Similar in wing shape and in the possession of a double areole on primaries to Euacidalia Pack. Palpi short; male antennae finely ciliate. In the male hind-legs the tibiae are very broad and long (twice the length of the tibiae in Euacidalia), rather flattened with strong hair pencil, without spurs and projecting apically over the first joint of the tarsi. Tarsi extremely short and attached to the ventral surface of the tibiae.
