Three species of the oligochaete genus Pristina (Naididae, Clitellata), one of them new to science, are described from soil and litter samples originating from terra firme sites of the primary rain forest at the Brazilian Agroforestry Research Facility in Central Amazonia: P. marcusi sp. nov., P. jenkinae (Stephenson, 1931) and P. notopora Cernosvitov, 1937. Investigations were carried out on live and preserved material, with emphasis on non-chaetal. non-sexual characters of the live anatomy, usually neglected in recent Naididae taxonomy. P. marcusi sp. nov. is characterized by simple-pointed and bayonet-shaped needle chaetae and by a regular pattern of ellipsoid intrastomachal cavities. P. notopora is redescribed in full detail for the first time since its original description, including the exceptional dorsal opening of the nephridia.
