Type material. Holotype male, China, Yunnan Province, Xishuangbana Dai Autonomous Prefecture, Jinghong City, Mengyang Town, Wild Elephant Valley, 22°10′25.68″N, 100°51′56.58″E, alt. 782m, 3 May 2011, Z.X. Li & G.C. Zhou leg. (SWUC). Paratypes: 2 males and 19 females, with same data as holotype (SWUC).

Etymology. The specific name is a Latin adjective, meaning hook-like, and refers to the shape of the lateral apophysis.

Diagnosis. Zoica unciformis sp. nov. is similar to Z. carolinensis (Framenau et al. 2009: 228, figs 5–8), but differs by the pointed basal process of the lateral apophysis, the retrolaterally directed hook-shaped branch and the stout embolus ( Figs 5 A–C, 6D, 6G–H); Heads of spermathecae ovate, stalks of spermathecae short and strong ( Figs 5 D–E, 6E–F).

Description. Males ( Figs 6 B – C) total length 1.96–2.68. Holotype total length 1.96. Prosoma 0.96 long, 0.71 wide; opisthosoma 0.86 long, 0.53 wide. Dorsum of prosoma yellow-brown. Eyes region black. Fovea longitudinal. Cervical groove and radial furrows indistinct. AME 0.04, ALE 0.04, PME 0.08, PLE 0.06; AME– AME 0.01, AME–ALE 0.01, PME–PME 0.02, PME–PLE 0.03. Clypeus height 0.03. Chelicerae elongate, yellowbrown, with three promarginal and two retromarginal teeth. Labium light yellow, longer than wide. Endites light yellow, longer than wide. Sternum light yellow, shield-shaped, with sparse yellow setae. Legs light yellow. Leg measurements: I 2.45 (0.67, 0.83, 0.53, 0.42); II 2.28 (0.64, 0.74, 0.50, 0.40); III 2.09 (0.60, 0.67, 0.48, 0.34); IV 3.10 (0.84, 1.04, 0.77, 0.45). Leg formula: 4123. Opisthosoma oval. Dorsum yellow brown, with distinct scutum and sparse brown hairs. Venter light yellow.

Male pedipalp (5A–C, 6D, 6G–H). Subtegulum located on baso-prolateral side of the bulb. Lateral apophysis with a pointed basal process and a hook-shaped branch retrolaterally pointed. Embolus stout. Conductor wide, membranous, with a pointed end.

Female (paratype, Fig. 6 A) total length 1.99. Prosoma 0.94 long, 0.70 wide; opisthosoma 1.01 long, 0.62 wide. Eye sizes and interdistances: AME 0.04, ALE 0.04, PME 0.07, PLE 0.06; AME–AME 0.02, AME–ALE 0.02, PME–PME 0.03, PME–PLE 0.05. Clypeus height 0.03. Leg measurements: I 2.46 (0.73, 0.84, 0.50, 0.39); II 2.20 (0.64, 0.72, 0.45, 0.39); III 2.00 (0.59, 0.64, 0.46, 0.31); IV 3.10 (0.85, 1.06, 0.74, 0.45). Leg formula: 4123.

Epigyne ( Figs 5 D–E, 6E–F). Copulatory openings located posteriorly, separated by the diameter of the opening. Heads of spermathecae ovate, stalks of spermathecae short and strong.

Distribution. Known only from the type locality in Yunnan, China ( Fig. 7 ).
