5 SPECIES (3 NEW) OF TRICHOSTRONGYLOID NEMATODES COPARASITES OF DASYPROCTA-AZARAE, FROM PARAGUAY

In the guts of three Dasyprocta azarae from Paraguay, five coparasite species of Pudicinae were found: (1) Pudica pudica (Travassos, 1921). (2) Pudica gonosoma n. sp., characterized by its synlophe with a low number of dorsal crests and a decreasing gradient in size from right to left on the median sides; in males, the beginning of the externo-dorsal rays are at mid-length of the dorsal ray; in females, the posterior part of the body is twisted. (3) Durettestrongylus baudi n. sp. is separated from the type species (and only species in the genus) by the synlophe: the left crest is about the same size along the entire body length and the other crests disappear more posteriorly than in the type species; in males, the dorsal ray has a common trunk with the externodorsal rays and is divided at the third distal section. (4) Fuellebornema granulosa Durette-Desset, 1970. (5) Fuellebornema demarsae n. sp. closely related to F. nevai n. sp. (= F. agoutii sensu Travassos, 1937, nec Neiva, Cunha et Travassos, 1915) is differentiated by the caudal bursa pattern. The genus Fuellebornema Travassos et Darriba, 1929, was synonymized by DURETTE-DESSET, 1971 with Heligmostrongylus Travassos, 1917, and is herein revived. It is the only genus among the Pudicinae to have a bursal caudal type 1-3-1. A list of Fuellebornema species is also given.
