AB  - Thoracostomopsidae are common predatory marine nematodes found in
   littoral and sub-littoral sands. The buccal cavity is characterised by
   a mandibular complex and onchia (teeth) forming grasping jaws. Three
   constituent subfamilies and genera are distinguished by variations in
   the development of these structures. Of the three subfamilies,
   Thoracostominae have been found in sub-littoral habitats and have not
   been reported from Australia. A number of species from several genera
   of Enoplolaiminae have previously been recorded from southeastern
   Australian beaches. In this paper, Trileptium australis n. sp.
   belonging to the third subfamily, Trileptiinae, is described from one
   of these beaches. In this genus, weakly developed mandibles and one, or
   three, well developed onchia are situated closer to the mouth opening
   than in Enoplolaiminae, and the lips have a lower profile. Important
   specific diagnostic characters of Trileptium australis n. sp. are the
   possession of three onchia, absence of cuticular annulation, presence
   of a precloacal supplementary organ, thin strongly curved spicules with
   mid-ventral pegs and a gubernaculum that loops over the spicules. A
   dichotomous key for the 11 described species, based on male characters,
   is provided. The geographical distribution of all the described species
   is reviewed. One species, T. subterraneum has a very wide geographical
   distribution, but other species appear to be restricted to one sea or
   ocean.
