covered with light yellow scales, labial palpus
drooping and covered with grayish scales.
Eye bare; arista bare; ocellar seta proclinate, short or weak; outer vertical seta reduced, indistinguishable from postocular seta; frontal setae descending to level of upper third of parafacial, flanked by irregular row of shorter setae; fronto-orbital plate with short and thin setulae from vertex level to lowermost frontal seta; one reclinate orbital seta; proclinate orbital seta absent; parafacial bare except for a few hairs below lowest frontal seta; arista tapering smoothly to apex; first aristomere short; second aristomere slightly longer than wide; vibrissa stout, inserted above level of lower facial margin; palpus
clavate, slightly bowed on apical third and slightly longer than prementum; lower facial margin slightly projected; genal dilation covered with thin black setulae.
The maxillary palpus
has four segments; the second and third segments are equal, and the last is the longest (Figure 1e).
, and first leg of holotype on microscope slide, SMF cat.
(n = 5) with four segments, all cylindrical with setae, and segment 1 shorter than the others, 0.07-0.09 mm long; segment 2, 0.11-0.13 mm long; segment 3, 0.09 mm long; and segment 4, 0.10-0.12 mm long.
Outer maxillipeds placed nearly longitudinally; merus and ischium fused, a demarcation line sometimes visible between them; palpus
three segmented, carpus slightly longer than subtrapezoidal propodus, dactylus articulated disto-medially on ventral margin of subtrapezoidal propodus, overreaching it considerably.
The morphogenesis of the adult Drosophila mouthparts, the maxillary palpus
and proboscis, requires four Hox genes: labial (lab), Deformed (Dfd), pb, and Sex combs reduced (Scr) [3-7].
Inner face of the third antennal segment dark brown; palpus
yellowish with dark distal region; gena with lower half blackish and upper half pale brown.
