Superficially this species looks much like A viciua , but the
pubescence of the apex of the abdomen at once separates it It
is very much like A pnmi, but that has the punctures of the
abdomen much stronger, the basal joint of the hind tarsi is longer and narrower, and the colour of the tarsal pubescence is entirely
different
