There are two nutcrackers identified as Dalopius marginatus.
But they are very different. Is this normal or is there an error somewhere?

Here, I came across it. Maybe someone will need it (only with the translation I don't have much):
http://www.coleo-net.de/coleo/texte/mordellidae.htm
There is still such a Variimorda (July 2), I can not understand Variimorda villosa, or what other Variimorda ?
In V. basalis, the pygidium seems to be shorter: http://www.colpolon.biol.uni.wroc.pl/variimorda.htm

Of the mordellids, only a few of the most charismatic animals can be identified from the photo, the rest only with a copy, and even that is not a fact. Well, this one looks like Villosa (as I understand it), but I still can't guarantee it.


In V. basalis, the pygidium seems to be shorter

Still, you need to look at the beetle, the pygidia in females and males are of different lengths.

According to Kryzhanovsky and Reichardt (1976), this is "Cylister oblongus". Now the species is often referred to as Cylister elongatus (Thunberg, 1787) or Platysoma elongatum (Thunberg, 1787). There are no palaearcts at hand. Contact us to clarify

All - South Kazakhstan, Karatau Mountains, Khantagi Gorge, 2-6. VI. 2016

Stenosis. Working Theory-S. fausti Reitter, 1888
picture: Stenosis_fausti.jpg

Gnathosia. The view is unclear. Beetles from the Syr Darya are clearly defined as G. schrenkii (there is a border on the base of the elytra, the border on the base of the pronotum is smoothed in the middle), but the beetles from Karatau do not have a border on the base of the elytra at all, and the border on the base of the pronotum is not smoothed in the middle. This combination of features corresponds to Gnathosia turcomanica Kaszab, but this species is known from 1 specimen. from Turkmenistan. So unlikely in Karatau...
picture: Gnathosia.jpg

Dichillus. Length 3 mm. According to the Turkestan Medvedev's determinant, I enter the subgenus Dichillodontus because there are a number of sharp denticles at the base of the thighs on the underside, but the species then turns out to be D. dentipes G. Medvedev, 1964, which is extremely unlikely...

Mongolia: Ulaanbaatar, VI. 2009, A. Monkhtsetseg leg.

Strange Crypticus. According to Mongolian, I come out on C. quisquilius, but they differ sharply from my Saratov ones by the thick dotted elytra and, especially, the shape of the last segment of the maxillary palps - it is very much expanded (this, unfortunately, is not visible in the photo).

I assume that it can be one of the types described in this paper:
Ren, G., Z. Zheng. 1993. Six new species of the genus Crypticus Latr from northwest of China (Coleoptera: Tenebrionidae) // Journal of Ningxia Agricultural College 14:9-23.

Do you have live beetles?
How can they not sit obediently?
Do you take pictures of water beetles in a special aquarium?

All alive, of course smile.gif
I used to shoot photos in a microaquarium, glued together from old photographic plates (the emulsion was tortured to clean). And then I solved the problem more simply: I shoot in a frosted plastic ice cream box. The side, of course, can not be removed, but it is convenient from above, and the light is immediately diffused.
