Metadioctria rubida - female

Metadioctria rubida - Female
Los Angeles County, California, USA

Size: 9 mm
Watched this fly mostly on Eriogonum fasciculatum (please see other posts), where prey is relatively abundant.
I could be wrong, but think that its probably in Stenopogoninae .

Metadioctria rubida (female; with a doli? prey). A Southern Calif. endemic and a new genus for BugGuide. Excellent work Harmut!

Thanks, Eric!
Still in Dasypogoninae, at ITIS, Dioctriinae in Geller-Grimm & Artigas?
I just notice that Dioctriini spp. Dicolonus, Dioctria, Eudioctria, are in Stenopogoninae at bugguide, also on Herschel's site based on Fisher & Wilcox. That seems to clear it up - correct me if I'm wrong).
Would you mind taking a look at this one, Leptogaster I think? Found it in the same area.

 
Hartmut,
classification of Asilidae to subfamilies is problematic and has changed often. In fact, there is a new classification due to be published soon: by Torsten Dikow, (Bull. Amer. Mus. Nat. Hist., in press). His PhD phylogenetic studies show 14 subfamilies; the BugGuide Dioctriini (Dicolonus, Dioctria, Eudioctria, Myelaphus and Metadioctria) are in subfamily Dioctriinae. There will be many changes, however, in the relationships among other subfamilies.

I've commented on your nice Leptogaster shot under that image.

 
I appreciate your comments, Eric,
thank you!
Looks like, if I understand correctly, that bugguide should have a page for subfamily Dioctriinae?

 
Excellent
find.
