Figs 37–39
Type material. Holotype ♁, CHINA: Hubei Province: Shennongjia Forestry District, Hongping Town (31°41′41.62″N, 110°25′40.44″E, 1753 m a.s.l.), 24 Oct. 2020, leg. Luyu Wang.
Paratypes: 4 ♀, with same data as holotype.
Etymology. The species name is derived from the type locality; noun in apposition.
Diagnosis. This new species resembles O. triangula Mu, Jin & Zhang, 2022 in having a similarly shaped embolus and spermathecae, but can be recognized by: 1) the absence of a scar on the embolus (vs with scar, cf. Fig. 38B, C and fig. 11B, C in Mu et al. [2022]), 2) the longer retrolateral tibial apophysis, with a slightly curved tip (vs short, not curved, cf. Fig. 38B and fig. 11B in Mu et al. [2022]), 3) the rectangular conductor (vs triangular, cf. Fig. 38C and fig. 11C in Mu et al. [2022]), and 4) the anteriorly wide, posteriorly narrow median septum (vs anteriorly narrow, posteriorly wide, cf. Fig. 38E and fig. 11E in Mu et al. [2022]).
