N. flavipalpis has peculiar dark spots on the tergites. This is
N. pratensis or
N. croceiventris subsp.
lindneri (I hope there aren't still more similar species in the Ukraine). To discriminate between them, we need a frontal view of the head (in
N. pratesis the area below the antennae between eye and rostrum is yellow, in the other species black). Also the pattern of tergites differs, which is hardly recognizable in the pictures.
If you could read Dutch, you would enjoy the key by Peeters & Oosterbroek (
http://ccw.natura..._2013d.pdf). It is recommendable in any case, because the excellent illustrations explain a lot.
