Syrphid - Ferdinandea - male

Syrphid - Ferdinandea - Male
Buffalo National River Steel Creek, Newton County, Arkansas, USA
July 10, 2010
I'm a student at the University of Arkansas working on a special problems course identifying the family Syrphidae. All specimens are collected by Dr. Dowlings Lab located at the Department of Entomology at the University of Arkansas.

I'm trying to determine if this is in the genus Eumerus? Also, what species? Thanks for any further help!

Only male among Csalazar's many similar posts
The scutum and abdomen are darker here than in Csalazar's other posts, but it appears to have two notopleural setae and a yellowish arista with black tip that's longer than the antenna.

So like the others, in Shannon (1924), it would go to F. dives...or perhaps F. nigripes, or F. buccata, depending on the number of scutellar setae (which aren't clearly visible in this series). But it seems all three of these species are synonymous to the latter now. See comment here for more details.

Csalazar, have you seen this?

Moved from Eumerus.
