Abstract

VANDERHOEVEN, Ezequiel; NOTARNICOLA, Juliana  and  AGOSTINI, Ilaria. First record of Dipetalonema robini Petit, Bain & Roussilhon 1985 (Nematoda: Onchocercidae) parasitizing Sapajus nigritus in northeastern Argentina . Mastozool. neotrop. [online]. 2017, vol.24, n.2, pp.483-488. ISSN 0327-9383.

Species of the genus Dipetalonema are filarial parasites of Neotropical monkeys. Herein, we report the first record of Dipetalonema robini from Argentina and from the black horned capuchin monkey, Sapajus nigritus, providing additionally information on its morphology. Nematodes were found in the abdominal cavity of a male capuchin monkey found in the Parque Nacional Iguazú, Misiones, Argentina. Among Dipetalonema species, the proportion of the different parts of the left spicule (handle and lamina; membranous alae and fila­ment) is a character of taxonomic relevance. The membranous ala is longer than the filament in the single male parasite examined, differing from published data. The differences observed could be due to the small number of specimens measured.

Keywords : Argentina; Atlantic forest; Capuchin monkey; Filarioids; Misiones.
