Good afternoon!

Please tell me, and then so boldly identified in the topic of Reports, it really is two males and a female Dytiscus dimidiatus.

It's just that I'm far from an expert in swimmers

Maybe some additional sign is needed - let's do it

Thank you in advance

Potamophilus acuminatus (Fabricius, 1792), probably a late-instar larva.
The length is approximately 11.5 mm.

Replaced the previous image with a more high-contrast one.

Helophorus (Empleurus) nubilus Fabricius, 1776, of which Roman (AGG) has already posted it on page 3.



Washed, photographed. The front shin was broken and still fell off, I had to glue it not very carefully

Stas, great photo, but how did I miss my beetles did you decide to take a picture of them all there? are you really that interested in my beetles?

26.04.2014 13:22, botanque

Thanks!
Nikon Coolpix L820 plus the simplest adaptations from improvised parts, no special equipment. And adequate processing in Photoshop, of course.
By the way, according to my scale, this beetle is medium-sized.

but how did I miss my beetles did you decide to take a picture of them all there?

Roman, a little more Some groups require a complex definition. Until recently, I didn't know the same wrinkles at all, but now I understand enough of the material. And several views really need to be shot for the story, because not all specialists held them in their hands.

I don't mind - it's good when the benefits have gone, I just miss it. but, I really look forward to a joint publication

Helophorus sp., the larva emerging from the egg cocoon. Probably captured on video for the first time.
Screenshots. The video itself will soon be sent to the Zinovsky website.

Hi.

On the advice of dear Dmitricha

Beatle. Plavunets are a family of Dytiscidae. If you lure here a respected botanque, or throw a photo here in this topic: http://molbiol.ru/forums/index.php?showtopic=218370&st=200 - you can expect to determine at least up to the genus.

I brought you an Australian swimmer to show, with the hope of determining!

We have an Inglomaniac hosting service, which requires that all signatures be written in English letters, but does not recognize the Cyrillic alphabet. And I love it when there are captions to photos.

04.04.2015 16:33, Ele-W

Hydaticus sp. from the group of species H. fabricii or similar, male. It is unlikely that anyone will be able to determine up to the view from the photo.

Thank you very much!

That's how to sign it correctly?

Dytiscidae, H. fabricii, Hydaticus sp.

Or remove/add/rearrange something?

04.04.2015 21:14, botanque

05.04.2015 4:46, Ele-W

Better yet: Hydaticus fabricii-group.

OK, I fixed everything everywhere as it should be! Thank you very much.

Hello. Can anyone confirm or refute my guesses? There are two specimens of beetles from the Komi Republic: a male and a female. According to my definitions, it turns out that this is a species of Dytiscus dauricus, previously not found on our territory. Photos of beetles are attached.
Female

Aulacochthebius narentinus (Reitter, 1885)
The beetle's length is 1.16 mm.

The result is rather vague, but still. The first pancake.

In addition, the Saratov specimen of Helophorus uvaroviAngus, 1985, male
