Abstract

A new species of Cavia Pallas, 1766 (mammalia - Caviidae) is described on the basis of 20 skulls and 9 skins from an island of Moleques do Sul Archipelago (Santa Catarina State, southern Brazil), 14 km from the mainland. This species has size and coloration intermediates between C. aperea and C. magna. Cranially, it differs from the other Brazilian species of Cavia by demonstrating a flat sagittal crest, large occipital condyles, broad foramen magnum, shallow labial notch on the second prism of the superior molars, prisms of the mandibular premolar with similar width, first prism of the last mandibular molar wider than the second one and a small lingual notch on the latter prism. Some data on the natural history of this new species are presented. It is possible that this species arose from the isolation of a population of C. magna, 8.000 years ago.
