Asilidae: Asilinae--esp. Efferia and related genera

The subfamily Asilinae of the Asilidae is a bit of a mess. The big question is whether to split, or not, genus Efferia into Pogonioefferia, Albibarbefferia, etc. Herschel Raney's current opinion is to retain Efferia in the broad sense with those as groupings (subgenera? tribes?) under it. (Herschel says they are not officially tribes. Hmm. Maybe we can just place the species in sequence and give the synonyms?) See a brief discussion here:


Some of those "Efferia" have been split out already. Opinions on how to proceed? Does anyone have any authoritative lists to follow?

My take on it
The split taxa wouldn't be tribes- they'd be genera if accepted, subgenera otherwise. Efferia sensu latu would be either the tribe Efferiini, or some other kind of group if the split is accepted. If a name hasn't been published at a particular rank, though, I don't know if it's technically correct to use it.

I would think the simplest solution would be to retain Efferia as a genus, and create No Taxon nodes for the subtaxa (I don't know if it's possible to change a genus to No Taxon, but if possible, that would be the best idea for the existing ones). I don't know whether to call them subgenera or species groups- maybe it's best not to call them anything

 
Sounds good
That made so much sense that I went ahead and did it. I called them "Pogonioefferia group", etc. A couple of images had to be moved, then two guides for genera deleted, with information already there copied to new, no taxon guides. Take a look--I think it makes sense now. Any further contributions anybody can make to the relevant guides would be great.
