Dear forum,
I've visited recently the magnific endless expositions of the Naturistorisches Museum Wien (Vienna natural history museum).
Almost all fossils were identified here, but there are some that don't. Usually I don't photograph the latter ones but this one was exciting for me as it belongs to a group of insects (still extant) that I like a lot.
The fossil come from Liaoning, China.
Size is about the same than modern-day Bittacus.
Any suggestion of genus and species, please?
Thanks!
