Helminth Parasites of Bolivian Monkeys

Parasitologic findings in a survey of 19 Bolivian primates belonging to 9 species of 7 genera, 2 Callicebus moloch, l Aotus azarae, 5 Saimiri sciureus, 2 Cebus albifrons, I C. apella, 1 Alouatta seniculus, 3 Saguinus fuscicolis, 3 S. labiatus and I Cebuella pygmaea, are recorded and discussed. Eighteen of 19 animals harbored one or more species of parasites belonging to more than 20 species. New host records noted in this paper are as follows: Callicebus mooch- Longistriata dubia (Nematoda: Heligmosomatidae), Phaneropsolus sp. (Trematoda: Lecithodendriidae, different from P. orbicularis), Bertiella mucronata (Cestoda: Anoplocephalidae), Porocephalus sp. (Pentastomida); Aotus azarae-Trypanoxyuris interlabiata (Nematoda: Oxyuridae), Phaneropsolus sp.; Cebus apella-Longistriata dubia; Saguinus labiatus- Molineus vexiflarius (Nematoda: Trichostrongylidae), Primasubulura jacchi (Nematoda: Subuluridae), Dipetalonemagracile (Nematoda: Dipetalonernatidae), Phaneropsolus orbicularis, Prosthenorchis elegans (Acanthocephala: Gigantorhynchidae); Cebuella pygmaea- Athesmia foxi (Trematoda: Dicrocoeliidae). The pathogenicity of Molineus torulosus, forming tumours in the small intestinal wall of the host animal, is presented.
