Centrolenidae have been reported from Colombia, including two species of to the genus Cochranella that inhabit the Chocoan lowlands: Cochranella euknemos and C. litoralis (Frost, 2014). Ortega-Andrade et al. (2013) suggested the presence of Cochranella mache on the Chocoan lowlands of southwestern Colombia, based on ecological niche models; however, all known records of C. mache came from the north-western lowlands of Ecuador (Guayasamin and Bonaccorso, 2004; CisnerosHeredia et al., 2007, 2008, 2009; Ortega-Andrade et al., 2013). Herein we report the first records of C. mache from Colombia, base don recent fieldwork and revision of amphibian collections deposited at Universidad del Valle (UV-C) and Instituto de Ciencia Naturales, Universidad Nacional de Colombia (ICN). These records significantly increase the geographic range of the species, and call for a review of the range of C. euknemos in the country One adult male Cochranella mache (photographed and released, Figure 1.A) was observed at Vereda El Salto (3.855317 N, -76.78125 W, 750 m, Figure 2), Corregimiento 18, municipality of Buenavantura, department of Valle del Cauca, on 25 March 2014. It was active at 16h40 on leaf litter in primary forest next to a ravine, after rain. An adult male (UV-C 13658) was collected at Guaimia (3.718611 N, -76.963056 Herpetology Notes, volume 8: 161-163 (2015) (published online on 10 April 2015)
