A New Species of Pristimantis (Amphibia: Strabomantidae) from the Cloud Forest of Sangay National Park, Ecuador

Abstract:

We describe Pristimantis tinguichaca sp. nov., a member of the Pristimantis unistrigatus species group, from the cloud forests of Sangay National Park located on the eastern slopes of the Andes in southeastern Ecuador. The new species was collected in cloud forests and cattle pastures at 2,750-2,830 m elevation. It differs from other members of the P. unistrigatus group by the presence of small conical tubercles on the upper eyelids and heels, as well as by its reddish-colored iris. It is further distinguished by its small conical ulnar and tarsal tubercles. A single sharp metallic note composed of a modulated frequency characterizes the call. Stomach content analysis revealed a diet composed principally of beetles (51.7%).
