Abstract

The genus Molossops includes two species that are restricted to South America: Molossops neglectus and Molossops temminckii. The smaller dog-faced dwarf Molossops temminckii is distributed from Colombia to Argentina and has a wide morphological variation and vocal plasticity. In Colombia, this species remains poorly known. To fill distributional gaps, we present novel records from Arauca, Atlántico, Bolívar, Córdoba, and Huila departments. We also present an analysis of the morphometric variation in South America using Principal Component Analyses. These show an external and cranial difference of specimens of Colombia in respect of other and South America populations. In Colombian landscapes dominated by the floodplain savanna of the Orinoco region, Molossops temminckii is smaller than in the other regions of the country, and the previously suggested existence of cryptic diversity within the taxon should be evaluated. Therefore, we suggest further integrative analyses to investigate a possible subspecific status of some Colombian populations.
