Abstract

The present work aimed to the taxonomic study of nematode parasites of three species of Neotropical primates, donated, already dead, the Federal University of Juiz de Fora, from IBAMA/JF. They are Callithrix penicillata (Geoffroy, 1812), Sapajus apella (Linnaeus, 1758) and Allouatta guariba (Humboldt, 1812). Twenty-six specimens of primates were necropsied, being twenty-two of C. penicillata, two S. apella and two A. guariba. All colected helminths were quantified and treated in accordance with usual helminthological techniques. For the taxonomic study, pictures and drawings were made, for morphometry of the same specimens. Distribution analysis, intensity, density and abundance of parasite communities were made. 10416 nematodes were collected belonging to four different genera, with a significant difference in the number of nematodes in C. penicillata (1391) and S. apella and A. guariba monkey (9025). Primasubulura jacchi were recorded in C. penicillata, Trypanoxyuris (Trypanoxyuris) minutus in A. guariba and S. apella e Parabronema (= Squamanema) bonnei in A. guariba, other than registration of a new species of Onchocercinae, lungs of a specimen A.guariba monkey, named Courduriella sp. The record of T. (T.) minutus in S. apella is the first report of this parasite in this host genus in South America and the collecting Parabronema bonnei was possible to make a redescription of the species that lacks detailed morphological and morphometric characteristics available in the literature.
