Thanks for the ID help.
Thanks for the ID help. I saw your comment on another contribution, regarding the status of Lejops lineatus in North America. Is my contribution relevant to this taxonomic question? Would my sighting have been classified as L. lineatus in the past?

 
Anasimyia anausis was a synon
Anasimyia anausis was a synonym for Anasimyia lunulata not lineata. Opinions are divided on the validity of anausis but I am following Professor Jeff Skevington who recognises anausis.

 
Thanks. Interesting discussio
Thanks. Interesting discussion of taxonomy. None of these species are reflected at Bugguide as yet, I suppose because the levels below subgenus haven't been satisfactorily parsed.

The genus appears to be poorly represented in Iowa as far as Bugguide records are concerned.

 
They are unable to separate 3
They are unable to separate 3 or 4 females and identification is restricted to males from genitalia. There are probably still more species as yet unrecognised.
In North America, Anasimyia was considered a sub-genus of Lejops but considered a genus in its own right in Europe. There is now a tendency to follow Europe on this issue.
