Asteiidae ? - Mumetopia occipitalis

Asteiidae ? - Mumetopia occipitalis
Near Ruraldale, Upshur County, West Virginia, USA
August 13, 2006
Size: 2.3 mm
Thanks to Paul and also to Jan, from the Netherlands, who said that their first thought on seeing this photo was family Asteiidae. Does anyone on this side of the Atlantic recognize this fly? We don't have any Asteiids on BugGuide yet, shall I make a page?

Moved from Mumetopia. Thank you Kevin Barber.

Moved from Asteiidae.

Asteiidae ? - more likely Anthomyzidae
This is not an asteiid. The R2+3 vein is too long even for Leiomyza in which the 3rd costal section is still considerably longer than the 4th and the R4+5 and M veins converge apically (neither condition is apparent here). I am now pretty sure that this is another image of Mumetopia occipitalis (Anthomyzidae). See the other 4 images of M.occipitalis submitted by Graham Montgomery (#96619, 96620, 164915, and especially #147936). Sorry for the loss of a family page.

Kevin, Thanks very much for your ID of this fly!

Moved from Acalyptratae. i have debated this for awhile, i think i'll just go ahead and agree it's Asteiidae based on the reduced wing venation and overall appearance. after i made the family page i realized i probably should have let you do it, Mr. Cresswell, sorry.

My first thought
would be a fly in the family Clusiidae. - Chen

Moved from Flies.
