Zametopina wanliae Lin & Li , sp. nov. ( Figs 68 , 69I )

Etymology. The species is named after Ms. Wan Li; noun (name) in genitive case.

Diagnosis. The new species is similar to Z. calceata Simon, 1909 (see Tang et al., 2010) by the similar shape of the retrolateral tibial apophysis and serrated apophysis near the base of the embolus. However, the new species can be distinguished from Z. calceata by having the embolus as long as the bulb, and the embolus is curved (vs. shorter than bulb and straight in Z. calceata ).

Description. Male (holotype). Total length 1.91; carapace 0.99 long, 0.87 wide, opisthosoma 0.92 long, 0.95 wide. Eye sizes and interdistances: AME 0.07, ALE 0.12, PME 0.02, PLE 0.11, AME–AME 0.23, AME–ALE 0.10, PME–PME 0.23, PME–PLE 0.22, AME–PME 0.19, ALE–PLE 0.20. Leg measurements: I 2.54 (0.79, 0.92, 0.42, 0.42), II 2.51 (0.78, 0.89, 0.44, 0.40), III 1.79 (0.57, 0.60, 0.29, 0.33), IV 1.79 (0.60, 0.61, 0.28, 0.30).

Coloration ( Fig. 69I ). Carapace dark brown, with several indentations. Chelicerae, endites and labium dark brown. Sternum brown. Legs I and II brown, others yellow-brown, with sparse spines and black setae. Opisthosoma oval, dark brown, with three spots. Spinnerets yellow-brown.

Palp ( Fig. 68 ). Patella almost as long as tibia. Retrolateral tibial apophysis 1.5 times longer than tibia, terminus bifurcated. Sperm duct at middle of tegulum. Tegulum with a peculiar membranous process, almost oval. Embolus long and coiled, almost as long as bulb, with an apophysis with some small, black denticles near base.

Female. Unknown.

Material examined. Holotype ♂ (IZCAS-Ar44016), Vietnam: Vinh Phuc, Tam Dao National Park, Natural Forest , 10 May 2005, Dinh-Sac Pham leg.

Distribution. Known only from the type locality.
