It is impossible to identify this leaf beetle. Maybe someone knows what it's called?


In my opinion, the answer should be sought outside of leaf eaters, in my opinion it is not Chrysomelidae

12.08.2009 14:06, Алексей Сажнев

For PG18:

1. Carenochyrus sp. maybe?
2. Lebia (s. str.) menetriesi Ballion, 1869
3. Cymindis picta (Pallas, 1771) и Cymindis lineata (Quensel, 1806)

lebia menetriesi
Cymindis picta with cross

12.08.2009 14:21, omar

It seems to me that this is Dixus, but the view will not be specified

12.08.2009 14:29, Алексей Сажнев

Yes, exactly Dixus sp.

12.08.2009 15:48, scarit

To PG18:
Think 0030 and 0843 - Mylabris calida Pall.

Isn't that Ditomus?

This new name is Ditomus

For akulich-sibiria:

I think you already know, too, but I'll write just in case ))) I asked Mikhail Leontievich-Phytoecia rufiventris Gautier, 1870 - probably not virgula, but Phytoecia rufiventris Gautier, 1870-red belly?

Well, yes, I already know)). I wrote to him. I'm waiting for the answer, yes abdomen (poslediniy segment) red.

By the way this link confused me and ikterika confused.gif http://www.zin.ru/Animalia/Coleoptera/rus/phyictkm.htm

Dmitry thank you for the gold leaf of Agrilus, although I was confused by the lateral keels, which are described as underdeveloped for this species, and in my specimen they are quite well developed, slightly curved and occupy almost 1/3 of the pronotum

12.08.2009 18:53, Алексей Сажнев

But this is already interesting)) because rufiventris has a red abdomen - http://www.zin.ru/animalia/coleoptera/rus/phy_ruf.htm and in virgula it is the end of the abdomen

13.08.2009 11:47, Pleco

Good time of day! Another selection of beetles from the Crimean foothills. Some were already there, but I didn't fully understand (abscesses, say, Mylabris quadripunctata?) shuffle.gif

I don't think so. The calida is twice as large, and so on...

13.08.2009 14:09, Pleco

Doesn't look like Licinus anymore?

13.08.2009 14:23, Pleco

Although yes, 23 is somewhat close to Licinus depressus, and 25 to Licinus punctatulus, although mine has better pronounced ribs on the elytra and punctuation in 2 rows or more, and punctatus in 1 row.

13.08.2009 14:31, scarit

To Pleco:
28-possibly Mylabris smaragdina Gebl. A light spot on the top of the nadkr.Do you have any?

Unfortunately, there is no frown.gif

13.08.2009 14:58, scarit

Most likely, it is Alosimus chalybaeus (Tauscher, 1812). According to the book of Nikolaev and Kolov, it is quite suitable.

Yes, and it is suitable in terms of habitat, Licinus depressus is found in the Crimea on the South Coast and in the mountains, and L. cassideus is found in the foothills, and it is indeed larger

It turns out that this beetle has got too far to the east?
Danilevsky said it was a very "boring view" of nothing interesting..

13.08.2009 17:58, Алексей Сажнев

)))) He says so about many people )))

13.08.2009 18:11, akulich-sibiria

good evening. what a thread on my elephants can be said, there on the last page and a couple of leaf eaters.
1. something from Rhyzophagus, identified as parallelocollis can this species live here? (the crown behind the eyes is longer than the eyes, the 2nd gap above the cr. not expanded or covered by dots, prdns.longer than the width, grooves on the nadkr. developed, weakened towards the lateral edges, the process of the prothorax between the anterior basins is wide and flat)
picture: P1300001_.jpg
picture: P1300002_.jpg
2. Bitoma crenata ? under the bark of a poplar tree
picture: P1300003_.jpg
3. Cerylon with a more complex view, under the fir bark. maybe some thread deplanatum or ferrugineum, according to pirznakam, on some Caucasian species I go outconfused.gif, that we can live?
picture: P1300004_.jpg

13.08.2009 18:20, akulich-sibiria

)))) He says so about many people )))

do you think this is deliberate? smile.gif But do you think this species is valuable to us and whether it is worth collecting for the trail?a year???

13.08.2009 18:41, Алексей Сажнев

Yes, no, not that specifically, just to him as a taxonomist, this species is not interesting )) And so, I think for your edges it is very good, because in general the view is considered more western

13.08.2009 18:58, scarit

Eugene, 2-Bitoma. Cerylon: there are at least 4 types of them in Siberia, so I personally don't risk identifying them from the photo. But C. impressum, C. deplanatum, and C. ferrugineum can be so red-brown.In principle, you can run away by the Determinant of Long-distance beetles.Of the East.
And the" boring view " for M. D. is virgula?

13.08.2009 19:11, akulich-sibiria

Well, that's what he said. Although Makarov's photo surprised him very much, since there is definitely a virgul instead of ikteriki)).
Well, I defined Cerylon by bark beetle predators. For some reason, I have no signs of these species, just in the Far East I have doubts between C. deplanatum and C. ferrugineum

13.08.2009 19:12, akulich-sibiria

Dmitry, do you have any bark beetle collections from the Kemerovo region?

13.08.2009 19:16, scarit

Well, I think it's worth catching. After all my copy of virgula Danilevsky was very surprised

13.08.2009 19:17, scarit

There are bark beetles, but only a few specimens. I didn't catch them on purpose.

13.08.2009 19:24, akulich-sibiria

There are bark beetles, but only a few specimens. I didn't catch them on purpose.

and could you send them to me somehow or if there are not enough of them, then write, I am especially interested in small ones-pityophthorus, pityogenes, carphoborus, hilastes, cryphalus I am especially interested in spruce, cedar and pine

13.08.2009 19:32, scarit

Among those identified are Ips sexdentatus, Scolytus ratzeburgi, and Ips typographus. There seem to be some small ones, we need to look at them.

well, these are too large and ordinary...pine, birch, spruce....it is interesting to look at the little things..and then I have already determined everything for myself, I would like to see from others tongue.gif

13.08.2009 19:52, scarit

Well, I'll keep that in mind!

2-Lebia, I think still turkestanica

To Pleco:
22-Calathus fuscipes
23 - I like it better as Licinus depressus, but not the fact... size I would like to know ...
24-probably Broscus semistriatus
25-Licinus silphoides
