Resumen:
The Quimbaya toad, Atelopus quimbaya, is a small bufonid endemic to the Central Andes in Colombia and it is categorized as Critically Endangered by the International Union for Conservation of Nature-IUCN-. Here, we report historical sightings and recent extensive surveys conducted by us in three historical localities where the Quimbaya toad was reported. The last observations of the Quimbaya toad were between 1994 and 1997 in these three localities. Although we conducted three extensive surveys during several years (2003–2004, 2010–2011, and 2011–2012), we could not detect any individual, nor eggs or tadpoles. We discuss some potential drivers of population declines and suggest that this species be declared as Possibly Extinct. However, we believe that additional surveys should be conducted with the aim to find new populations in other nearby localities and also to test for the presence and prevalence of chytrid fungus in the region. Finally, we do not have sufficient evidence to firmly establish which factors drove the decline of this species. © 2018, Sociedad Herpetologica Mexicana. All rights reserved.
