C. ABSTRACT: As a result of a systematic review of nectar feeding bats in the genus Lonchophylla (Phyllostomidae) deposited in the scientific collections of the Instituto de Ciencias Naturales (ICN) in Bogotá and the Museo de Historia Natural of the Universidad del Cauca (MHNUC) in Popayán, we report range extensions for three Colombian species. Lonchophylla cadenai is reported from Pueblo Rico, Risaralda, representing an increase in both altitudinal and latitudinal ranges; L. handleyi is reported from Cueva de los Guácharos, Huila, confirming the presence of this taxon in Colombia and representing its northernmost known record; and L. pattoni is reported from Leticia, Amazonas, which constitutes the third known collecting locality for this taxon and represents the northernmost known record for the species. In addition, an annotated list of all Lonchophylla specimens present in the two studied collections is included. RESUMEN: Extensiones en los rangos de distribución y notas taxonómicas sobre murciélagos del género Lonchophylla (Phyllostomidae) de Colombia. Como resultado de una revisión sistemática de murciélagos nectarívoros del género Lonchophylla (Phyllostomidae) depositados en las colecciones científicas del Instituto de Ciencias Natu- rales (ICN) en Bogotá y el Museo de Historia Natural de la Universidad del Cauca (MHNUC) en Popayán, reportamos extensiones en los rangos de distribución para tres especies. Lonchophylla cadenai es registrada de Pueblo Rico, Risaralda, y representa un incremento tanto en su rango altitudinal como latitudinal; L. handleyi es registrada para la Cueva de los Guácharos, Huila, lo cual confirma la presencia de este taxón en Colombia, siendo esta la localidad más al norte conocida para esta especie; y L. pattoni es registrada para Leticia, Amazonas, la cual constituye el tercer registro conocido para esta especie y el registro más norte de su distribución. Adicionalmente, se incluye una lista anotada de los ejemplares del género Lonchophylla revisados en estas dos colecciones. Key words: Bats. Distribution. Lonchophyllinae. Neotropics.
