Type material. Holotype male: CHINA: Chongqing City : Jindaoxia Scenic Area , 30.04°N, 106.63°E, native forest, L.Y. Wang leg. (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. Zhang leg. ( 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 56 A–C, 57A–D, 58A–B) in having the distal embolus with triangular apophysis, stout vRTA and spermathecae bulging laterally. The male differs from S. yaanensis by: palp with embolic tip distinctly shorter than embolic apophysis (with same length in S. yaanensis ); from S. triangula by: palp with dRTA slender, pointed distally (blunt in S. triangula ). Female differs from S. triangula by: 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.).
