Abstract: The Dasypodini are one of the most basal clades of cingulates according to morphologic and molecular phylogenetic analyses. Its living representatives are the group of armadillos with most species and the widest latitudinal geographic distribution, occupying distinct biomes aproximatelly between 40° N and 40° S. In this context, this paper aims to review the diversity of Dasypodini, providing diagnoses and updating the geographic and chronologic distributions of taxa. For that, numerous specimens of cingulates were analyzed and compared. The following species are considered to be valid: Anadasypus hondanus Carlini et al., 1997 (middle Miocene of Colombia); A. aequatorianus Carlini et al., 2014 (late Miocene of Ecuador); Pliodasypus vergelianus Castro et al., 2014 (middle Pliocene of Venezuela); Propraopus sulcatus (Lund, 1842) (Pleistocene?early Holocene ofArgentina, Brazil, Venezuela, Uruguay, Bolivia, and Ecuador); Dasypus bellus (Simpson, 1929) (late Pliocene?late Pleistocene of the United States and Mexico); D. punctatus Lund, 1840 (late Pleistocene?early Holocene of Brazil); and the extant species D. novemcinctus Linnaeus, 1758; D. septemcinctus Linnaeus, 1758; D. hybridus (Desmarest 1804); D. kappleri Krauss, 1862; D. sabanicola Mondolfi, 1967; D. mazzai Yepes, 1933; and Cryptophractus pilosus Fitzinger, 1856, some of them with records since the late Pleistocene. Based on that, we briefly discuss evolutive, biogeographic, and environmental aspects. We corroborate that the extant Dasypodini are more diverse and larger in low latitudes. Lastly, the fossil records show that the group has been historically rectricted to temperate warm tropical and subtropical environments of the American continent.
