Materials Examined
Type material.Holotype ♂, China, Sichuan Province, Miyi County, Baipo Town, 27 ° 7.135 ′N, 101 ° 54.896 ′E, 13 May 2015, Zhizhong Gao leg. Paratypes: 4 ♂, 1 ♀, same data as holotype.
Etymology
Etymology. The species name is derived from the Latin word ‘ auritus ’, and refers to the ear-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 species by: 1) a relatively short E (longer in O. pseudostella); 2) PEA sharp (relatively blunt in O. pseudostella); 3) DTA long, spine-like (shorter, with a wide base and a sharp tip in O. pseudostella); 4) BU ear-shaped (pear-like in O. pseudostella); 5) CO located anteriorly, concealing the margin of the concavity (CO more posterior, located in the center of the concavity in O. pseudostella); 6) short CD (longer in O. pseudostella). The new species is also similar to O. digitata sp. nov. (Fig. 9), but can be distinguished from the latter species by: 1) palp with two tibial apophyses (only one in O. digitata sp. nov.); 2) PEA long, spine-like (relatively shorter, triangular in O. digitata sp. nov.); 3) TA antero-retrolaterally located, small (larger in O. digitata sp. nov.).
