view on leftside of vinculum and valva, lateral view inner side of right valva tegumen/uncus, dorsal view aedeagus with vesica everted
Uncus short and narrow, hirsute, somewhat elongated, and distally pointed. Valvae large, broad oval-shaped, and distally rounded; outer surface with long extrusible, hirsute, tube-like coremata; inner sclerotized process short and slender, smooth, strongly bent at its base and with a hook-like tip. Vesica distally with two short, almost straight, parallel cornuti of unequal length fused at their base, originating from a distinct short membraneous papillate appendage.
The species is widespread across most of tropical and subtropical Africa, from the southern Arabian peninsular (Saudi-Arabia, Yemen), Sudan and Eritrea south to the Cape and westwards to Senegal; on Madagascar and the Comoro Islands a different subspecies occurs.
This species had first been synonymized by Hampson (1901: 504) with A. astreus from India; later, however, he accepted A. vitrea as a separate species (Hampson 1920: 527), as did most other authors (Gaede, 1926; Goodger & Watson, 1995). On the basis of the detailed original description, the identity of this taxon has never been in doubt, despite the fact that the type specimen apparently has never been examined.
