Topic: Anasimyia lineata (Hoverfly)

Hi Chris,

Not at all sure what you will make of the below or whether you will wish to pursue it further due to potential change soon.  I posted a phoyo on the UK Hoverflies FB group:

I'm a bit puzzled over this one (Cors Ddyga, Pentre Berw, Anglesey - SH46297248) photo'd on 09/06/2019.  I think it is Anasimyia lineata BUT I have just found that on the continent this was renamed to Lejops lineatus and has then again been split into Eurymyia lineata and Erymyia stipata.  Can anyone provide any clarification for me please ??

I would stick with Anasimyia lineata! Gerard Pennards, have you any insights into what is going on!

, is it A.lineata - it has been suggested it may be contract or transfuga as there is no sign of an extended face or orange antennae ??

Roger Morris
no, it is lineata, I think the face is just obscured by the angle as are the antennae

Steve J. McWilliam
Thanks Roger; nice to get confirmation.

Well, what is going on is that this species is placed in a new genus (also in Europe!), which used to be a subgenus. It is like this: In the Nearctic Anasimyia is seen as a subgenus of Lejops, but here in the Palearctic workers tend to see them as a genus. In 2019 Skevington and Locke published their guide on Syrphidae of northeastern North America, in which they found such differences on a genetic level that this species was placed in another genus, so now it is officially called Eurimyia lineata. It was thought to occur in the Nearctic region as well, but they also found that lineata occurs only in the Palearctic region, the one that was called lineata in the Nearctic is nowadays called Eurimyia stipata....

many thanks - that makes life far too complicated so I think I will stick with Anasimyia!

Yes, but when the Red list of European Hoverflies will be published you'll see the name has changed to Eurimyia lineata. The rest of the species is still called Anasimyia though....
