Moved from Tachinidae.

Tachinidae: Exoristinae
Tachinidae: Exoristinae...possibly Chetogena sp.

According to the key in Manual of Nearctic Diptera, Chetogena has an apparent extension of M past the bend. According to the revision by Wood (1972) Pseudotachinomyia has only two presutural acrostichals. I can't distinguish Austrophorocera and Parasetigena from this angle.

Moved from Flies.
