Comment: This species was previously known only from the type locality in Thailand ( HLAVÁČ et al. 2011 ). The spermatheca of the examined material is similar to that illustrated by PACE (2004) for D. perdensa . There are, however, slight differences in the shape of the median lobe of the aedeagus. Whether these differences are result of an artefact (aedeagus of male paratype deformed?) or attributable to interspecific variation requires clarification based on a revision of the type material.
