It differs from L. diospyri Chou & Ma, 1981 as follows: 1) pygofer appendage sinuate, 2) aedeagus processes curved in caudal view, 3) aedeagus processes branched below apex, 4) connective with six lobes, 5) male abdominal apodemes extended to 6th segment.

Etymology. The specific name is derived from that of the type locality.
