Chyromyidae

Scutellum appears to be bare on the surface -> Gymnochiromyia, most likely then flavella.

I made this table from different documents to help myself distinguishing Chyromya from Gymnochiromyia :
I think it is a male Chyromya here :

Gut feeling said Chyromya but I could not see any setae on the scutellar surface. Perhaps the original images shed more light. Yann?

Sorry, no better view of the scutellar :-(
For my understanding, the rounded eyes and the swollen femora are not enough for this genus ?
