Asarkina (Achoanus) hulleyi (Munro)  

Adapted from Munro (1924).

Very like Asarkina, particularly the ericetorum group, but may be distinguished by the absence of a well-defined "collar" of pile on the anterior margin of the dorsum of the thorax. It differs from any form of Asarkina yet recorded by the following features: (a) enlargement of the upper ommatidia of the eyes of the male. The dorsal part of each eye is so inflated anteriorly that, the two organs being contiguous for a considerable length, the frontal triangle is much reduced; (b) by the longer vertical triangle, which is, in the type, three times as long as its base; (c) from known Ethiopian forms, at least, by the vein R4+5 being only gently curved downwards, and not making a decided bend into the cell R4+5. Achoanus resembles Asarkina in the following characters: the frons in the female is narrowed gradually; the buccal cavity is long and narrow; the lateral median sinuosity of the posterior border of the eye is clothed with silvery squamous pile; the abdomen is flat, margined, yellow and transparent, with transverse black bands; the hypopygium in the male is small and asymmetrical.
