The diagnosis of the genus has been presented in Schmidt (2006a).The diagnostic characters in adults are as follows: labial palpus very short, curved, with terminal segment very small, antenna in male bipectinated, forewing with two areoles, underneath more or less uniformly coloured.
Male
genitalia with tegumen bearing sclerotised lateral arms, valvae with costa projecting in an apical process and with basal projection, vinculum with distinct saccus, juxta with lateral papillae, calcar absent. Female genitalia with corpus bursae asymmetrical (with the exception of one Australian species), medium-sized to large, membranous, with a small diverticulum, signum in most species present. The ventral surface of the seventh abdominal segment in females is rough, often with a pair of distinct “pockets” or rounded depressions.
