Abstract
We document the first record of Laval’s Disk-winged Bat, Thyroptera lavali Pine, 1993, from the Amazon region of Colombia. This record increases to four the number of Thyroptera species in the country and extends the known range of T. lavali 428 km east and 338 km north from the nearest previous localities. The distribution of this species now comprises 11 localities from six ecoregions and five countries: Brazil, Colombia, Ecuador, Peru, and Venezuela. We highlight the paucity of knowledge on bat species in the Colombian Amazon.
Highlights
The Neotropical bats of the genus Thyroptera Spix, 1823 are commonly known as disk-winged bats owing to the presence of suction disks located at the wrists and ankles which enable these bats to adhere to foliage (Wilson 2008; Velazco et al 2014; García et al 2019)
T. lavali has not been recorded in Colombia, the distributional gap among Venezuelan and the western Amazonian localities in Ecuador and Peru (Lee 2019) suggests the presence of this species in the Colombian Amazon

Summary
The Neotropical bats of the genus Thyroptera Spix, 1823 are commonly known as disk-winged bats owing to the presence of suction disks located at the wrists and ankles which enable these bats to adhere to foliage (Wilson 2008; Velazco et al 2014; García et al 2019). In Colombia, three species have been recorded: T. tricolor, T. discifera, and T. devivoi (Rodríguez-Posada et al 2017). Thyroptera lavali is an uncommon species, known by few specimens collected from few localities in northeastern Venezuela, eastern Ecuador, and the Amazon basin of Brazil and Peru (Lee 2019). T. lavali has not been recorded in Colombia, the distributional gap among Venezuelan and the western Amazonian localities in Ecuador and Peru (Lee 2019) suggests the presence of this species in the Colombian Amazon. We present the first confirmed record of T. lavali in Colombia based on morphological and molecular data
