Resumo

Characters of the four species of large Artibeus (Chiroptera, Phyllostomidae) occurring in Paraiba and Pernambuco States, Brazil. The purpose of this study was to reevaluate the diagnostic characters of the four species of the subgenus Artibeus, A. fimbriatus, A. lituratus, A. obscurus, and A. planirostris, that occurs in Paraiba and Pernambuco States, Brazil, describing the inter-specific variation in the material available in the collections of the Universidade Federal da Paraiba and Universidade Federal de Pernambuco. A total of 254 specimens were examined, 12 of A. fimbriatus, 41 of A. lituratus, 35 of A. obscurus and 166 of A. planirostris. For each species, descriptions of external characters and skull are supplied as well as eight cranial measurements that express the differences among the species observed with naked eye. With the discriminant canonical analysis, the four species can be distinguished. Mahalanobis distances showed a larger similarity between A. planirostris and A. obscurus as well as between A. fimbriatus and A. lituratus. The largest distance was observed between the last two species and A. obscurus. We conclude that in Paraiba and Pernambuco occurred four species of the subgenus Artibeus that may be distinguished morphologically as well as through multivariate analyses.
