Hamataliwa wangi Lin & Li , sp. nov. ( Figs 30–31 )

Diagnosis. The male of the new species is similar to H. aurita Zhang, Zhu & Song, 2005 by the shape of the dorsal retrolateral tibial apophysis and strongly coiled and folded embolus, but it differs by having the conductor straight with a 90° bend at the terminus, stick shaped (vs. with flattened terminus, ribbon-like in H. aurita ) and ventro-retrolateral tibial apophysis is significantly longer than the dorsal retrolateral tibial apophysis (vs. ventro-retrolateral tibial apophysis as long as the dorsal retrolateral tibial apophysis in H. aurita ).

Description. Male (holotype, Fig. 31 ). Total length 3.14. Carapace 1.65 long, 1.35 wide; abdomen 1.43 long, 1.20 wide. Carapace brown with white scales. Ocular area greyish black with white scales. Eye measurements: AME 0.08; ALE 0.16; PME 0.14; PLE 0.11; AME–AME 0.11; AME–ALE 0.04; PME–PME 0.25; PME–PLE 0.18. Sternum, chelicera, labium and endites brown, chelicerae same color as carapace, with 2 promarginal teeth and 1 retromarginal tooth. Legs brown with long spines. Leg measurements: I 4.56 (1.37, 1.59, 0.97, 0.63), II 3.61 (1.10, 1.52, 0.61, 0.38), III 3.02 (0.85, 1.16, 0.61, 0.40), IV 3.08 (0.73, 1.23, 0.73, 0.39). Leg formula 1243. Abdomen greyish brown, with yellow-brown pattern, wide anteriorly, sharp caudally, with white stripes.

Palp ( Fig. 30 ). Patellar apophysis small, ventro-retrolateral tibial apophysis digitiform, dorsal retrolateral tibial apophysis blunt, distal part of median apophysis wide; conductor straight, terminus sharp.
