Figs 22–24
Type material. Holotype ♁, CHINA: Guangxi Zhuang Autonomous Region: Hezhou City, Pinggui district, Guposhan scenic spot (24°37′47.49″N, 111°31′46.89″E, 830 m a.s.l.), 11 May 2021, leg. Yannan Mu.
Paratypes: 3 ♀, with same data as holotype.
Etymology. The specific name is derived from the type locality; noun in apposition.
Diagnosis. This new species resembles O. celata (Fu, Chen & Zhang, 2016) in having a strong retrolateral tibial apophysis and dorsal tibial apophysis, but can be recognized by: 1) the upward bending embolus (vs not bending, cf. Fig. 23C and figs 1D, 2B in Fu et al. [2016]), 2) curved, beak-shaped retrolateral tibial apophysis and dorsal tibial apophysis (vs not curved, cf. Fig. 23B and figs 1E, 2C in Fu et al. [2016]), 3) triangular tegular apophysis (vs semicircular, cf. Fig. 23C and figs 1D, 2B in Fu et al. [2016]), 4) crack-shaped copulatory openings (vs round, cf. Fig. 23E and fig. 2D in Fu et al. [2016]), and 5) the longer connecting tubes (vs short, cf Fig. 23F and figs 1G, 2E in Fu et al. [2016]).
