Hello to all!

Any chance to identify this one exactly? In the gallery the most similar one seems to be Chrysotoxum elegans.
The size might be estimated from the Episyrphus balteatus on the first pic.

12.7.2009, Austria, Salzburger Land, Schafberg, about 1300m asl

In C. elegans there is another relation of antenna segment length. The key (I gave you the URL in another thread) led me to C. fasciolatum; however, I would like to learn the opinion of a "real" Syrphid expert!

C. fasciolatum is a large (boreo-alpine) species with a longer, more or less kite-shaped abdomen, with the anterior margin of the wing broadly and contrastingly darkened.
This is C. arcuatum.

Thank you both, Sundew for the try and Menno for exact determination! Smile
