This genus contains a diverse assemblage of species in terms of wing pattern, but shows more consistency in features of the male abdomen. Many species are medium pinkish brown with fine transverse fasciae on the wings as in the next genus, but the principal component of the postmedials tends to be paler than the ground, sometimes whitish, and more continuous.

In the male abdomen, the eighth segment is of the framed corematous type but the frame of the sternite usually supports a shallow pouch that contains a tuft of hair-setae. The uncus is variable, usually slender, though short and stout in omphisalis. The valves have a flimsy cucullus, but are defined by one or two processes basally from the costa and sometimes extending across to the sacculus. The aedeagus is usually straight, relatively narrow, with no cornuti in the small vesica.

The female genitalia have the apodemes of the eighth segment reduced or vestigial, but pockets between them and the ostium are usually shallow compared with those in the next genus. The ductus bursae is narrow, usually uniformly sclerotised. The corpus bursae is pyriform with a slight coil usually in the neck section. Females of omphisalis have the corpus bursae unornamented, but other species have a small scobinate signum.

The genus is found throughout the Old World tropics.
