Identification of beetles (Coleoptera)

91-100-D. New items-Begichevo, Serpukhov district, Moscow region, 12-21. 06. 2014

What do you think it is ?
Xantholinus?
Body length 7.5 mm.
Saratov region.

Stenistoderus versicolor, you've had it since Dosanga

Yes, what Xantholinus, this is Stenistoderus (=Leptolinus)! For the species, you need to look at the aedeagus, but the version of S. versicolor Solsky, 1872 sensu Ushakov, 1989 is very likely.

Hello! And what is this ground beetle, Carabus violaceus or another? Collection point-dubrava, Belgorod, size 28 mm. Thanks

  Stenistoderus Jacquelin du Val, 1856
Leptoglenus Reitter, 1900

caucasicus (A. Fleischer, 1914)
Caucasus

cephalotes (Kraatz, 1858)
SW Russia;
Europe, Armenia, N Africa, Iran, Iraq, Lebanon, Turkey

nothus (Erichson, 1839)
=brevicornis Latreille,
=sareptanus Stie.
SW Russia;
Algeria, Morocco, Canares, Europe, Iraq, Japan

versicolor (Solsky, 1871)
SW Russia;
Georgia, Tajikistan

Where does this information come from? Doesn't inspire confidence... The genus needs revision, and a lot of names are synonyms...

Information from this publication

This is not a publication, but a compilation manuscript from the Herman and Smetana catalogues. The data is outdated, there are a lot of synonyms and unreliable information... Even the year of S. versicolor's description is incorrect (see Ushakov, 1989).

This is where the beetles end for now , many thanks to everyone for the definition!

Well, staff-Philonthus, if there were other photos and sizes - there would be versions.

106. Labidostomis sp. Male (Chrysomelidae) (L. longimana L. or L. tridentata L., rather, the second one, but you can't tell from this angle).

What angle will help?

The size is about 10..12 mm. And what other angles are needed (for the future)?

Front view, so that the mandibles and platbands are visible. It would also be nice to have the size up to mm and what it was caught on.

Dimensions are needed not about, but exactly, for example, 11.2. And even better-without a belly. On the photos you need: the number of points on the pronotum disk; the shape of the head; dotted lines and grooves of the belly. In addition to the total picture, it would not hurt to have a detailed one. In general, it's easier to show a beetle to someone in Moscow...

There is only such a photo

Size 7-8 mm, what I caught-I don't remember

There are doubts, this is Nicrophorus interruptus before I never came across, or still bald Nicrophorus vespillo

"Bald N. vespillo" does not happen, or this is not it . In the photo, according to modern keys, N. interruptus/fossor. In general, the genus has been in need of revision for a long time, as D. S. Sikes is slowly being revised using modern methods, but most of the Eurasian species have not reached the turn. The band is very heavy for many reasons.

Very even there are vespillos with erased pubescence! It's a pity, the photos do not clearly show whether the back tibia is curved (a sure sign of vespillo), but it seems to be...
