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. Gena wider than first flagellomere with a row of black peristomal setulae. Palpus yellow with black setulae. Antenna yellow, first flagellomere round and yellow, arista short pubescent. 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.

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.

The species belongs to subgenus Oedesiella Becker based on the structure of the male genitalia: cerci long and wide apart, surstyli longer than epandrium. 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).
