Type material.

Holotype ♂ (IZCAS): China: Tibet: Zayü: Zhowagoin Township, Muruo Village, Gaoshan Mountain pasture, N28.62049°, E98.05035°, 4347 m, 5.IX.2014, Jincheng Liu leg. Paratypes: 5♂♂, 3♀♀ (IZCAS): same data as holotype; 1♂, 5♀♀ (IZCAS): China: Tibet: Zayü: Zhowagoin Township, Muruo Village, Qimala Yakou, N28.62049°, E98.05035°, 4657 m, 2.IX.2014, Jincheng Liu leg.

Etymology.

The specific name refers to the type locality, Muruo Village; adjective.

Diagnosis.

The males of the new species are similar to these of S. sangjiuensis sp. n. by having a ventral branch of the patellar apophysis that is larger than the dorsal branch but can be easily distinguished from S. sangjiuensis sp. n. by the apex of conductor being straight vs. bent in S. sangjiuensis sp. n. (Figs 1A-C , 5A-C ). The females of the new species are similar to S. sangjiuensis sp. n. by the apex of septum tapering but can be easily distinguished from by having the hoods and the head of the receptacles located anteriorly rather than medially (Figs 2A-B , 6A-B ).
