On the Papuan Elocobdella novabritanniae, the Oceanian Abessebdella palmyrae (Haemadipsoidea: Domanibdellidae), and an Oceanian barbronid (Hirudinea)
Generic definitions and detailed descriptions are given for the two domanibdelline land-leeches. An analysis of the nature of the barbronids indicates: separation of these from the Erpobdellidae s.l.; division into Australian and Oriental groups; and association of the Oceanian barbronid with the group of the Australian Region. It is noted that the characteristic strepsilaematous pharynx is formed by transposition of the ridges, not by torsion.
