Type material: Holotype male, 1 male, 3 females (all IZCAS) and 1 female ( SMF) paratypes, CHINA: Yunnan Province, Xishuangbana Dai Autonomous Prefecture, Mengla County, Mengyuan Village, Yeniudong Cave (22°13.18’N, 100°59.22’E), 22 December 2006, Shuqiang Li, Guo Zheng leg.

Etymology: The specific name is derived from the Latin unda, meaning “wave”, referring to the wavy shape of the male embolic apophysis; adjective.

Diagnosis: Males of Sinopoda undata sp. nov. can be distinguished from those of other Sinopoda species by 1. uniquely wavy and well developed embolic apophysis, and 2. long and flagelliform embolus ( Figs 8A– E View FIGURES 8 A – H ); females may be recognised by 1. distinct and long anterior rim connecting the two lobal epigynal pockets, and 2. uniquely slender and distinctly bent internal duct system ( Figs 8G–H View FIGURES 8 A – H ).

Description: Male (holotype). Measurements (in mm): PL 7.3, PW 6.3, AW 3.1, PH 5.2, OL 9.7, OW 6.0.

Palp as in diagnosis. Embolus tip extending only slightly beyond embolic apophysis, bent parallel to embolic apophysis, proximal part of embolus freely visible. Sperm duct narrow and only slightly curved in ventral view. RTA with massive basal part, dorsal and ventral RTA ramified only in distal half. Cymbium longer than tibia ( Figs 8A–F View FIGURES 8 A – H ).
