IdentificationA medium-small moth (2.0 - 2.6 cm wingspan) with broad wings. Forewings with a small dark basal patch followed by a light brown band and a paler brown antemedian line. Median band dark brown or dark red-brown, twice as wide at costa as at lower margin, strongly toothed on the outer edge midway, and upper half usually divided by a paler brown insert containing a small dark discal dot. Postmedian area light grey or tan, almost white; shading to brown along the outer margin, and with a irregular dark patch on the costa and a larger poorly defined dark patch in the upper half of the outer margin.
