Resumo: ABSTRACT Given the difficulty of collecting biological samples from rare and elusive species, the collection and analysis of hair is a good alternative for the identification and differentiation of mammal species. Our study aimed to test the reliability of the morphological identification of guard hairs from cervids that inhabit Brazil. We collected guard hairs from five body regions (head, neck, side of the thorax, back, and buttocks) of one male and one female of eight Brazilian cervid species, and we analyzed hair cuticular and medullar patterns. We carried out qualitative and quantitative analyses on the morphology of the medullar (total thickness and thickness of the medulla) and cuticular patterns (area and perimeter of the scales) of the guard hairs. Based on the obtained data, we found no notable morphological differences in the cuticular and medullar patterns in the guard hairs. Furthermore, our quantitative analysis demonstrated that the guard hairs are not a useful material for differentiating the Brazilian deer species.
