Abstract Oigolaimella kruegeri n. sp. and Oigolaimella ninae n. sp. are described. Oigolaimella kruegeri n. sp. males can be recognised by the lack of the gubernacular keel characteristic of other Oigolaimella species and by the modified distribution pattern of the genital sensillae. Oigolaimella ninae n. sp. can be recognised and distinguished from the other members of the genus by the refractive cuticularised ring formed by the anterior edge of the cheilostomatal collar. Oigolaimella longicauda (Claus, 1862) n. comb. is accepted as a valid species, regarded as a senior synonym of O. agilis (Skwarra, 1921) and redescribed. Oigolaimella diplogaster (von Linstow, 1890) n. comb. is proposed. The phylogenetic relationship of Oigolaimella is discussed and an ecological characterisation of the taxon given on the basis of observations on feeding behaviour and locomotion in the habitat.
