SHORT COMMUNICATION Notes on Ectoparasites of Some Small Mammals from Santa Catarina State, Brazil PEDRO MARCOS LINARDI,1 JOSE RAMIRO BOTELHO,' ALFREDO XIMENEZ,2 CARLOS ROBERTO PADOVANI2 J. Med. Entomol. 28(1): (1991) ABSTRACT small collection of mammals, including 34 individuals from Santa Catarina State, examined for ectoparasites. One species of lick, eight species of mites, species of sucking louse, species of biting louse, and species of flea recorded for the Brst time from Santa Catarina. New host records given for species of Acari, of louse, and of flea. Species that occurred single multiple infestations recorded.
