Differential diagnosis

The male of S. panzhaohuii sp. nov. has antennomere 11 each bearing a wide basal protuberance with two tufts of apical setae, a condition unique within the genus which allows ready identification of the new species.

Etymology

The new species is named after Prof Zhao-Hui Pan, who kindly provided logistic support during our field work in Xizang.
