Description
Summary:A new species of the Andean genus Osornophryne is described from the cloud forests of Volcán Sumaco in central Ecuador. This species can be distinguished from all other members of the genus by the combination of its unique ventral coloration, rugose skin, and pustular dorsal ridges. Individuals of two other species of Osornophryne, O. guacamayo and O. antisana, were encountered at the same locality. I discuss some aspects of the microhabitat preferences and diets of these toads. Morphometric comparisons and notes on the status of digital reduction in the genus are included. /// Se describe una nueva especie del género andino Osornophryne de los bosques nublados del Volcán Sumaco en Ecuador central. Esta especie puede distinguirse de otras del género por el combinación de su coloración ventral, piel arrugada y cordoncillos dorsales y pustulados. Individuos de dos otras especies de Osornophryne, O. guacamayo y O. antisana, fueron en la misma localidad. Se discute unos de los aspectos de la ecología de estos sapos. Incluyo unas comparaciones morfometricas y notas respecto a la condición de reducción digital en este grupo.
