Aegilia Walker Gen. rev.

Type species: describens Walker.

This genus has been subordinated to Stictoptera Guenée in the past but its species have numerous distinctive features such as the concave costa to the forewing which gives it a rather characteristic shape.

In the male genitalia the valves bear coremata, a unique feature within the subfamily, a central harpe and a basal process to the valve costa. There are socii on the tegumen in all species except indescribens Prout. The saccus is trilobed and the juxta arcuate as in Stictoptera.

The eighth sternite of the male abdomen has two eversible coremata as in Stictoptera but in addition there is a large, bilobed, interior pocket of corematous membrane with setal bases, supported on a slender Y-shaped sclerotisation (Fig. 170); the pocket often contains a hard substance when dissected, perhaps a pheromone.

In the female genitalia the ductus is sclerotised and the eighth segment is modified in various ways. In Stictoptera the ductus is not sclerotised and the eighth segment is simple. The signum is a central patch of sclerotisation, scobinate, with a central, interior, acute ‘peak’.

According to the accounts of Bell (MS) the Y-shaped cremaster of the pupa is accompanied by six small hooklets rather than four as in Stictoptera.
