Two new nematode species, Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. (Nematoda: Atractidae), from the gastrointestinal tract of Austrochaperina basipalmata (Anura: Microhylidae) collected in Papua New Guinea are described. Orientatractis hamabatrachos sp. nov. is characterized by the presence of the cephalic end armed with 4 wellsclerotized structures, consisting of 2 “horns” extending outward and downward and immediately below a single well-sclerotized spine. It differs from 5 congeners in spicule lengths and caudal papillae arrangements. Rondonia batrachogena sp. nov. is characterized by the presence of a female cloaca. It differs from 2 congeners primarily in body size. Orientatractis hamabatrachos sp. nov. and Rondonia batrachogena sp. nov. represent the first species assigned to either genus found to infect anurans or to occur in the Australo-Papuan region.
