Dungeraphorura, a new genus of Onychiuridae (Collembola) from East Palaearctic

Abstract

Dungeraphorura yaruna sp. n. is described from Transbaikalian region (Russia: Siberia). Dungeraphorura gen. n. combines characters of different tribes, but three key characters, simple vesicles in postantennal organ, presence of d0 seta on head, and 9 distal setae on tibiotarsi, indicate closer relation to the genera of the tribe Thalassaphorurini. The new genus readily differs from other genera of the tribe by the presence of a rudimental furca in form of a cuticular pocket with 2 + 2 setulae. The taxonomical remarks based on the material from East Siberia and Far East of Russia are given to Dungeraphorura martynovae (Dunger, 1978) comb. n., the second species of the genus.
