Unknown diptera - Glyphidops

Moved

Moved from Cactus Flies. It is a Glyphidops. As for the species one will need to examine the specimen to be certain. I think it would be worthwhile since this might be a new record for the Nearctic region. Very interesting find!

Key characters

If you trust the key to Brazilian Neriidae, http://www.scielo.br/scielo.php?pid=S1519-566X2008000100008&script=sci_arttext, this can not be G. flavifrons, but could be another species.

7 (6). Inferior pleurotergite wholly yellow... Glyphidops flavifrons
7. Inferior pleurotergite dark brown... 8

I think your inferior pleurotergite (= katatergite) is dark brown.

The key to genera in Manual of Central American Diptera could lead to Glyphidops but I can't see some details to be sure.

Maybe

Of the two species in Manual of Nearctic Diptera it would be Glyphidops flavifrons but that species was not found in Florida as of the 1980s. The 1965 catalog lists it from Mexico, Arizona, and the neotropical region.

If we assume a range expansion there's no strong reason to suppose the southwestern species moved to Florida as opposed to some other tropical species. I'll have to do more reading. Can you send the fly to an expert? Or take more pictures to help confirm?

G. flavifrons

I had guessed G. flavifrons because it was listed as the only species in the Florida checklist of Neriidae maintained by the Florida State Collection of Arhtrpods in Gainesville. (http://www.fsca-dpi.org/Diptera/Families/Neriidae_FL_Checklist.htm)

I can check with Gary Steck and confirm the ID.

ID?

Did you get an ID from the specimen? This looks darker than G. flavifrons but that could be due to lighting.
