Syrphidae, but I don't recognise the genus

A new genus?

For that, you would have to ask a syrphid expert, not me! :|

It is a Palpada, and yes, that would mean a new genus for the European continent! Congratulations!
So.. read my PM please...
cheers, André

The North American species are illustrated here, but there are about 100-200 more in South America:

The other genus that crossed my mind was Kertesziomyia, but either way, I think Valter needs to go and catch a specimen! |t

It is surely none of the North American Palpada, and I also first thought of Kertesziomyia, but none of my specimens or the one I could finds pics of have a yellow face. Looking deeper in my collection I found several species of Austalis Thompson 2003 (yes NOT Australis), which are greenish metallic and have a yellow face. Also the space between the eyes is narrow in Kerteszomyia, but broader in Austalis, which also better matches the pictures. The distribution is From New Caledonia, through Australia to Asia, so really far away from the Azores! Very interesting find... now we need some specimens collected!!

I had a look through our Australian Austalis (we have most species here at CNC, including loan material for our Aussie syrphid project). It is certainly similar to some but doesn't really strike me as being in this genus. The gestault to me is more like Kertesziomyia. K. viridis is quite similar overall but the eyes are very widely separated on the unknown species. Like everyone, I look forward to seeing specimens of this some day!
