Today I took photos of an unkwown fly. I didn't have idea of the family, but after a few search, I think it is a Psilidae. I find it very close to Chyliza leptogaster. But since I don't know much about this family, is it possible to confirm th ID ?

Thank you in advance.Smile

Thank you for your answer, Darwyn.

With that key, I think it's either C. leptogaster or C. nova, but I think it's difficult to say more with my pictures. I don't even know if it is a male or a female. But I can see that humeri are partly orange and that the orange spot on the front is quite extensive and almost connected to the vertex (as said in this description), so it is maybe closer to C. nova ?

128 in the New World as of 2009. Should be around 140 worldwide depending on how you split.
