Carinae

Both upper and lower crowns have carinae fore and aft but are otherwise smooth and remarkably stout (Fig. 2 E).

The teeth are devoid of carinae, lacking any kind of ornamentation.

Yellow; the antennae fuscous above, also a fuscous cloud at the apex of the anterior wings, the wings hyaline with the nervures black; a spot on the scape within, and three longitudinal stripes on the mesothorax, black; the latter slightly punctured anteriorly; the metathorax smooth and shining, with three oblique carinae on each side, and a small subovate enclosed space in the middle of the disk.
