hello. Tell me please.
1. Krasnoyarsk, floodplain meadow, on cereals and compositae
previously defined as Asiorestia ferruginea, but I think it's still A. sublaevis here is a photo of edeagus

2. Western Sayan Mountains, Borus. On the road, on the grass. Something from Nitidulidae, I can't go to the genus, maybe there will be some options? about 2.1 mm. The mace is indistinct and 3-segmented. The process of the prothorax between the basins is sharply descending. Underparts, scutellum, preshitkovaya area of elytra, part of the crown are black.

3. Elephant from the birch tree. Western Sayan Mountains. Borus city. 2 mm. Black, the grooves are very clear,there is no claw part of the foot. On the sides of the pronotum and on the base of the pronotum are rounded few setae. Could it be Anoplus setulosus?

good evening, if you can't help me with this bug.
Zernovka was found in Misha from Uzbekistan. Length 3.2-3.4 mm. The middle of the pronotum base has a double tubercle (not raised and weakly expressed), covered with white hairs.
Pygidium with a longitudinal white stripe in the center. Hind thighs grooved at the bottom, with a pair of teeth spaced at the top. The inner sides of the groove are smooth, without denticles. Pronotum without stripes. The antennae are unfortunately broken off. BUT on the 7th from the bottom you can see some kind of appendage.
Elytra at the base with a triangular spot covered with white hairs. Behind the middle on 4-6 intervals with a spot of white hairs.
Alternatively, Callosobrochus maculatus
