Hello to all!
Can anyone tell me, which Parhelophilus this is? Size not more than 1cm. And how can I fix the sex in this genus? The guys don't seem to be holoptic there, as in most of the other syrphid genera...

Thanks a lot, Stephane! I'm surprised. So it's by far the darkest and smallest one of this kind that I've ever seen...

Parhelophilus have yellow antennae and no lustrous facial stripe.
