title: Cruorifilaria tuberocauda gen. et sp. n. (Nematoda: Filarioidea) from the capybara, Hydrochoerus hydrochaeris in colombia.
abstract: Cruorifilaria tuberocauda gen. et sp. n. is described from blood vessels of the kidney, heart, and lungs of the capybara, Hyrochoerus hydrochaeris, in Colombia, S.A. The adult worms are robust, of moderate size (females approximately 42 mm long, males about 27 mm long), and tapered at both ends. The males have unequal, dissimilar spicules, lack a gubernaculum and possess both pre- and postanal papillae. The unsheathed microfilaria is found in the peripheral blood. Even though a severe tissue response is seen in the walls of the blood vessels occupied by the adult worms, it appears to be a common parasite in the population of capybaras surveyed.
