of 9th sternum with a horizontal, caudally directed flap, deeply 
bisected to form 2 backward directed spines. Appendages of 9th 
sternum partially membranous, joined at distal ends with transverse 
plate and bearing setae caudo-lateral to transverse plate. Transverse 
plate formed of 2 dorsally directed, C-shaped processes, joined 
ventrally. Just dorsal to juncture, 2 acute antero-lateral processes. 
Apophyses of 9th sternum long and slender. Penis ending posterior¬ 
ly in 2 processes. Postero-ventral 1 large, upward curved, widened 
anteriorly and narrowed posteriorly with sides extending dorsally 
on lateral edge in scoop-like shape. Antero-dorsal process of penis 
more or less cylindrical, arising dorsally within the hollow of the 
ventral process. Dorsal process bearing a duct. 
Female genitalia (Fig. 10D-F): Gonopophyses laterales strongly 
sclerotized, forming a ventral unpaired plate. Strongly sclerotized 
part of bursa copulatrix large with a large postero-dorsal apodeme. 
Immature stages unknown.

Notes: A. megacornis is similar to A. longipennis but differs in the 
shape of the penis and the process of the 9th sternum. Megacornis 
has a much larger ventral spine on the posterior end of the penis 
than does longipennis and the horizontal flap on the process of the 
9th sternum is deeply incised in megacornis but shallowly incised in 
longipennis. 
The female specimens are associated with megacornis because of 
similarities in coloration, size, antennal and wing characteristics and 
distribution. It is possible that they represent a different species, but 
they will be considered as megacornis until shown otherwise.
