Ocorrência de Siphonaptera em preá Cavia aperea Exerleben, 1777 (Rodentia: Caviidae) no Rio Grande do Sul, Brasil

Abstract

Due to limited knowledge of Siphonaptera fauna of the Cavia aperea (Brazilian guinea pig) in the State of Rio Grande do Sul, 43 specimens were examined. Six percent of the Brazilian guinea pigs were parasitized with Siphonaptera, which were identified as Polygenis (Neopolygenis) atopus and Polygenis (Polygenis) axius proximus (Rhopalopsyllidae), both with 2.3% of prevalence. P. (Neopolygenis) atopus and P. (Polygenis) axius proximus are reported for the first time on C. aperea in the State of Rio Grande do Sul, Southern Brazil.
