Type material. Holotype female and 1 female paratype, CHINA: Sichuan, Luding County, Yajiageng (29.84°N, 102.97°E, Alt. 3055m), 14 October, 2005, Xiufeng Zhang and Xiang Xu leg.; 1 female paratype, CHINA: Sichuan, Luding County, Moxi Town (29.41°N, 102.06°E), at 41 km on the Road of Moyu, 20 July 2004, Lihong Tu leg.
Etymology. The specific name is a Latin adjective, meaning “flat” and referring to the shape of the epigynum.
Diagnosis. The females of this new species can be distinguished from those of W. chikunii (Oi, 1979) and W. yunnan Yang, Zhu & Song, 2006 by the copulatory openings situated on the dorsal epigynum. The females of this new species can also be separated from that of W. contortipes (Karsch, 1881) by the different shape of the epigynum. The epigynum of this new species lacks a septum and is quite different from that of W. yele (Hormiga, 2008) .
Description. Female. Total length 5.80–6.14. Holotype total length 5.8, cephalothorax 2.3 long, 1.9 wide, 1.5 high; abdomen 4.4 long, 2.9 wide, 2.9 high. AME diameter 0.18. ALE 1.14, PME 1.0, PLE 1.14 times AME diameter. AME separation 0.5 times their diameter, PME separation 0.36 times their diameter. AME- ALE separation 0.57 times AME diameter, PME-PLE separation 0.86 times PME diameter. Clypeus height 1.14 times AME diameter. Sternum 1.35 long, 1.30 wide, with distal end sharp. Labium much wider than long. Chelicerae with 4 prolateral and 3 retrolateral teeth ( Fig. 11 View FIGURES 9 – 16 ). Cheliceral stridulatory striae absent. Legs with brown annuli. Femora I–II with 2 dorsal setae and 1 prolateral seta. Femur III–IV with 1 or 2 dorsal setae. Patellae I–IV with 2 dorsal setae at the base and distally respectively. Tibiae I–IV and metatarsi I-IV with numerous setae. Metatarsi I–IV with 1 trichobothrium dorsally and Tm I 0.28. Lengths of legs: I 8.8 (2.4+3.0+2.0+1.4), II 7.8 (2.2+2.6+1.8+1.2), III 6.1 (1.8+2.0+1.3+1.0), IV 7.4 (2.2+2.4+1.7+1.1). Leg formula: I, II, IV, III. Femur I 1.11 times length of cephalothorax. Abdomen oval, dorsum with brown and silvery patterns ( Figs 9–10 View FIGURES 9 – 16 ).
Epigynum flat. From lateral and ventral views, dorsal plate of epigynum invisible ( Figs 12–13 View FIGURES 9 – 16 ). From dorsal view, dorsal plate and ventral plate of epigynum completely fused posteriorly and copulatory openings distinct ( Fig. 14 View FIGURES 9 – 16 ). Spermathecae fist–shaped. Copulatory ducts with 1 strong turn mesally. Fertilization ducts oriented mesally.
Male. Unknown.
Distribution. Only known from the holotype and paratype localities (Fig. 30).
Remarks: We place this species in Weintrauboa based on the molecular analysis of Wang et al. (2008), where it was cited as “sp3”.
