Check the grinder for Lasioderma M. B. thoracicum

Please tell me about Hydrophilus
Water lovers A couple of individuals raises several doubts.
here is this individual I understand Hydrophilus aterrimus because the trough is pronounced
picture: BB66BD7No0w.jpg
picture: nWGqRwLGgOs.jpg

but these two raised doubts,
picture: OqEbW_ya46M.jpg
picture: kWdsYgyhZts.jpg

and this one
picture: D_kQzX9SahQ.jpg
picture: IlpkD6Qmn14.jpg

their groove is not very pronounced, maybe Hydrophilus piceus?
but I'm not sure if it has a pit in the front of the keel? the photo on the Internet is not particularly clear.
and they are all about the same size, 4cm
. the roof of the abdomen is not particularly noticeable, maybe the 3rd is more acute.
caught in the Kaluga region.
According to zin, it turns out that two species of piceus and aterrimus can live out of the big ones.
and in general, I got confused in the last two, they don't really fit the descriptions of piseus, but the depression on the keel doesn't look like aterrimus.

Before the genus is correct, but before the species is difficult.

ground beetle resembles Cardioderus chloroticus

Have you seen him?" At least in a good photo? I take it not...

Yes, right here: http://molbiol.ru/forums/index.php?showtop...ndpost&p=952964
Alexey's photo is certainly not so hot... but what don't you like? Give a comment, pliz!

14.11.2019 9:53, stierlyz

I really like this photo! But you didn't bother to notice, for example, such a detail as the absence of punctuation on the pronotum disk. But in a ground beetle from the Saratov region, the pronotum is completely covered with large dots.

Yes, Dear Andrey, if there is a dotted line, it is very gentle and almost invisible. And the shape of the pronotum (checked) does not match. I admit I'm wrong, this isn't Cardioderus. But 100% I didn't claim it

help with the definition of Parabolitobius ? 8 mm

Apparently, P. dimidiatus (Reitter, 1888) (Megacronus), described from Z.Of the Caucasus: https://www.biodiversitylibrary.org/page/11...ge/171/mode/1up

Yes, Oxytelus. What size is it? Similar to migrator.

Hello everyone Long time no see. smile.gif
Dacha in the upper reaches of the Matsesta River, forest, administrative and urban district of Sochi. The beetle was actively harassed by Plagiolepis pigmea ants, most likely consumed by much more important matters on fatshedera flowers.
The length of this bug is approximately 4 mm. There was one. Mid-October.

Thank you in advance. It was stressful there with the beetles.
But these staphylins ran around at night. One is twice as large as the other - about one and a half and three centimeters.

Not morsitans, like T. eppelsheimianus this thing is called. Check it out.

But not really. What color is it if you wash it?

cleaner did not become

24.11.2019 16:56, Fornax13

it didn't get any cleaner

but not blue like the falcifer? In eppelsheimianus, the head is noticeably expanded posteriorly. In general, the genitals should be looked at in this group.

24.11.2019 22:43, stierlyz

Except for eppelsh. there are simply no other species with single-colored legs.

25.11.2019 4:07, Fornax13

Maybe. However, the beetle in the photo is quite different from the Georgian eppelsheimianus.

Alexey! Check the ground beetle for Curtonotus cribricollis. Probably an under-colored copy.

How is it different? More matte and light? This photo is like this.
But if the beetles from Georgia differ in the shape of the head, they should be compared with the North Caucasian ones. Maybe there is a different taxon in Georgia, for example, subspecies.

Here is the shape of the head/prsp. and differ. And they correspond quite well to eppelsheimianus, at least in the understanding of Quaffe, including the genitals.
