Differential diagnosis

The male of S. tianquanus sp. nov. is morphologically close to that of S. obliquus Shen & Yin, 2020 (Zhejiang) and S. longitrabis (Shaanxi) in the apophysis of antennomere 9 located at anterior half of the segment. It differs from S. obliquus by the much more transverse antennomere 9; and from S. longitrabis

by the larger body size (2.92 mm vs 2.21–2.42 mm), more elongate antennomere 11 and more transverse antennomere 9.

Etymology

The new species is named after Tianquan County, where the type locality of this species is situated.
