Alphitobius possibly diaperinus (Panzer, 1797)

Yes, most likely, and the second then Diaclina testudinea (Piller et Mitterpacher, 1783) .

10.10.2009 9:57, Алексей Сажнев

well, yes )

10.10.2009 10:17, Mantispid

Zhezhzhelki. Saratov. Into soil traps. The first length is 14 mm., the second 11 mm.

10.10.2009 10:19, Алексей Сажнев

1. Calathus sp. like, mb Calathus fuscipes
2. Harpalus as decided together yet griseus (Panzer, 1796) )))

The question doesn't have a photo, but I'll ask it anyway:

What is the difference between Calathus cinctus and C. melanocephalus?

10.10.2009 13:06, Mantispid

1. Apparently some kind of harpalus, 15 mm. Saratov. In the forest floor.
2. Dorcadion sareptanum?

10.10.2009 13:07, Алексей Сажнев

2. Yes female sareptanum

10.10.2009 17:59, evk

Zhezhzhelki. Saratov. Into soil traps. The first length is 14 mm, the second 11 mm.

Well Calathus is 99% distinguendus Chaudoir 1846. Why 90%? The two species are almost indistinguishable in appearance (fuscipes and distinguendus); habitually, fuscipes is somewhat broader and stockier, but very relatively so. And 99% because after reviewing the genitals of a couple of hundred copies. from different points of the Volgograd region, not a single fuscipes was found. I think it's the same story in Saratov. To be sure, tear the genitals of males and look at the shape of scleritis in the ext. sac of edeagus according to rabta Vereshchagina; there are no other 100% signs.
About Harpalus-a. There will be a decent resolution image from the bottom, then you can distinguish between rufipes/griseus. And so-adventure smile.gif

The work of Vereshchagina (1984). Briefly - scleritis in the endophallus of the male edeagus.

1-Not harpalus! But completely stumped!!! I'll think about it.
2nd female sareptanus.

About Calathus'a - I agree, although I do not know how to tear genitals frown.gifAnd this is not a male weep.gif
Harpalus there Harpalus griseus Panzer, 1797, I checked by the determinant
, But the second "harpalus" I had as Harpalus rufipes...don't know, maybe a pterostichus?

Which one, to hell with rufipes ... This is something completely different ... Let me think about it ... Saturday today-no time for thoughts tongue.gif smile.gif smile.gif

Well, nothing but the banal Pterostichus melanarius comes to mind here. The legs are very light ... confuses a few. But I can't think of anything else yet.

11.10.2009 8:10, Алексей Сажнев

Well, he himself is some kind of brown, maybe an under-colored copy?

11.10.2009 8:56, evk

Well, there is yes.gifno ground beetle in your area with this appearance, except for Pt. melanarius.

For Mantispid:Harpalus species of our fauna, by definition, cannot have such depressions and folds at the base of the pronotum. Something similar is found in a single species, Harpalus salinus, whose range is slightly grazed by the Baskunchak, but its pronotum is still not narrowed to the base. I mean, if you see a ground beetle with a kind of prsp base, you exclude the genus harpalus immediately smile.gif

It just got mixed up with harpalus trees when I started looking through them yesterday - I saw a strange pronotum, thought what nonsense - and decided to post a photo smile.gif
Oh YES - thank you so much for your HELP shuffle.gif

The first is cupreus, but the second is most likely angusticollis. Look at the front of the chest from the bottom in the middle. If there are no thick thin protruding hairs, then so it is, and if there are such hairs, then still riparius.

Thank you, Evgeny. The prothorax of No. 2 is naked, meaning angusticollis.

Thank you, Evgeny. The prothorax of No. 2 is bare, meaning angusticollis.

His elytra had smooth patches in the middle of the eyespots, which is why I suspected. And, Vasily, specify all the same dimensions - cupreus immediately "falls off"in size! Less trouble.

Thank you, from now on I will (1st-9mm, and the second-6mm).

well, it is changeable according to the drawing, and you need to look at the head and psp for males and females, look at Kabakov
