Abstract Bat ectoparasites have a complex natural history narrowly tied to their hosts at ecological, behavioral, and evolutionary scales. As flying and social organisms, bats represent a potential mechanism of dispersal, a source of feeding, and a roost for ectoparasite reproduction. The chiggerflea Hectopsylla pulex (Siphonaptera: Tungidae) is widely distributed across the Neotropics. Females of this ectoparasite have been found in their neosomal form on bats of the family Molossidae, Noctilionidae, Phyllostomidae, and Vespertilionidae. Here we present the record of infestation of chiggerfleas on the Argentine bat, Eptesicus furinalis (Vespertilionidae) in Colombia, representing the first record of the flea on this species, and providing novel genetic information of this poorly known flea species.

The taxonomy of spider monkeys (Ateles spp.) in the Colombian Pacific region has been controversial in the scientific literature, with several hypotheses derived from biogeographical, morphological and genetic analyzes. Uncertainty concerning the specific identity of this taxon makes decision making more difficult for the conservation of this group of primates in the Neotropics. In this study, we present a systematic review which supports that populations of spider monkeys of the north-Andean portion of the Pacific should be assigned to Ateles fusciceps rufiventris.

La taxonomía de los monos araña (Ateles spp.) en el Pacífico ha sido un tema de controversia en la literatura científica, con varias hipótesis derivadas de análisis biogeográficos, morfológicos y genéticos, tendiendo a volver difusa la certidumbre concerniente a la identidad específica de este taxón, lo cual complejiza la toma de decisiones para la conservación de este grupo de primates en el Neotrópico. Por lo tanto, en este estudio presentamos una revisión sistemática que soporta que las poblaciones de mono araña de la porción norandina del Pacífico deberían atribuirse a Ateles fusciceps rufiventris.
