possibly Hyphantrophaga sp. (Peru)

This keys to Hyphantrophaga sp. but it needs confirming.

EDIT (6/01/2011): Monty has said that this genus is quite anonymous and difficult to split … but they sometimes have hairs on the hind coxa (like Carcelia) and one of my 2 specimens does have this feature so I am tentatively assigning them to Hyphantrophaga.
