Front yellow, with a narrow brown stripe extending through the ocellar triangle to the frontal suture. Orbits lacking the usual proclinate and reclinate setae, instead with about 1820 long, erect setae on each side in 3 irregular rows; these are about as long as the ocellar setae (slightly shorter posteriorly) and straight for most of their length, the apical 1/5 abruptly bent back. Orbits nearly reaching the frontal suture but only slightly broadened; median frontal area almost bare, with only a few small proclinate setulae near the frontal suture. Face yellow, gena broadly brown immediately below the eye. Antenna with the second segment brown, third segment yellow; arista with about 8 dorsal and 4 ventral rays in addition to the apical fork, and 6 rather long median branches. One moderately strong oral vibrissa present, other oral setulae weaker, about half as long. Clypeus expanded, about as long dorsoventrally as the width of the palps; brown laterally, pale anteriorly. Palp brown, broad, and short, not extending beyond the clypeus, broadest just before middle; one subapical seta slightly longer than the others. Labellum tinged with brown.

Predominantly yellow. Mesonotum on each side with a narrow stripe just inside of the dorsocentral setae, and a broader stripe just outside of the setae, extending the full length. Anepisternum with a dark brown stripe along the dorsal margin; anepimeron with a large brown spot posteroventrally; katepisternum tinged with brown above the posterior seta. Metanotum with two broad brown stripes, in line with the mesonotal stripes. Two pairs of strong dorsocentral setae, the anterior about 2/3 as long as the posterior.

Long and narrow, about 3.5 times as long as wide. Brown markings present at the apex of R1, extending posterior to M; around the r-m and dm-cu crossveins; in an elongate mark on the mid anterior margin, occupying about 1/3 the wing length; and broadly at the apices of R2+3 and R4+5. Otherwise more or less evenly fumose, the background color distinctly yellow in cell C and in cell R3 between the basal spot and the r-m crossvein. The r-m crossvein is well beyond the end of vein R1; penultimate and antepenultimate segments of M equal, about half as long as the last segment. Posterior wing margin between M and CuA1 straight or slightly concave. Dm-cu crossvein nearly perpendicular to long axis of wing. Costal fringe extending about half the distance between apex of R2+3 and R4+5.

Erect setae of orbits short and straight, only slightly longer than the prostrate setulae of the median frons. Proclinate and posterior reclinate setae present but both directed laterally; normally sized, the latter about twice as long as the former.

. Only a few eggs were observed; oviposition vials were changed every week and usually well-developed larvae were already present, indicating a very short period as an egg. The larvae developed on standard Wheeler-Clayton medium with no apparent mortality, but adult survivorship was low, apparently due to refusal to feed on the medium. Consequently the lab-reared adults did not survive to sexual maturity. Development was faster than in other species—total time from egg to adult was 3335 days, with approximately 15 of those spent as a pupa.
