Figures 18 , 19 , 20 , 22 Type material. Holotype : ♂, China, Jiangxi Province, Ji'an City, Xingan County, Zaoshi Village, 27°46'15.63"N , 115°39'38.10"E , 589 m, 7 October 2019, leg. Ke-ke Liu et al. Paratypes : 4 ♂, 1 ♀, 4 juveniles, with same data as holotype. Etymology. The specific name is derived from the type locality, Zaoshi village, which is one of the famous traditional villages; adjective. Diagnosis. The males of the new species are similar to O. yusishanica sp. nov. described above in having a finger-like retrolateral tibial apophysis (Fig. 15C-F ), but can be separated from it by the arc-shaped embolic base (Figs 18D , 19A, B ) (vs. triangular) and the retrolateral tegular apophysis accompanied by the embolus (Figs 18D , 19A, B ) (vs. separated).The females resemble O. yusishanica sp. nov. by having a broad median septum and the thin connecting tubes (Fig. 17C, D ), but can be separated from it by the saddle-shaped copulatory openings (Fig. 20C ) (vs. oval) and the spermathecae separated by approximately 1/3 of the median septum width (Fig. 20D ) (vs. 2/3).
