Aha (male).

For Liparus, CRW_5047.jpg — (102.76 k) - this is neither multipunctatus nor atomarius. This is Mycetophagus ciscaucasicus, and it also lives in the Mountainous Crimea.
CRW_5049.jpg - this is not" Scaphidema metallicum fucked up, with a red breast", but Scaphidema rousi-it is found in the Caucasus and the Balkans.

hello. Problems with the pill takers. all three beetles, as it seems to me, Byrrhus arietinus identified by DV.
1. Shushensky district, the foothills of Borus, perfectly fits the description
of the Body with parallel sides in the first part. . The ends of the parameres are hooked, shaped like the tip of the penis

2. bereznyak, Krasnoyarsk.
confused by the shape of the tip of the penis. The ends of the parameres are only slightly indented.
picture: РВ120157а.јрд
picture: РВ120158а.јрд
3. also Krasnoyarsk. The shape is more rounded and there is a spot in the middle of the elytra, although for this species it seems that the pattern should be sparse

It seems to me like this:
1 - B. arietinus
2, 3 - B. pustulatus

until I pulled out the edeagus, I had all of them pustulatus, but I'm confused by the shape and length of the paramer. Their outer sides are slightly indented, for pustulatus they are shown straight and their tops do not reach far to the top of the penis.

26.05.2010 9:42, akulich-sibiria

a couple more pieces.
1. as I think Byrrhus pilula

Interesting, interesting... I have a series of Scaphidema from Gelendzhik-much larger than ours and with a red-brown pronotum. So this is most likely Scaphidema rousi? What kind of animal is this ? Who described it and when? I don't find something... confused.gif

Well, here I would agree.
But from Siberia, several other species were described by Chernyshev and Pyutz.

I don't know where to get Pjutz.

Just up to the family: Abscess beetle, some kind of T-shirt. Again, the quality leaves much to be desired, please if you want to get the correct definition-take normal pictures!

Male. And it looks really proscarabaeus. But the photo...... Try to find beetles where elytra are needed for such confused.gifreasons

26.05.2010 18:58, Алексей Сажнев

The female-and the whiskers are a characteristic feature of the species - are curved like this, although there is also violaceus, also with curved whiskers

thank you for Pyutz!! )) Drawings of aedeagus straight to the point I completely agree about arietinus and pustulatus!!!

26.05.2010 19:34, кабул

Yes, thank you .you're probably right . we are currently experiencing a drought and this is their time

26.05.2010 19:35, Fornax13

You're welcome ) It wasn't Putz who did it. This is Mrochkovsky.

And again on the elephants question:
Can you tell me who it is?
Found: 23.09.2000 Here: M. O. Balashikha district, Zheleznodorozhny district, on the grass. L=6mm.

good evening.
1. Is this a male Hydaticus laeviusculus?
picture: РВ140184а.јрд
picture: РВ140185а.јрд
2. 10 mm.The eyes are notched. The claws are equally long. There are very long hairs on the hind legs and legs. The sides of the pronotum are edged. I go to Copelatus, but the length confuses me
picture: РВ140186а.јрд
picture: РВ140187а.јрд
picture: РВ140188а.јрд
3. 11 mm. The legs are red. The abdomen is dark red. The claws are of different lengths. The rear edge of the segments of the hind legs is drawn back. The posterior apical corner of the hind thighs has setae, but no fossa. Pronotum is edged on the sides. There are light dots on the top of the elytra, also along the stroke near the middle. Alternatively-Hybius subaeneus
picture: РВ140189а.јрд
picture: РВ140191а.јрд
picture: РВ140193а.јрд
4. About 4mm. There are dotted rows on the elytra. It is covered with thin rather thick bristles. In addition to them, there are protruding scutes in the rows, I would say thickened ones. On the shins there are grooves for inserting the legs. Alternatively, Porcinolus murinus

3.I haven't seen Ilybius subaeneus, but I advise you to check for I. ater. Very similar indeed.
2. Absolutely not Copelatus. Judging by the sculpture of the top, it is also some kind of Ilybius, or Agabus. I won't guess with the view.

1. H. leviosculus Popp., 1906 and H. laevipennis Thomson, 1867 from Green now synonyms of H. aruspex Clark, 1864. I didn't find it at my place, and it's not possible that it's him. Or maybe it's H. seminiger Deg., 1774. Look at the front claws from the side.

1. About the beetle, which was previously named by me as Copelatus, was wrong, confused by the description of the structure of the hips. The claws seem to be symmetrical and with straight-cut apical segments. The epipleures of the elytra are very narrow, converging in the posterior half at the level of the 2nd sternite. The 1st member of the hind legs is 2 times larger than the 2nd, straight. 10 mm. The intertasic process of the pronotum is simple, not swollen. As an option Eriglenus sp
picture: ater_1.jpg
picture: ater_2.jpg

2. Regarding Ilybius subaeneus, it is indeed similar in description to ater. Confused long. 11-12 mm, for ater no more than 13 mm. As I believe it is a male, it has a weak keel-shaped elevation in the middle of the last sternite, and longitudinal wrinkles along the posterior edge of the sternite
picture: ater.jpg

3. About Hydaticus. The basal band is short, shorter than half the length of the pronotum. there are only two red spots on his forehead. Still more on laeviusculus (= aruspex). They also asked me to show them the claws of my front paws

4. Is this Hydrophorus fuscipes?
