abstract
Eudorylaimus nudicaudatus sp.n. is described from western Dronning Maud land, Antarctica. The new species is characterised by an exceptionally small stylet aperture and by the fact that the outer layer of the cuticle does not embrace the tail terminus. E. nudicaudatus sp.n. is compared with other Eudorylaimus spp. described from Antarctic regions, viz E. antarcticus (Steiner 1916) and six species described by Loof (1975): E. verrucosus, E. isokaryon, E. spaulli, E. coniceps, E. pseudocarteri and E. paradoxus.
