Type material.

Holotype ♂ (IZCAS): China: Tibet: Zayü: Zhowagoin Township, Sangjiu Village, Mingqi group, 16 km SE of Yakou, N28.72276°, E97.70598°, 3698 m, 1.IX.2014, Jincheng Liu leg. Paratypes: 3♂♂, 3♀♀ (IZCAS): same data as holotype; 3♂♂ (IZCAS): China: Tibet: Zayü: Zhowagoin Township, Xiongjiu Village, N28.60677°, E97.28166°, 1938 m, 29.VIII.2014, Jincheng Liu leg.

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 ).
