Determined here by the "Green" Acidota crenata.

Caught in PTZ, in soil traps.

Confused by the size and color

They write that the size is 5-7 or 6-7 mm.

Mine:
male 7.3-7.5 mm (there is a cut on the penultimate stubble)
female 8.3-8.5 mm (no cuttings)

Compared to the available photos on the Internet, mine are lighter, about the same color as A. subcarinata, which is smaller than 5 mm, there is little information and does not appear in the lists for the European part of Russia.

According to the structure of punctuality and forehead, it is definitely not A. cruentata or A. quadrata.
Yes, they are smaller.

Can A. crenata have this size and light shade ?

What are the newer, special qualifiers for Omaliinae?

Without the material or at least photos, it is difficult to judge. If you still have yes Acidota, then there can only be 2 types specified for the MO. Dimensions without abdomen (according to Zanetti): crenata-2.7-3.6, cruentata-2.0-3.1). Omaliinae can be determined according to acc. tables (Lohse, Szujecki, Zanetti), but, as is often the case, a comparison is desirable. material. There are also Toth tables, but the language is Hungarian...

The species are very similar in appearance.

Mine is the same, accurate to every bristle, MBS resolution, and my squint. Only the structure of punctuality and the edge of the pronotum, as in A. crenata, the color is lighter, the size is larger (for measurement, I put it on a metal ruler under the MBS and looked at the divisions). It's hard to make a mistake with such a special form.

I'll show it to a specialist today. Spread out acceptable can be photographed, if possible.

Please help me deal with this staphylin.
Now we are talking about the photo itself on the zin website and the identifier itself.
One of these sources seems to be wrong.

Here on this photo http://www.zin.ru/Animalia/Coleoptera/imag...ruentata_km.jpg
Acidota cruentata? Before that, I was completely sure of it.

However, in the Green Determinant, in tez 49 (42), on page 113, it is written that "the first segment of the hind leg is much longer than the second". I.e., the genera Acidota and Arpedium should have such a feature. However, in the photo, the first segment is not longer than the second.

In addition, on the outside of the lower leg, you can distinguish distinct spines. This feature, or rather its manifestation, is the key for the neighboring branch.

Need to figure out if this is a typo or something? we are talking about a whole block of births.
