Type material. Holotype ♁, CHINA: Sichuan Province: Guangyuan City, Qingchuan County, Qingxi Town , Yongjiawan Village (32°25′59.52″N, 104°45′35.20″E, 1362 m a.s.l.), 16 Oct. 2020, leg. Zhisheng Zhang. GoogleMaps

Paratypes: 1 ♁ 3 ♀, with same data as holotype GoogleMaps .

Etymology. The species name is derived from the type locality; noun in apposition.

Diagnosis. This new species resembles O. horizon sp. nov. in also having a transverse embolus, but can be recognized by: 1) the smaller retrolateral tibial apophysis (vs large, cf. Fig. 56D View FIGURE 56 and Fig. 34D View FIGURE 34 ), 2) the large dorsal tibial apophysis (vs without dorsal tibial apophysis, cf. Fig. 56D View FIGURE 56 and Fig. 34D View FIGURE 34 ), 3) the copulatory openings extending posteriorly (vs extending anteriorly, cf. Fig. 56E View FIGURE 56 and Fig. 34E View FIGURE 34 ), 4) the thinner copulatory ducts, extending anteriorly (vs extending posteriorly, cf. Fig. 56E View FIGURE 56 and Fig. 34E View FIGURE 34 ), and 5) the distinctly separated connecting tubes (vs close to each other, cf. Fig. 56F View FIGURE 56 and Fig. 34F View FIGURE 34 ).
