Type material. Holotype ♁, CHINA: Sichuan Province: Chengdu City, Chongzhou County, Wenjingjiang Town, Anzihe Conservation Area, Shaoyaogou Protection Station (30°47.577′N, 103°12.683′E, 1641 m a.s.l.), 2 Oct. 2016, leg. Yannan Mu.
Paratypes: 2 ♁ 2 ♀, with same data as holotype; 2 ♁ 6 ♀, same locality, Maliugou (30°46.790′N, 103°13.530′E, 1692 m a.s.l.), 3 Oct. 2016, leg. Luyu Wang.
Etymology. The species name is derived from the type locality; noun in apposition.
Diagnosis. This new species resembles O. longituba Wang, Zhang & Zhang, 2012 in having a similar-shaped embolus, but can be recognized by: 1) the palmate-shaped retrolateral tibial apophysis (vs rectangular, cf. Fig. 47B and fig. 5F in Wang et al. [2012]), 2) the closely situated copulatory openings (vs separated by about one spermatheca diameter, cf. Fig. 47E and fig. 5H in Wang et al. [2012]), and 3) distinctly separated spermathecae (vs close to each other, cf. Fig. 47F and fig. 5G in Wang et al. [2012]).
