Figs 3 , 4 , 7B , 8B, C Type materials. Holotype : ♂ (Phu-158), China, Jiangxi Province, Yichun City, Yifeng County, Guanshan National Nature Reserve, 28°32'22.88"N , 114°35'47.00"E , 719 m, 25 February 2023, leg. Ke-ke Liu et al. Paratypes : 1 ♂, 4 ♀, with the same data as holotype (Phu-158); 1 ♀, Donghe Station, 28°33'16.15"N , 114°34'53.72"E , 439 m, other data as previous (Phu-158). Etymology. The specific name derived from the type locality, Guanshan National Nature Reserve; used as a noun in apposition. Diagnosis. The male of the new species is similar to O. mingyueshan sp. nov. and O. wugongshanica Liu, 2020 ( Liu et al. 2020b : 17, fig. 12A, D, E) in having the carapace with broad, dark-brown, mottled markings medially and a clavate retrolateral tegular apophysis, but it can be separated from them by the retrolateral tibial apophysis with thicker apex (vs moderate in O. mingyueshan sp. nov.; thin in O. wugongshanica ) (cf. Fig. 3E, F and Fig. 5E, F and Liu et al. 2020b : 17, fig. 12E, F) and the hook-shaped embolus strongly curved backward (vs crescent-shaped embolus curved forward in O. mingyueshan sp. nov. and in O. wugongshanica ) (cf. Fig. 3D and Fig. 5D and Liu et al. 2020b : 17, fig. 12D). The female resemble those of O. mingyueshan sp. nov., and O. wugongshanica Liu, 2020 ( Liu et al. 2020b : 17, fig. 14C, D) in having the bow and arrow-shaped mark on the epigynal plate, but the new species can be separated from them by having the fovea without a distinct sclerotised transverse anterior margin (vs with a short, sclerotised transverse margin in O. mingyueshan sp. nov. and O. wugongshanica Liu, 2020) (cf. Fig. 4C and Fig. 5C and Liu et al. 2020b : 17, fig. 14C), the spindle shaped median septum (vs trapezoidal in O. mingyueshan sp. nov.; same in O. wugongshanica ) (cf. Fig. 4C and Fig. 6C and Liu et al. 2020b : 17, fig. 14C), the straightly sloping connecting tubes (vs same in O. mingyueshan sp. nov.; curved in O. wugongshanica ) (cf. Fig. 4D and Fig. 6D and Liu et al. 2020b : 17, fig. 14D); and the relatively widely separated spermathecae (vs widely separated in O. mingyueshan sp. nov.; touching in O. wugongshanica ) (cf. Fig. 4D and Fig. 6D and Liu et al. 2020b : 17, fig. 14D). Figure 3.
