possibly Arrhinactia sp. ??? (pe-taxon #15)

This is an interesting and very prolific taxon that might, on the face of it, seem to be unexceptional. But it stands out from the others by having a very peculiar abdomen shape – laterally compressed at the apex with the male terminalia protruding from the most ventral part. The abdominal dusting colour & pattern is also quite distinctive.

EDIT (Monty Wood 26/9/2010): These are all Arrhinactia sp.
