Type species: illaudata Turner = attenuata Moore.
The forewing facies is uniform within the genus as
described for the Bornean species below. Veins M2 and M3 of the forewing share a
long common stalk, whereas in other genera they are separate or at most connate.
The male antennae are filiform. The apodemes of the second tergite are large,
paddle-like (Fig 345).
The male genitalia of the type species have the
saccus narrow, acute, the labides dagger-like and the valves finely setose. The
eighth sternite has a central, asymmetrically bifid, strongly sclerotised
The female has a very short ductus and a large
pyriform bursa, the latter containing extensive zones of coarse spining
surrounding a more massive, thorn- like spine.
The genus is completed by A. subteracta Prout
(N.E. Himalaya, Peninsular Malaysia) and A. cuprina Prout (Sri Lanka).
