Etymology.

The specific name refers to the type locality, Wugongshan; adjective.

Diagnosis.

The males of the new species are similar to Otacilia daweishan Liu, Xu, Xiao, Yin & Peng, 2019 in having a strong hook-shaped embolus, thick retrolateral tegular apophysis and a finger-like retrolateral tibial apophysis (see Liu et al. 2019: 441, fig. 3B-D), but can be separated from it by the distal tegular apophysis with an oval base (Figs 12D, 13A, B) (vs. with a round base and a mastoid-shaped retrolateral part), the V-shaped sperm duct (Figs 12D, E, 13A, B) (vs. C-shaped) and the retrolateral tibial apophysis with a sharply narrowed basal part (Fig. 12F) (vs. gradually narrowed basal part). The females can be distinguished from O. daweishan (see Liu et al. 2019: 441, fig. 4B, C) by the narrowed median septum (Fig. 14C) (vs. broad, sub-triangular median septum) and the transverse epigynal sclerotized ridge (Fig. 14C) (vs. M-shaped).

Ventral tibial apophysis small, blunt. Sperm duct V-shaped, strongly sclerotized, around base of retrolateral tegular apophysis, distal tegular apophysis and embolus. Retrolateral tegular apophysis clavate, slightly shorter than embolus, apex slightly curved. Distal tegular apophysis triangular, with oval base, covering half of retrolateral tegular apophysis.

Epigynal plate bow-shaped, anteriorly with transverse sclerotized ridge and strongly sclerotized fovea, anteromedially with pair of oval copulatory openings, posteromedially with narrowed median septum. Copulatory ducts, glandular appendages and connecting tubes distinctly visible through integument in intact epigyne. Copulatory ducts broad, slightly sloping, located between copulatory openings and glandular appendages, posteriorly with pair of large, bean-shaped transparent bursae.
