Figs 1–3, 13
Type material. Holotype ♂ (MHBU), CHINA: Sichuan Province: Mianyang City, Pingwu Co., Baima Town, Wanglang National Nature Reserve, between Baixiong Gully and Zhenbao Bridge (32°59’7.62”N, 104°3’27.12”E, 2638 m a.s.l.), 24.08.2016, leg. L. Wang.
Paratypes: 1♀ (MHBU), with same data as holotype.
Etymology. The specific epithet is derived from the type locality; noun in apposition.
Diagnosis. The new species resembles O. yongjia Mu & Zhang, 2023 in having a similarly shaped femoral apophysis and copulatory duct, but can be recognized by: 1) the retrolateral tibial apophysis with hooked tip, and a small tooth-shaped apophysis near base of retrolateral tibial apophysis (vs slightly curved tip, tooth-shaped apophysis absent, cf. Fig. 2B–D and fig. 56B–D in Mu & Zhang [2023]), 2) embolus with slight median concavity (vs not concaved, cf. Fig. 2C and fig. 56C in Mu & Zhang [2023]), 3) glandular appendage distinct, digitiform (vs absent, cf. Fig. 2F and fig. 56F in Mu & Zhang [2023]), 4) median septum posteriorly wider (vs anteriorly wider, cf. Fig. 2E and fig. 56E in Mu & Zhang [2023]).
