- Emballonurid bats from Colombia: Annotated checklist, distribution, and biogeography Hugo Mantilla-Meluk Héctor E. Ramírez-Chaves Alex M. Jiménez-Ortega Miguel E. Rodríguez-Posada Biología sac sheath wing bats tailed bats Chiropterans Introduction:Genetic data hypothetically place the origin of the most recent common ancestor of thesubfamily Emballonurinae in Africa, suggesting a dispersal event from Africa to South America during theOligocene (30 Ma), and a subsequent allopatric radiation in the New World. Emballonurid genera exist inCentral America where, to date, only one event of diversification has been documented forBalantiopteryxbefore the completion of the Isthmus of Panama land connection in the Pliocene.Methods:Emballonurid bats constitutes an important element of the bat fauna in Colombia. Herein, museumvoucher specimens were used as primary source to generate a checklist of emballonurid bats from Colombia.In addition, selected museum voucher specimens were analyzed to verify their identifications. The checklistis accompanied by references as well as models of potential distribution for each Colombian emballonuridspecies. These distribution maps were used to investigate the affinities, in species composition, amongColombian ecoregions as outlined by Hernández-Camachoet al.(1992), and to determine emballonuridrichness distribution in Colombia and the relationship between environmental variables and patterns ofspecies richness in this group of bats in the country.Results:We report 16 confirmed emballonurid bat species for Colombia and three species potentiallypresent in the country, for a total of 19 species representing the eight recognized Neotropical emballonuridgenera. At 16 known species, Colombia has the second greatest number of Neotropical emballonurid batsafter Brazil (17 spp.).Discussion and conclusion:The checklist presented herein is accompanied by 11 taxonomic anddistributional comments explaining recent changes in taxonomy, species distribution rearrangements, aswell as clarifications and a refinement of the previous records for Colombia. In addition, GeographicInformation System (GIS) models of potential distribution were created for all confirmed species inColombia, and species richness patterns were analyzed. Finally, in a Parsimony Analysis of Endemism wasperformed for Colombian emballonurids we found that diversity within this group of bats in geographicallysubdivided in Colombia into four main regions including: The Biogeographic Chocó; the Magdalena Valley;The Orinoquia; and the Guianan-Amazon region. 2014 artículo científico 2007-3364 https://www.redalyc.org/articulo.oa?id=402333995010 en http://www.redalyc.org/revista.oa?id=4023 Therya application/pdf Asociación Mexicana de Mastozoología Therya (México) Num.1 Vol.5
