Fifty years after: A taxonomic revision of the amphibian species from the Ecuadorian biodiversity hotspot Abra de Zamora, with description of two new Pristimantis species

tubercles described by Lynch); we added descriptions of the characters that are more evident in life. The diagnosis provided herein is based on 48 specimens from the original description (KU 119858–71, 119911–44), one adult female (MUTPL 390), three adult males (MUTPL 112, 294, 389) and two subadults (MUTPL 313, 497) collected from the type locality, and 8 speci- mens collected from the other localities.
