This is another neotropical fly from French Guiana. It looks calyptrate and the plumose arista and stripes on the thorax remind me of a sarcophagid but the face is very strangely sculptured and I can't see any hypopleural bristles...

I have no reference papers here, but Richardiidae springs to mind.

I think Paul's mind meant to spring forth Ropalomeridae. What looks like this species appears in the upper photo at http://www.phorid...erica.html

Yep, I think Tony is right ... that looks spot-on.  But next question ... does anyone know *anything* about these flies, beyond their taxonomic position? I have been Googling and I can't see anything much other than they are muscomorphs (I could have guessed that ) and more closely related to sciomyzids ... but nothing on ecology or distribution etc  EDIT: I should add that I have seen adults feeding on rotting fruit.  EDIT2: Seems that all we know about Ropalocerids is that the larvae are found in rotting substrates and the adults are attracted to sweet things. Mine might be a Willistoniella sp., based on the face shape; single pair of marginal scutellars; and the laterally compressed and only slightly curved hind femur. But all corrections are welcome!
