Identification of beetles (Coleoptera)

Hello! Two more beetles caught on 12.03.2016 in a pond (Chernivtsi region):

1. Limnoxenus niger (if the size is about a centimeter).
2. Heterocerus fenestratus.

Please help me with the definition. Tatarstan, Nizhnekamsk district The lighter one was caught in the suburbs of Nizhnekamsk in 2012, and the darker one was also caught in 2012, near the village. Sheremetyevo airport.
Both May beetles, female and male?

Very similar to Melolontha hippocastani

Surroundings of Krasnoyarsk. 2 mm. Is this Sibinia (s. str.) annulifera Pic, 1902?

Ilya, I'm a little confused about your keys. Tychius tectus is shown under the signs-The elytra gaps are covered with scales of the same species, which may differ in color, not in shape, but as a result, you reach the species itself if you follow a different branch, starting with the sign-The elytra gaps (except for the suture) are covered with two types of scales, which clearly differ in shape and usually in size. by color.
Tell me, can this species be completely without such light scattered scales on the elytra and with an almost imperceptible median strip of light scales on the pronotum? Let's say how this species differs from Tychius trivialis Boheman, 1843

I have a tektus from Magadan and a beetle similar to tektus from Yu. The Urals. It is VERY variable, both in color and in the abundance of broad scales. They may not exist at all. That's why it appears in my keys many times in different places.

B.-M. oblong. Prsp. before osn. not narrowed, parallel, slightly rounded on the sides, narrowed to the top. - tectus
Short-oval, wide. Prsp. transverse, rounded narrowed to the top. and main-trivialis

This is what I think a real tektus looks like - http://www.zin.ru/ANIMALIA/COLEOPTERA/imag..._tectus_zab.jpg
only this specimen, unfortunately, is not strong enough, but a few broad scales are clearly visible on the interstices and along the suture, a hint of white stripes on the sides of the pronotum, and a hint of stripes on the odd intervals of the elytra ("banding" is a characteristic feature of American tectuses; in our species, the stripes are less pronounced).

yes, very similar, too small really, but maybe I didn't eat well

for Krasnoyarsk, Legalov did not find any instructions, but judging by the fact that it was found from the Far East to Novosibirsk, I think that this view is quite possible for us ))

The small Tychius is approximately 2.2 mm. Surroundings of Krasnoyarsk. Quite slender.
The head tube is rather long, slightly curved, dark, dark brown at the apex.
Mustache 7 chl., except for the first segment of the mustache black together with the club. Pronotum in uniform light rather narrow scales, at the base a group of white broader scales. Thighs without teeth, black. Shins and feet are brown. Elytra in light evenly spaced narrow scales.
Of the smaller ones, I have melliloti and stephensi, but something doesn't look much like them.

Who is he? Crimea, 1.5 mm

Please tell me the view. Tatarstan, Nizhnekamsk district, near d.Blagodatnaya street. Summer 2013

this is Tychius picirostris (Fabricius, 1787), check again the number of segments in the flagellum) should be 6

100% 6-jointed antennae

Please help me with the beetles.
Thailand, Khao Sok National Park-Krabi Province.


They come to the kitchen in large numbers at night.
They're kind of matte, not shiny, but their feet are shiny.


This one looked like our gravedigger from a distance, but on closer inspection it turned out to be twice as big and at the same time absolutely not shy, you could even touch it - it was so calm. I ate mushrooms on a rotten tree. It was daytime.

It appears to be Encaustes verticalis Delkeskamp, 1933 (Erotylidae).

Very similar to Melolontha hippocastani

Thanks!

1. Limnoxenus niger
2. Heterocerus fenestratus.

Thanks!

If you can't tell me the literature, see its distribution in Ukraine.

This is a whole group of Anomala "grandis" species, or rather, hardly anyone can tell from the photo.

Good afternoon! Can you tell me if I'm right?

H. fenestratus is no doubt everywhere.
I don't know any specific literature on L. niger. But you should also have a regular water lover, especially in the south.

Yeah, cool! rare item

something does not come out to find clear differences between Sibinia unicolor and tibialis. Ilya, what should you pay attention to first, the color or the contours of the elytra on the side?

yes, they are problematic, but unicolor is smaller (1.7-2.1 mm), and tibialis is larger (2.3-3.0 mm), pay attention to the head tube, it has completely different shapes, especially females are well distinguished

Dear colleagues, there is still a question on Trichius, if anyone can - help in determining.

P.S. And once again, please pay attention to my two previous posts. Thanks!

It seems to me fasciatus, but you need to look at the signs.

You were right, this is really fasciatus. Thank you very much!
