Note. The genus includes middle-sized moths and obscure, brown in coloration. The male antennae are bipectinate till to the tip; female antennae are filiform. The forewing facies resembles Darna Walker, 1862 , but usually with four black transverse fasciae (antemedian, median, postmedian, and subterminal fasciae). The tibial spurs are 0-2-4. The larvae are nettle-type.

In the male genitalia, the uncus is bifid and split into lateral processes, but the processes are not balloon-shaped and lack the rows of scales ventrally; the process of costa in valva arise from very base rather than being displaced distally as in Darna and Oxyplax . In the female genitalia, there have a pair of sclerotized plates on the lamella vaginalis either side of the ostium; the signum in ductus bursae is variable, but usually is a scobinate zone or ridge set longitudinally.
