Materials Examined
Type material.Holotype ♂, China, Sichuan Province, Baoxing County, Fengtongzhai Town, Yanjing Village, 30 ° 32.321 ′N, 102 ° 55.273 ′E, 23 May 2015, Zhizhong Gao leg. Paratypes: 2 ♂, 1 ♀, same data as for holotype.
Etymology
Etymology. The species name is derived from the Latin word ‘ ovatus ’, and refers to the oval, egg-shaped bursae; adjective.
Diagnosis
Diagnosis. The new species is similar to O. pseudostella (Fu et al.2014: 488, figs 3 A–G, 4 A–E), but can be distinguished from the latter by: 1) a short E (longer in O. pseudostella); 2) PEA sharp (relatively blunt in O. pseudostella); 3) oval BU located posteriorly (pear-like and located anteriorly in O. pseudostella); 4) CO located centrally in the concavity (anteriorly, concealed by the margin of concavity in O. pseudostella). The new species is also similar to O. acuta sp. nov. (Figs 14–15), but can be distinguished from the latter by: 1) bulb with a sharp PEA prolaterally, directed to 10 o’clock (pointed ventrally in O. acuta sp. nov.); 2) palpal tibia with one broad RTA (with two distinct, thin apophyses with the same length in O. acuta sp. nov.); 3) BU oval, located posteriorly (relatively round, located anteriorly in O. acuta sp. nov.).
