Uncus long, narrow, and terminally bifurcate. Valvae large, oval-shaped, distally not rounded; outer surface with extrusible, long and slender tube-like coremata; inner sclerotized process long and almost straight, finely serrated along the dorsal side. Vesica distally with two small, slightly curved, parallel cornuti fused at their base, and with a conical sclerotization at the opening of the ductus ejaculatorius.
Female genitalia
Bursa copulatrix small, without an appendix; ductus bursae narrow, corpus bursae with longitudinal, denticulate signa, bifurcate anteriorly.
Distribution
Central, East, and South Africa; from Zaire and Southern Ethiopia to Angola and South Africa.
Comments
This species is similar to A. catinca and A. shimbaensis, specimens of which have formerly been united under A. bubo (see below). From both species A. bubo can be distinguished by its white hw, and the tuft of scales on the frons as well as the short fw costal areole present in males.
