6. Acontiinae are defined by the scaphium bearing setae, usually in the form of two setal patches; a tympanum with an expanded alula partially concealing the tympanic orifice; and a reduced or nonexistent tympanal hood. A sclerotized crest along the dorsal edge of the sacculus, two SV setae on the first abdominal segment, and general asymmetry of the male genitalia are also typical of the subfamily. In many genera, forewing patterns give the adults the appearance of bird droppings. The male eighth sternite sometimes bears a prominent pair of coremata, and the valva bears a lacuna or thinner area distal to the dorsal boundary of the sacculusof which the dorsal margin is edged with a sclerotized band or crest. The scaphium bears a pair of weak dorsal setal tufts. In female genitalia, a sclerotised band at the distal end of the ductus extends into the corpus bursae, and a pair of strap-like sclerites extends from the ductus into the eighth segment ( Fibiger & Lafontaine 2005).
