title: A new species of Pterygodermatites (Nematoda: Rictulariidae) from the Incan shrew opossum, Lestoros inca.
abstract: Pterygodermatites ( Paucipectines ) hymanae n. sp. (Rictulariidae) collected from the Incan shrew opossum, Lestoros inca , from Peru is described herein. These nematodes show a subapical, slightly dorsal oral opening and a laterally compressed buccal capsule with 2 conspicuous lateral walls and a dorsal wall. Each lateroventral wall possesses 4 relatively large denticles, and the dorsal wall has 6 denticles. Females are characterized by a conspicuously large postvulvar 37th spine, which may reach 1 mm. This is the first record of endoparasites in the Incan shrew opossum and the fifth species of Pterygodermatites recorded in New World marsupials.
