Pristimantis minimus is a minute frog from the family Craugastoridae. It is found in the Cordillera del Cóndor at elevations between asl on either side of the valley of the Rio Nangaritza, in the Zamora-Chinchipe Province of Ecuador. The species is the smallest known frog found in Ecuador to date, and is the smallest of the genus Pristimantis. It is suggested that this miniaturization is an adaptation to resource-poor environments.
