Comparative notes. Males of the new species can be readily separated from all known congeners primarily by the stout general habitus, nearly unmodified antennal clubs, and unique form of the aedeagus.

Etymology. The specific name is derived from the type locality, i.e., Maolan National Nature Reserve; adjective.

Distribution. China: Guizhou.
