20.10.2021 Russia, Leningrad district, near a bank of a swift shallow river
Please, help id the genus at least. The larvae is at hand, I can do supplementary photos.

This is very close to Tabanus cordiger, a typical inhabitant of fast flowing Brooks and rivers. It has large pseudopods and long claws to get a grip. I'll check it again with the Andreeva publication when I'm back at the lab

I checked Andreeva (1990) but there are several other possibilities next to T. cordiger. It is definitely a Tabanus sp., but there are several other species with these long pseudopods. To know for sure you need to check if there are well developed pseudopods at the ventral side of the last (anal) segment or not. You can exclude some other species if you know this. My Russian isn't that good, but I can send you the key for ID if you like.

Atylotus, thank you. As I see it, the last segment has a pair of pseudopods with hooks, although they are smaller than on the previous segment and are located only on the ventral side - on this segment there are no pairs of lateral and dorsal ones. I would be grateful for the key, thanks, although in any case, a specialist diagnosis is necessary for me to be sure.
Is this photo enough to answer your question?

Well, that anal pseuodpod seems to be too large for Tabanus cordiger. I will send you a key with a PM

Eugene, you know this already, but this is still T.cordiger after all

Atylotus, thank you. And here I place the lateral view of the thorax, for it is used in the id key.
