| Spanish abstract | Se reporta el cariotipo de un ejemplar hembra C. brevicauda capturado en el municipio de Chachagüi, Colombia. El cariotipo fue obtenido a partir de médula ósea con tinción convencional de Giemsa. Con este reporte se incrementó a dos el número de reportes citogenéticos de C. brevicauda para poblaciones de Colombia. El cariotipo de C. brevicauda analizado presentó 2n = 20 y NF = 36, mientras que la fórmula cromosómica del ejemplar esta compuesta por un par sexual, dos pares subtelocéntricos, dos pares submetacéntricos y cinco pares metacéntricos. Se determinaron variaciones en la morfología de los cromosomas, pero uniformidad en el número cromosómico. La información disponible indica la necesidad de estudios para describir los cariotipos de C. manu y C. monohernandezi |
| English abstract | Introduction: The only record of a Carollia brevicauda (Schinz, 1821) karyotype in Colombia to date was described from a single specimen collected from Leticia (department of Amazonas, Colombia). In this study, we offer a description of the karyotype of a female specimen of C. brevicauda, collected at 1,647 m in the locality of Chachagüi, in the Colombian Andes. Methodology: The karyotype was obtained from bone marrow and conventional staining with Giemsa. We describe the chromosomal number, fundamental number and the karyotypic pattern. We compared the karyotype with others proposed for the species and several closely related species. Results: This study increased the number of karyotypes reported for Colombian populations of C. brevicauda. The karyotype of C. brevicauda described in this paper agrees with karyotypes of other populations with 2n = 20 and FN = 36. The karyotypic pattern includes one sexual pair, two subtelocentrics pairs, two submetacentrics pairs and five metacentrics pairs. Discussion: The pattern recorded herein is different to other reported for the species and the genus. The descriptions of variations in chromosomal morphology in C. brevicauda are incomplete, but it is possible that the different karyotypic patterns are indicators of polymorphism within the genus. Other studies are necessary to describe the yet undescribed karyotypes of C. manu and C. monohernandezi and to obtain additional evidence for the phylogenetic reconstructions of Carollia |
