Materials Examined
Type material.Holotype ♂, China, Gansu Province, Liangdang County, Heihe Forest Park (34 °07′N, 106 ° 32 ′E), 2 June 2011, leg. Luyu Wang. Paratypes: 6 ♂ and 3 ♀, with same data as for holotype; 7 ♂ and 4 ♀, 1 June 2011, same locality and collector as for holotype; 1 ♂, Anhui Province, Qiyun Mountain (29 ° 48 ′N, 118 °0′E), 19 April 2011, leg. Luyu Wang; 1 ♂, Sichuan Province, Nanjiang County, Micang Mountain (32 ° 43 ′N, 106 ° 51 ′E), 19 May 2013, leg. Zhisheng Zhang.
Etymology
Etymology. The specific name refers to the resemblance of the species to O. stella Kamura, 2004; noun.
Diagnosis
Diagnosis. The new species is similar to O. stella in having a male palpal tibia with two retrolateral apophyses and two epigynal concavities. It differs from O. stella by the following characteristics: 1) BTA (Fig. 4 B) much shorter and smaller; 2) embolus nearly extending to the edge of the cymbium (Figs 3 C, 4 B), whereas short in O. stella; 3) tegulum narrow proximally while broad and rounded in O. stella; 4) CO located in the anterior margin of the membranous windows, while located centrally in O. stella (see Kamura 2004: 88, figs 1–6). The new species also resembles O. vulpes Kamura, 2001 in having a similar RTA, but can be separated from the latter species by: 1) the male palp with a BTA and a RTA, while only with a very short RTA in O. vulpes; and 2) spermathecae nearly parallel to each other (Figs 3 F–G, 4 D–E), while spermathecae posteriorly diverging in O. vulpes (see Kamura 2001: 51, figs 4–7).
