Etymology. The specific name refers to the type locality, Sangjiu Village; adjective. Diagnosis. The males can be easily distinguished from other Sinodraconarius gen. n. species by the patellar apophysis longer than the tibia vs. shorter than the tibia in other species (Fig. 1A-C ). The females can be easy distinguished from other Sinodraconarius gen. n. species by the epigynal hoods in the center of the epigynal plate vs. anterolaterally in other species (Fig. 2A-B ). Figure 1.
