First confirmed records of the rare Short-eared Bat, Cyttarops alecto Thomas, 1913 (Chiroptera: Emballonuridae), from the Orinoco Llanos of Colombia

Abstract

We confirm the occurrence of the rare bat Cyttarops alecto in piedmont and alluvial plain savannas of the Orinoco Llanos. Our records are the first for the species in Colombia in 22 years. The species was known only from Neotropical rainforests and one locality in the Cerrado formation in Brazil. Our records are supported with voucher specimens that match the diagnosis and variability described for the species. With these records, we reduce the geographical distribution gap between known Trans-Andean and Cis-Andean localities of this species in the northern Neotropics.

Mamíferos de la cuenca del río Cravo Sur: estado de conocimiento y conservación

“…En la actualidad, se ha evidenciado un creciente interés en generar conocimiento científico acerca de la ecología y diversidad de las especies de mamíferos, asociados a los ecosistemas de la Orinoquía colombiana, reflejada en diferentes publicaciones en los departamentos que la conforman.

Northern distributional extensions of Peropteryx leucoptera and Peropteryx pallidoptera (Chiroptera: Emballonuridae) from Vichada, Colombia

“…The bat fauna of the Colombian Llanos has been considered little diverse (Rodríguez-Mahecha et al 2005;Mantilla-Meluk et al 2009;, but recent studies on bat assemblages (Estrada-Villegas & Ramírez 2013;Morales-Martínez et al 2018) and new records of bat species in the region (Calderón-Capote et al 2016;Rodríguez-Posada et al 2017), draw attention to a potential higher diversity, underestimated by the low number of studies in the region. The knowledge about mammals in the Orinoco Llanos is low due to the sampling is small and disperse geographically and temporally with spread inventories in specific localities (Ferrer-Pérez et al 2009;Trujillo et al 2010).…”
