paratypes: 2 females, Gongshan County, Dulongjiang Township, Maku, 27.68611°N, 98.29660°E, alt. 2097 m, 2 September 2006, Peng Hu (Hu060902).

Etymology.

The species name comes from the Latin adjective “caperatus”, meaning “wrinkled” and referring to parmula with wrinkles in epigyne.

Diagnosis.

Zhezhoulinyphia caperata sp. nov. can be distinguished from Z. denticulata sp. nov. by having the anterior wall of epigyne wider than long, posterior margin without distinct outgrowth (Figs 1 A–C, 2A, B), whereas it is longer than wide, with a big outgrowth in Z. denticulata sp. nov. (Figs 7 A–D, 9 A–D, 10 A–C). Parmula with three transverse wrinkles in new species (Figs 1 A–C, 2A, B), whereas there are seven to twelve in Z. denticulata sp. nov. (Figs 7 A–D, 9 A–D, 10 A–C).

Carapace 1.97 long, 1.54 wide, yellow to reddish, cephalic region slightly elevated with spine like hairs (Fig. 3A, B), fovea, cervical and radial grooves distinct (Fig. 3A); Clypeus 0.48 high. Sternum longer than wide, light yellow, provided with spine-like hairs; labium wider than long; maxillae long, distal end broader, with hairs (Fig. 3B). Chelicerae with 6 promarginal and 3 retromarginal teeth. AER recurved, PER straight, slightly wider (Fig. 3A).

Abdomen 3.38 long, 2.25 wide, oval, grey, mid-dorsally with a black pattern with irregular white patches extending laterally, ventral side pale with irregular white patches (Fig. 3A, B). Epigyne (Figs 1 A–C, 2A, B): Anterior wall of epigyne (AE) wider than long, with wave-like margin posteriorly; copulatory openings present inside atrium; parmula long, extending towards anterior margin first then folding backward, distal part with 3 transverse wrinkles, distal tip with a socket posteriorly. Vulva: posterior median plate broad and cordiform. Copulatory ducts long, arch-shaped; spermathecae L-shaped, present mesally on posterior median plate; fertilization ducts long and extending mesally.
