Description

Male (Fig. 5a, b, c), 9 mm. Head (Fig. 5b): frontal vitta dark black, tapered apically approximately 1.5X the width of the ocellar triangle, parafrontal 1/2 as wide as frontal vitta; frontal bristles arise no lower than level of pedicel; antennae black; frontoorbital plate gold turning to black apically; parafacial gold tinged in its entirety; palpi black gray; facial ridge at level of vibrissa with distinct black tinge; gena 1/6 height of head. Thorax (Fig. 5a): yellow-gold when viewed dorsally with four longitudinal black vittae, appearing fused throughout their length; appearing as two indistinct blotches covering 2/3rds of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing yellowish pruinosity over 1/2 its total area; 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars half the length of suabpicals, with these arising almost adjacent to subapical scutellars; legs black. Wings: dark smoky grayish in color, with one bristle arising at the joint between R1 and R2+3; well developped costal spine. Abdomen (Figs 1d, 5a, c): ST1+2 dark velvety black, with slight yellow extending from anterior edge of following tergite, T3, T4, and T5, with bright, yellow bands covering approximately 1/3rd of tergal surface arising at the margins of between the abdominal tergites, these bands wrapping around sides of abdomen but not the underside; bright yellow bands straddling the margin between tergites ST1+2, T3, T4 and over 50% of T5; tergal bands possessing a sharp mid-dorsal peak extending almost to margin of adjacent tergite, in both T3 and T4, but not reaching margin.

Female (Fig. 5d, e, f), 10 mm. Head (Fig. 5e): frontal vitta dark black, parallel sided apically equal to twice the width of the ocellar triangle, prarafrontal 1.5 times as wide as frontal vitta; frontal bristles arise no lower than level of first antennal segment; proclinate orbital bristles present; antennae black; frontoorbital plate entirely gold; parafacial silvery to slightly gold tinged; palpi orange, slightly haired along upper surface forming a hirsute oval along the upper surface of the palps; eyes bearing very short sparse hairs; gena 1/5 height of head. Thorax (Fig. 5d): yellow when viewed dorsally with four longitudinal black vittae, these becoming fused postsuturally, appearing as two indistinct blotches covering just over 1/2 of thorax postsuturally; three postsutural dorsocentral bristles; scutellum bearing yellowish pruinosity over its entirety (occupying 1/2 or more of total area); 3 pairs of scutellar marginal bristles; subapical scutellars widely divergent, lateral scutellars, almost 2/3rds the length of the subapicals, these closer to apex, than to basal scutellars; legs black with silvery sheen. Wings: pale smoky grayish in color, with one bristle arising at the joint between R1 and R2+3. Abdomen (Figs 2c, 5d, f): pointed downward apically so as to appear strongly curved; ST1+2, dark velvety black with very slight infiltration of dull, grayish or bright yellow bands from next segment along posterior margin, T3, T4, and T5 with dull, grayish or bright yellow bands covering at up to 1/2 of tergal surface; bands peaked dorsocentrally creating an apparent dorsocentral stripe extending the length of the abdomen; abdominal bands wrapping around to the underside; bright yellow bands straddling the margin between tergites ST1+2 and T3 with yellow extending up to but not above median marginal bristles on ST1+2, and the anterior margin of T4; T3 and T4 possessing 1 pair of medial discal bristles, insertion point of abdominal bristles punctuated by a black outline appearing as black spots; when viewed dorsally abdomen appearing to have 4 black triangles surrounded by yellow, with 4 black dots between them.

Diagnosis

Small black and gold fly, with 4 prominent black stripes on the thorax, appearing as 2 large thoracic vittae with a golden divider, and a golden scutellum. Female abdomen with a strong down-pointing curve abdominal bands mid-dorsally pointed joining the next segment’s gold band so that 4 small black triangles become apparent on abdomen. The tip of the abomen golden.

Etymology
