This new species is similar to S. xizangensis Zheng, Lin & Shi, 2013, but differs from the latter in: 1) frontal ridge with carinae nearly parallel;2) horn-like process of pronotum moderately decurved distally with an obtusely rounded apex in profile;3) abbreviated carinae between shoulders indistinct;4) middle lobe of female subgenital plate equal to lateral lobes in length. A classification key to the species in the genus Saussurella is updated.展开更多
