Alexey, here's another Aphodius. Very similar to A. rectus, but the posterior corners of the pronotum are completely edged!! but you'll also be lucky...That's what confuses me. I have found about 6 different forms of A. rectus ,from almost yellow to completely black. I'm having a hard time with this. I'm leaning towards A. caspius, but I'm not sure. It is very similar to the beetle from page 110, but in this specimen the spot is more clearly bounded, the legs are black (in that one they are brown). Frontal suture with tubercle. The top of the elytra is very slightly pubescent. But the apical spur is anterior. the lower leg is bent inwards.

2 here's another one, leaning towards A. melanostictus...5.5 mm. The platband is slabovyamchatyy. There are red spots on the sides of the pronotum. The feet are brown. And a distinctive pattern on the elytra. The base of the pronotum is bordered, the posterior corners are rounded, without a notch.

3 and here's another one. The casing is rough-grained. On its leading edge, two prongs are very noticeable. A. multiplex can be...

Good evening. Alexey, I've been tinkering with red aphodius. According to three different determinants, I go to different types. There are about 7 species of them in total. And everyone has something that doesn't fit. In green, he entered A. scybalarinus, and in the qualifiers for Wed.But in general, this species was synonymous with A. rufus, so I decided on this option. According to Frolov, I found Chilothorax melanostictus fairly easily. (Thank you for the link). According to A. comma, I stopped at it, only at its incomma form, which is without dots at all.
Here are some more beetles.
1. As I understand it, this is A. (Acrossus) rufipes...??

2. Stopped at A. immundus, does anyone else have teeth on their shoulders..??

3. This is more difficult. 4 mm. The bristles on the shins are of different lengths. There are lighter spots on the sides of the pronotum. The spur on the hind legs is smaller than the 1st segment of the foot. The forehead is without bumps, The legs are dark brown. The shield is slightly extended. I go out for A. pusillus, A. serotinus or A. tomentosus, but I haven't seen them in my eyes. Maybe there will be opinions about this.

1-yes 2-98
percent
3-alas, I don't know anymore

What is not pusillus and not tomentosus is unequivocal. serotinus - maybe, but I can't imagine this species very well (it seems to me that it should be without a light border on the prsp).
Maybe it makes sense to start gluing small beetles? Otherwise, there will be problems with them

I still don't like the comma. A photo of the bristles on the shins would not be superfluous.

In general, there is a check for aphodia b. USSR:

And in a good way, I advise you to download it, if there is any interest in aphodia:
