Diagnosis.

Grey dusted black species with yellow face, anterior part of frons, antennae, palpus, fore and mid tibia. Costal vein reaches one-fourth the way between R4 + 5 and M1 + 2.

Description.

Male. Frons longer than wide, yellow on anterior third and black on posterior portion, ocellar triangle black, 2/3 length of frons. Face and gena yellow.

Occiput black. Setae and setulae of head black.

Thorax black with grey microtrichosity, entirely covered with black setulae. Scutellum round triangular with long apical convergent setae and a pair of subapicals 2/3 length of apical ones. Anterior portion of pleura shining, anepisternum and katepisternum partly microtrichose. Chaetotaxy: 2 postpronotal, 1 + 2 notopleural, two postalar and one prescutellar setae. Wing clear with whitish yellow veins. Costal vein reaches one-fourth the length between R4 + 5 and M1 + 2 (Fig. 3). Halter whitish yellow. Legs: fore coxa, fore and mid tibia yellow, all femora and hind tibia black.Abdomen brown with a narrow yellow band on tergites. Male genitalia (Figs 4-5): epandrium black, surstylus brownish yellow with several long setae at base. Apex of surstylus broad and straight. Cercus broad and orthogonally curved, not pointed.

Cerci wide and curved, not narrow, straight and pointed, surstylus with wide and straight apex, not narrowed as in D. sabroskyi  Beschovski, 1977 (Figs 8-9) and not rounded as in D. beschovski  Nartshuk, 2010 (Figs 6-7).
