The northern naked-tailed armadillo (Cabassous centralis) is a small, poorly known armadillo species. We update the state of knowledge on this species, provide information on its current and potential distribution, and assess its conservation status and threats. We reviewed the existing literature and obtained georeferenced records from publications, online databases, and field researchers. A total of 174 documents mentioning C. centralis have been published between 1855 and 2019, about half of which (83) provided information on its distribution. The majority of publications came from Colombia. About 10% of publications included information about its ecology, concluding that it is a rare species that mainly occurs in areas with secondary vegetation. It seems to prefer complex habitats, as it is rarely found in fragmented or modified habitats. Consequently, it is possible that its ability to adapt to land use change is low. A total of 224 confirmed records allowed us to extend the species range to the northern Lacandona Forest in Mexico, the Andes of Colombia and southwards in Ecuador. Nevertheless, a distribution model suggests that the species could be even more widely distributed. C. centralis is listed in a threatened category in two countries, whereas more than half of the range countries have not assessed its conservation status. We consider its current global listing as Data Deficient to be appropriate, as many aspects of its ecology, reproduction, population size and trend, and the degree of impact of potential threats remain unknown.
