Wangleg. (CBEE).   Paratypes: 1 female, with same data as holotype ( CBEE);  1 male, Jiangjin District, Dayuandong Scenic Area, 28.89°N, 106.27°E, native forest,  16 July 2011, Z.S. Zhangleg. ( CBEE).   Etymology.The specific name is derived from the Latin adjective ovatus, - a, - um, meaning “oval” referring to the shape of oval posterior parts of spermathecae.   Diagnosis.This new species resembles  Sinopoda triangula Liu, Li & Jäger, 2008( Liu et al. 2008: figs 7A–H) and  S. yaanensis  sp. nov.( Figs 56A–C, 57A–D, 58A–B) in having the distal embolus with triangular apophysis, stout vRTA and spermathecae bulging laterally. The male differs from  S. yaanensisby: palp with embolic tip distinctly shorter than embolic apophysis (with same length in  S. yaanensis); from  S. triangulaby: palp with dRTA slender, pointed distally (blunt in  S. triangula). Female differs from  S. triangulaby: epigyne with lobal septum moderately wide (narrower in  S. triangula); from  S. yaanensis  sp. nov.by: vulva with ends of glandular appendages narrow (distinctly swollen in  S. yaanensis  sp. nov.).   Description.
