Maybe it's Eumerus tricolor... I am not home right now.. hope to remember to try to make a more accurate guess tomorrow.
Or maybe someone else does?

What about Eumerus nigrostriatus? It is really hard to tell from a picture - too many of these beautiful flies...

Eyes are separated, while it's a male: sabulonum/tricolor/ovatus. Can't see with certainty if the eyes are hairy (tricolor/ovatus), but it looks like it. Sabulonum may usually have more red on T3. Abdomen looks densely covered with silverish hairs; thorax looks to have a blueish shine. This makes me, at this stage, I'd vote for ovatus.

@ Martin: as far as I know now, nigrostriatus Lambeck, 1973 is a junior synonym of etnensis Van der Goot, 1964 (same with purpurariae Ba?z, 1982. Etnensis male has eyes holoptic and bare.

Any comments... please! I am still studying on Iberian species.... :p

You are right with the synonym! But I am not so sure if the eyes are really separated... I agree it is a male and that the eyes could be dichoptic... I got some spanish Eumerus data if you are interested...

Hi Andre and Martin,

Just a comment on the synonymy stated by Andre, E. nigrostriatus Lambeck is indeed a synonym of E. etnensis Van der Goot. But E. purpureus Baez is a valid species, an endemic of the Canary Isles: Smit, J.T., Fraquinho Aguiar, A.M. & A. Wakeham-Dawson. 2004. The hoverflies (Diptera: Syrphidae) of the Madeira archipelago, Portugal. Dipterists Digest 11(1): 47-82.

But I have no ID yet for the species photographed here... Though I am sure it's not E. ovatus, to elongated and no silvery hairs visible at the tip of the aabdomen...

John

Hi John. I didn't write purpureus (I know that's a valid endemic species), but purpurariae.

Hi Andre,

My fault, I meant E. purpurariae...
Both E. purpurariae and E. purpureus occur on the Canaries and both are mentioned in the paper refered to... I can't help people comming up with those confusing names.. ;)
