A New Metastrongyloidean Species (Nematoda) Parasitizing Pulmonary Arteries of Puma (Herpailurus) yagouaroundi (É. Geoffroy, 1803) (Carnivora: Felidae) from Brazil
Angiostrongylus felineus n. sp. (Nematoda, Metastrongyloidea), parasitic in Puma (Herpailurus) yagouaroundi (É. Geoffroy, 1803) (Carnivora, Felidae) from the municipality of Juiz de Fora, Minas Gerais state, Brazil, is described and illustrated herein. Angiostrongylus felineus n. sp. differs from all congeneric species by having the anterior extremity with accentuated cuticular expansion and by smaller size of spicules. This study describes for the first time a species of Angiostrongylus in a wild Felidae in Brazil.Abstract:
