title: Phylogenetic analysis of Endonura Cassagnau, 1979 (Collembola, Neanuridae, Neanurinae), including descriptions of four new species
abstract: With 54 described species, Endonura is one of the most species-rich genera of the Neanurinae. The taxon is characterised by the presence of 0–2 ocelli, separate tubercles Di and De with the non-crossed type of chaetotaxy on the head, and two or three tubercles on the fifth abdominal tergite. Four new species from the Crimea and the Caucasian region have been described based on adult specimens: Endonura armeniaca sp. nov. , E. cochlearifera sp. nov. , E. crimica sp. nov. , and E. duplex sp. nov.
