Distribution.
Known only from the
type
locality in Guangxi.
Etymology
. The species is named after the
type
locality in Pinglongshan.
Remarks
. The new species is somewhat similar to
L. nigrociliata
Duda
from
Poland
, but it can be separated from the latter by the male cercus rather long, nearly as long as the epandrium. In
L. nigrociliata
, the male cercus is rather short, about 1/2 as long as the epandrium (
Smith, 1969
).
