Armadillos ( Cingulata )

Living armadillos have traditionally been placed in a single family (e.g., by Wilson and Reeder, 2005; Gardner, 2008), but recent phylogenetic results, including the astonishing discovery that glyptodonts are nested within the radiation of Recent armadillos, suggest that Dasypodidae and Chlamyphoridae be recognized as distinct clades of commensurate rank ( Gibb et al., 2015; Mitchell et al., 2016). Four armadillo species—two dasypodids and two chlamyphorids—all easily distinguished by salient external and cranial characters (table 2; fig. 3), are known to occur in the Yavarí- Ucayali interfluve.

For the purpose of these accounts, we consider armadillos to be adults if the basioccipitalbasisphenoid suture is fused, and if the permanent dentition is fully erupted. In dasypodids (which include the only xenarthrans known to have two functional generations of teeth; Ciancio et al., 2012) some specimens that we consider to be adult by these criteria retain vestiges of the deciduous dentition.
