A new species of a free-living marine nematode found in Brazil is described: Trileptium ribeirensis sp. nov. The type material is deposited in the Nematoda collection of the Museu de História Natural da Bahia, located at the Universidade Federal da Bahia. Trileptium includes eleven valid species of nematodes that have teeth and jaws positioned forward. The species was collected with the help of corers (3.5 cm in diameter and 30 cm long) on a sandy beach in Bahia. This species is distinguished from its congeners based on a combination of characters of the male (cuticle, buccal cavity, supplement and gubernaculum). An updated taxonomic key to the genus is presented.(AU)
