| description | <p>We describe a new species of Andean toad, <em>Osornophryne angel</em> sp. nov., based on specimens collected at Páramo del Angel, province of Carchi, Republic of Ecuador. This new species is a medium-sized toad diagnosed from other species of <em>Osornophryne</em> by having granular skin with glandular ridges and tubercles and by the presence of a projected papilla or a proboscis at the tip of the snout. <em>Osornophryne angel</em> sp. nov. exhibits strong sexual dimorphism, females are larger and have a projected papilla instead of the male’s extended proboscis at the tip of the snout. Considerations on the sexual dimorphism are important to evaluate intra and inter-specific variation in <em>Osornophryne</em>, and lack of its understanding has resulted in identification errors. We revised the taxonomic status of some Colombian populations recently reported in the literature, and found that specimens reported as <em>O. bufoniformis</em> in fact correspond to four different species, including a putatively undescribed species. Colombian specimens reported as <em>O. antisana</em> and <em>O. guacamayo</em> correspond to apparently undescribe taxa, thus the records of both species for Colombia are invalid.</p> |
