In this paper 19 additional mammalian species are reported in the Atlantic forest of the Paranean Serra do Mar, southern Brazil, including threatened and rare species. These findings resulted from a one-year field research in the western slope of the Serra do Mar, Piraquara municipality, with additional review of reports about mammal distribution in the region. Preliminarily mammal richness in the region is round 54 species, but this number could be higher with more systematic surveys, particularly with regards to bats. The occurrence of the hog-nosed skunk, Conepatus chinga (Molina, 1782), is reported for the first time in the eastern portion of Paraná, a State vastly deforested during the last century in Brazil.
