ABSTRACT.-We report the first photographic record of the white-nosed coati (Nasua narica) in the southeastern portion of the state of Guanajuato. Although this species is considered abundant and widely distributed in México, Guanajuato is not considered part of its current distribution. Because of the lack of records in surrounding areas, it is not possible to determine if there is an existing linkage to other populations. Thus, it is imperative to continue monitoring this species in the region to identify and assess the connectivity of other established populations and to ensure the species' long-term conservation.
RESUMEN.-Reportamos los primeros registros fotográficos del coatí de nariz blanca (Nasua narica) en la porción Sureste del estado de Guanajuato. A pesar de que ésta especie es considerada abundante y ampliamente distribuida en México, Guanajuato no es considerado como parte de su distribución actual. Debido a la falta de registros en áreas adyacentes no es posible determinar si existe conectividad con otras. Por lo tanto, es necesario continuar con los monitoreos de la especie en la región para poder identificar otras poblaciones establecidas y asegurar la conectividad que permita su conservación a largo plazo.
The procyonid genus Nasua contains 2 species: Nasua nasua and Nasua narica (Wilson and Reeder 2005). The latter, known as the white-nosed coati, is distributed from the southwestern region of the United States into Central America (Gompper 1995). In México, this species has been documented throughout the country except for on the peninsula of Baja California and in the central highlands and is considered common in the coastal slopes along the Pacific Ocean and the Gulf of México (Valenzuela 1998). The species has been associated most frequently with seasonal tropical forests, pine forests, pine-oak forests and scrublands at altitudes ranging from sea level up to 2900 m. There are 2 documented records of the species in northeastern Guanajuato (Sánchez 2014) although compendium studies (Hall 1981, Ceballos and Arroyo-Cabrales 2012) do not recognize the white-nosed coati as part of the fauna of the state. Furthermore, available records of terrestrial mammals from the CONABIO (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad) do not include the white-nosed coati as present in Guanajuato. Espinoza-García et al. (2014) discussed the potential distribution of the species in northeastern México,...
