Tenth segment sclerotized.

Female (color). Pale brown. Two small spots on vertex, two spots on outer margin of ocellus, transverse band across antennal ledges, series of specks to frontoclypeus and apical 0.66 of clypellus, four spots on scutellum, black. Seventh sternite medially fuscous.

Remarks. This species is closely related to D. montana from which it can be easily distinguished by its long preatrial process of the aedeagus.
