New genus for the guide
Matthias thanks for the id.

 
Empidoid classification
This genus is very close to Drapetis (some consider it a subgenus of Crossopalpus), which is already in the guide (under Empididae, Tachydromiinae). The Tachydromiinae actually belong in the Hybotidae (in case the latter is recognized as a family separate from Empididae). The classification in Bugguide is inconsistent. I don't know how to fix this.

 
moved guides
should i sink Crossopalpus or make it a subgenus of Drapetis? this is done by going to the taxonomy tab and tagging the guides (the option is in blue at the bottom "tag guides") so you could do this yourself if you wished.

 
Thanks
Thanks for explaining to me how to move guide pages. I moved Platypalpus to the Tachydromiinae as well, and created subfamilies for the other unplaced Hybotidae and Empididae genera. Drapetis is now considered a genus separate from Crossopalpus (e.g., see Sinclair & Cumming, 2006) (1). I added this article to the literature section for future reference.

 
thanks
often on bugguide there are two different levels of taxonomy listed under the same page, for instance Tephritoidea is the only superfamily under acalyptratae, the rest are just families. This really conflicts with my systematist sensibilities, but sometimes it is due to historical factors, for instance in the acalyptrates there were once subfamilies but someone complained about the complexity so they were all removed except for tephritoidea.

Organizing the empidoids according to Sinclair & Cumming was the best thing to do with them at the moment.

Crossopalpus
Looks like a Crossopalpus.

Thanks Keith
I saw Wish list for Diptera..., and am trying to get the tiny hard to photograph live flies, hoping it's one of those families.

 
great thanks
the family level classification of the empidoids is somewhat in flux right now, but there's 1 definitely distinct family in the US which we don't have on Bugguide yet- Atelesti*dae. unfortunately, I misidentified the 'asteiid' we had, so the diptera wish list got a little longer.

an empidoid
not sure which.
