A new species, Carcilia siniaevi sp. n. from China (Guangxi) is described and illustrated. The new species is similar to C. tenuistriata Heller, 1941, but can be distinguished by the outer setose fringe of the metatibial tarsal groove being strongly sinuate, the position of the antennae inserted closer to the rostrum base, the presence of an elongated, forked tooth near the middle of the profemur, the more convex mesosternal process and the straight rostrum. This is the first record of the genus Carcilia in Guangxi Zhuang Autonomous Region.
Andrei A. Legalov (Wed,) studied this question.
