Resumen El coletrapo norteño (Cabassous centralis) es un armadillo que presenta una baja detectabilidad en campo debido a sus hábitos crípticos, desconociéndose muchos aspectos de su historia natural y distribución.Debido a esto y a la ausencia de exploraciones puntuales, aún permanecen territorios en Colombia sin reportes de la especie.En esta nota se añaden tres registros novedosos de C. centralis para el departamento de Norte de Santander, discutiéndose, a su vez, la identidad taxonómica de un registro previo asignado a esta especie para la región y omitido por la literatura.Con estas evidencias se llena el vacío de información de C. centralis en este sector de Colombia.Se espera un mayor estudio de la especie para el departamento, así como la obtención de más registros biológicos y fotográficos, con el fin de esclarecer asuntos concernientes a los límites geográficos de su distribución y amenazas locales.
El tatú-aí o cabasú grande (Cabassous tatouay) (Cingulata: Chlamyphoridae) es la mayor especie de su género, con una longitud de cabeza-cuerpo de hasta 490 mm y 6,4 kg de masa corporal (Redford & Eisenberg, 1992), aunque se citan ejemplares de dimensiones superiores (Hayssen, 2014;Nigro et al., 2021).Es una de las especies de armadillo menos conocidas por la ciencia, con muy pocos estudios y poco representadas en colecciones científicas (Ubaid et al.,
xenartros más emblemáticos debido a su vinculación con el folklor hondureño (Turcios-Casco et al., 2020).Este armadillo es una de las pocas especies de mamíferos de los cuales hay registros antes de 1900 para Honduras y desafortunadamente ha sido uno de los
The greater naked-tailed armadillo (Cabassous tatouay) is the largest armadillo in the Cabassous genus.It can be distinguished from other species in the genus by its large body size and large ears with granular edges that extend above the top of the head.The presence of C. tatouay in some regions of Brazil and in some Brazilian biomes, such as the Pantanal wetland, was not previously confirmed.This paper presents 12 new records of C. tatouay obtained by camera traps (n = 7), direct observations (n = 1), and roadkills (n = 4) in Mato Grosso do Sul (MS), Brazil.However, two camera trap records were only 14 minutes apart and could potentially represent the same individual.Photographic records are compared with C. squamicaudis to highlight important characteristics that differentiate the species.Finally, these records of C. tatouay extend its range to western Brazil and for the first time into the Pantanal wetland near the transition to the Cerrado savanna.
Dorsal carapace and osteoderm morphological features have traditionally been widely used in both extinct and extant armadillo systematics. However, the intraspecific variability at the carapace level represents a little studied aspect. In this contribution, we analyzed several dorsal carapaces of Priodontes maximus with the purpose of recording such variability. As a result, we describe a total of seven structures concerning the dorsal carapace osteoderm configuration, including distinct terminations of the osteoderm rows, and the most frequent aberrant shapes of the osteoderms. Though the same type of structure can be usually found in several specimens, its frequency and precise location within the carapace are unique to each individual. In this sense, besides improving anatomical descriptions, the identification of these structures can be potentially implemented as a complementary method to help recognize specific individuals being tracked. Moreover, it can represent a very effective recognition method even a long time after death. Given the general decreasing trend of P. maximus populations, it is important to develop as many monitoring tools as possible, in order to support conservation programs for this species.
