On Some Filarial Parasites of South American Primates, with a Description of<i>Tetrapetalonema tamarinae</i>n.sp. from the Peruvian Tamarin Marmoset,<i>Tamarinus nigricollis</i>(Spix, 1823)

Abstract

1. The results of a survey of 194 Peruvian and Colombian primates for filarial infections are presented. Nine genera and 14 species of marmosets and monkeys are represented in the survey. A blood film survey revealed microfilariae in 82, of 42% of the animals. Adult worms were recovered from 21 of 61 dissected animals. The 209 adult worms belong to four species: Dipetalonema gracile, Dipetalonema caudispina, Tetrapetalonema marmosetae , and Tetrapetalonema tamarinae , a new species. 2. New host records for Dipetalonema gracile are: Tamarinus nigricollis, Cebus albifrons , and Saimiri boliviensis. Saimiri boliviensis is a new host for Dipetalonema caudispina . New hosts for Tetrapetalonema marmosetae are: Oedipomidas oedipus, Saimiri sciurea, S. boliviensis , and Ateles paniscus . 3. The adult worms and microfilaria of a new species of filarial worm, Teirapetalonema tamarinae , are described from a Peruvian tamarin marmoset, Tamarinus nigricollis .
