Curculionidae

Rhynchitidae.
Two similar rhinitis diseases that often cause a dispute:
1) Byctiscus populi Linnaeus, 1758. Built: 14.09.1997
2) Poplar tubecover: Byctiscus betulae Linnaeus, 1758. Built: 30.05.2000.
Both beetles are from here: M. O. Lyuberetsky district of okr. der. Torbeevo (found on the same deciduous trees despite their names).

Vasily, you've made a mistake yourself: the birchbark is Byctiscus betulae, and the poplar tree is Byctiscus populi. You have the opposite. I need to fix it...

  Otiorhynchus aurosquamulatus Retowsky
9-13. 06. 2007
NW Caucasus, Adygea,
cr. Azish-Tau, per. Maikopsky, subalpine, h=1800 m
. 9-13.06.2007 A. Safronov leg.
Body length is 9-10 mm.

There are rather 2 species here - the first is marthae Rtt.,
and the second-it is different from the rest of the population, but I refer it to tatarchani Rtt - it is slightly different from the rest of the representatives of this species, although it is known for its high variability

  Curculio elephas Gyll.

Krasnodar Territory, the settlement's surrounding area. Bolshoy Utrish, 12-30. 08. 2012

The length of specimens (with a head tube) is 11 and 10 mm.

lower - female Curculio venosus (Gravenhorst, 1807)
I'm not sure about the upper one either, although it looks similar to elephas

Do you need to post any angles of this top instance to verify the presence of elephas in the Krasnodar Territory?

These species are easily distinguished by their females (the female elephas has a longer head tube than the body, and the female venosus is noticeably shorter), they also differ in the shape of the elytra, and the elephas has thinner and longer legs. Perhaps a good sign - the prong on the rear thighs of the elephant is rectangular, as in the picture on the left - http://coleop123.narod.ru/key/curculioninae/Curculio11.html

Elefas should definitely be in Krasnodarsky because it is available in Adygea and Volgograd (old data).

From the posterolateral prong, it looks like an elefas after all:

If it is found in Adygea and Volgograd, then why is it not listed in the catalog for the fauna of the Russian Federation?

Or is this incorrect data?

Thanks! Yes, it seems that the prong is really straight!
The catalog doesn't list many species, even the ones I catch around my house every day

The prong is best viewed from the inside of the leg, because the bristles located on the hip and prong can interfere (I encountered this problem when I identified venosus/pellitus from YAO, 2 copies. initially identified (looking from the outside) as two species, then found out that one is venosus....
