Three ocelli in line, of the same size, distant from each other and from eye margin by two ocellus diameters. Eyes large, setose. Pedicel with round sensory organ.

Mediotergite with a few fine setae anteroventrally. Mid and hind tibiae with inner spurs 1.5Χ longer than outer ones. Wing membrane without macrotrichia. Humeral vein at the level of MA. Costa ends beyond tip of R 5, at one­third the length between tips of R 5 and M 1. Sc short, ends at R. R 1 1.3Χ the length of r­m. Length of M3 about equal to length of r­m. Length of M 1 and M 2 fork 4.3Χ the length of M3. Base of M and CuA fork between tip of Sc and M3 base. Legs: Coxae without setae. Hind tibiae with posterior bristles. Abdomen with scattered setae.
