A new species of the Hyloscirtus larinopygion group from Nudo de los Pastos, Nariño department, Colombia is described. Hyloscirtus tigrinus sp. nov. can be distinguished easily from similar species by the presence of a fleshy and prominent calcar tubercle and by its distinctive color pattern. Some remarks on throat and ventral coloration in Hyloscirtus caucanus, H. larinopygion, H. lindae and H. tigrinus are presented. The throat coloration is highly variable and cannot be used to diagnose any of these species.
