Chrysotachina cf. braueri & ornata (fg-taxon #21)

The specimens in this taxon group are all metallic tachinids and almost certainly comprise at least 2 taxa. The first is relatively undusted and looks most like Chrysotachina braueri while the other, dusted taxon, looks most like Chrysotachina ornata but I am not convinced that the genitalia match closely enough to be the same species.

EDIT (Monty Wood 26/9/2010): These are clearly Chrysotachina but a species level determination is not possible – it is a big genus.
