A moderate-sized species with narrow frons, striped thorax, yellow abdomen with small black spots dorsolaterally on posterior segments and dorsolateral stripes of dark hair. Wings clear with small but distinct apical black spot. Female. Length 9 mm., of wing 7 mm. Eyes bare, the pattern in life differing from curvipes by having an isolated dark tear-sbaped mark in middle of eye. Head structures as figured for D. pechumani except frons slightly narrower, antennae and palpi slightly more slender. Coloration of pollinose areas as in pechumani; callus and frontoclypeus shiny black, as are tentorial pits. Genae grey, beard sparse, whitish. Antennae colored as in pechumani. All of first and basal third of second palpal segment yellow, remainder black, pollinose, largely pale-haired except at tip, which is black-haired. Mesonotum as in pechuinani except that black shiny areas less extensive, the yellow pollinose areas broader, and scutellum wholly yellow. Pleura as in pechumani. Legs as in pechumani, except hind femora wholly yellow. Wings as in pechumani. Abdomen yellow, the extensive black shiny stripes of pechumani represented by small dark spots dorso- laterally on tergites 2-4, and large black shiny triangles on tergites 5-7. Vestiture is of yellow hairs, except for broad diffuse dorsolateral stripes of black hairs, broadest on tergite 2. There are also small black shiny patches on lateral margins of tergite 5, while the black triangles on tergites 6 and 7 extend to the lateral margins. Beneath the abdomen is clear yel- low and yellow-haired on sternites 2-5, 6 and 7 are dusky, largely black-haired.
