Type material. Holotype:GoogleMaps  ♂, CHINA: Hunan Province: Shaoyang City, Chengbu County, Rulin Town   GoogleMaps, Daqiao Village   GoogleMaps, 26°20′26.79″N, 110°16′40.45″E, 527 m a.s.l., 8 November 2017, leg. Guchun Zhou. Paratype: 1♀, same data as holotypeGoogleMaps  .

Etymology. The specific epithet refers to the type locality.

Diagnosis. The new species belongs to the ‘ armatissima  ’ group, and resembles O. komurai ( Yaginuma, 1952)  , but can be distinguished by the following characters: dorsal tibial apophysis leaf-like with pointed end in O. rulinensis  sp. nov. in retrolateral view ( Figs 7GView FIGURE 7, 8CView FIGURE 8), whereas sword-shaped with a blunt end in O. komurai  (see Wang et al. 2012: fig. 3F). Embolus hook-shaped in O. rulinensis  sp. nov. in ventral view ( Figs 7FView FIGURE 7, 8BView FIGURE 8), whereas S-shaped in O. komurai  (see Wang et al. 2012: fig. 3G). Conductor suborbicular in O. rulinensis  sp. nov. in ventral view ( Figs 7GView FIGURE 7, 8CView FIGURE 8), whereas ampullaceous in O. komurai  (see Wang et al. 2012: fig. 3F, G). Bursa oval in O. rulinensis  sp. nov. ( Figs 7DView FIGURE 7, 8EView FIGURE 8), whereas kidney-shaped in O. komurai  (see Wang et al. 2012: fig. 3I). Copulatory opening present ventro-mesally and close to each other in O. rulinensis  sp. nov. ( Figs 7CView FIGURE 7, 8DView FIGURE 8), whereas present ventro-laterally and separated by one-third width of epigynal plate in O. komurai  (see Wang et al. 2012: fig. 3H).
