A new species of Long-eared Brown Bat of the genus Histiotus (Chiroptera) and the revalidation of Histiotus colombiae

The South American bats of the genus Histiotus comprise between four and eight species, but their taxonomy has been controversial and the limits between species and their distribution are not well understood. In Colombia, Histiotus humboldti and H. montanus colombiae have been recorded, but undescribed species has been suggested. We evaluated the species richness and distribution of Colombian Histiotus using morphological, molecular, and acoustic traits. Our results evidence three species in Colombia, the two previously recorded taxa and a new species from the Cordillera Central of Colombia and northern Ecuador that we describe here. We also revalidated H. colombiae as a full species. H. humboldti is widely distributed in the Colombian and Ecuadorean Andes and can be sympatric with the other two species. H. colombiae is restricted to the Colombian Cordillera Oriental. Finally, we highlight the potential hidden diversity within Histiotus in the Peruvian and Bolivian Andes, the need to resolve the evolutionary relationships of the genus, and its implications to the understanding of the processes that have structured the Andean mammal fauna.

Los murciélagos suramericanos del género Histiotus comprenden entre cuatro y ocho especies, pero su taxonomía ha sido controversial y los límites entre sus especies y sus áreas de distribución no son bien entendidos. En Colombia, se han registrado a Histiotus humboldti y a H. montanus colombiae, pero se ha propuesto que hay especies por describir. Evaluamos la riqueza de especies de murciélagos Histiotus colombianos incluyendo caracteres morfológicos, moleculares y acústicos. Nuestros resultados evidencian la presencia de tres especies en Colombia, los dos taxones previamente registrados y una especie nueva de la Cordillera Central de Colombia y el norte de Ecuador que describimos aquí. Además, revalidamos H. colombiae a nivel de especie. H. humboldti presenta la distribución más amplia en los Andes colombianos y ecuatorianos, y puede estar en simpatría con las otras dos especies. H. colombiae es sólo conocida de la Cordillera Oriental de Colombia. Finalmente, resaltamos la diversidad potencial no descrita de Histiotus en los Andes peruanos y bolivianos, la necesidad de resolver las relaciones evolutivas del género y sus implicaciones en el entendimiento de los procesos que han estructurado la fauna Andina de mamíferos.
