Frontal vitta and upper half of fronto-orbital plate black, lower half of fronto-orbital plate, face, parafacial, gena and postpedicel black with grey pruinosity; pedicel, lower half of arista and palpus yellow. Mesonotum metallic black with a slight blue reflection and with one silver dusted central vitta in front of acrostichals; legs brown; haltere yellowish-white; upper calypter whitish, on outer half white and opaque, lower calypter brownish.

Legs: fore femur with a posterodorsal row of setae, and a complete posteroventral row of setae; fore tibia with a dorsal row of short and strong setae, many setulae on apical half on ventral surface, 1 posterodorsal and 1 posteroventral preapical setae, and anterior surface with a brush-like ctenidium of golden setulae; fore tarsus without modifications in shape or bristling; mid femur with a tubercle at apex of anterodorsal to dorsal surfaces bearing about 3 agglutinated short spines that continue as some 3 dorsal to posterodorsal setae and with 3 oblique setae on dorsal to posterodorsal surfaces, a row of ventral setulae on basal two-thirds, and 1 posterior preapical seta; mid tibia with an anterodorsal comb-like ctenidium of short setulae on basal half and fine setae on apical half, a row of very short and strong setulae, 1 strong posterior seta and 2 strong posteroventral setae on mid third, 1 dorsal and 1 posterodorsal preapical setae and 1 anteroventral, 2 anterior, 1 ventral and 1 posteroventral apical setae; hind femur with an anteroventral row of setae on apical half, an anterodorsal row of setae, 3 dorsal to posterodorsal preapical setae, and a few posteroventral setulae on apical fourth; hind tibia with 8 long anteroventral setae on apical two-thirds, 2 anterodorsal setae on middle third, a dorsal row of short but strong setulae, 1 posterior seta on basal third, 1 on apical third, many long setae on middle third, 1 anterodorsal and 1 dorsal preapical setae, 1 anteroventral, 1 ventral and 2 posteroventral apical setae, a posterior brush-like ctenidium on apical half; hind tarsus with strong setae ventrally. Wing with a uniform covering of microtrichia; dm-cu straight; stem-vein bare before, and with 3 short setulae after, humeral cross-vein on dorsal surface, and ventrally with about 2 short setulae before humeral cross-vein and bare after it; R2+3 bare on dorsal and ventral surfaces; R4+5 bare on dorsal and ventral surfaces; 3 strong setae on basicosta.

Abdomen. With a lateral tuft of setulae on syntergite 1+2; tergite 5 with setae on disc and apically; sternite 1 setulose; posterior margin of sternite 5 concave and with many setae on membrane.
