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...
