Discussion. The species resembles Phlugiolopsis brevis Xia & Liu, 1993 but differs in the following aspects: basal half of male cerci narrowly expanded, the margins thickened and straight; posterior margin of male subgenital plate almost straight, not excavated; ventral surface of female subgenital plate concave on lateral areas instead of middle area.

Etymology. Named after the type locality.
