The present paper gives a detailed and illustrated redescription of Entomobrya nigriventris Stach, 1929, and the description of a new species collected from open sand steppe habitat in Hungary. Based on the colour pattern, E. arenaria Winkler, Flórián & Dányi, sp. nov. is close to E. violaceolineata Stach, 1963 but differs from it by the morphology of the labral papillae and the dorsal macrochaetotaxy of the head, Th II, and Abd II–IV. The new species is also characterised by dark ventral body colouration in adult specimens. In this regard, an overview of European Entomobrya species in which the dark ventral side may occur is also provided.
