New Family, New Genus, New Species of Acanthocephala (Echinorhynchida) from the Lizard, Sphenomorphus granulatus (Sauria: Scincidae), from Papua New Guinea

Sauracanthorhynchus sphenomorphicola n. gen., n. sp. from the intestines of the skink Sphenomorphus granulatus (Scincidae) from Papua New Guinea is described and illustrated. Sauracanthorhynchus sphenomorphicola is characterized by a subterminal, spheroid proboscis supporting 25 hooks arranged in 10 alternating longitudinal rows of 2 and 3; apical hooks slightly shorter than medial and posterior hooks. The trunk is commaform with an anterior expansion; 2 contiguous ovoid testes are located in the anterior third of the trunk. Sauracanthorhynchus sphenomorphicola is sufficiently different from other species assigned to the Echinorhynchida that a new family, Sauracanthorhynchidae is erected for it.
