A new spiny frog of the genus <i>Pristimantis</i> (Anura, Strabomantidae) from the eastern slopes of the Ecuadorian Andes.

ABSTRACT: A new species of rain frog from the upper montane forest of the eastern Andes in the upper Pastaza watershed, Ecuador is described. Pristimantis fergusoni sp. nov. is characterized by its short snout, conical tubercles on upper eyelids and heels, combined with a scarlet colored belly in females. These unique traits differentiate the new species among other Pristimantis of upper montane eastern Ecuadorian Andes. Phylogenetic analyses support its validity and place it within a clade nested with other tuberculated species occurring along the Andean slopes. Pristimantis fergusoni sp. nov. is currently known from only two close localities (Cerro Candelaria and Chamana Reserves) at elevations between 2972 and 3200 m elevation, within the Llanganates-Sangay Ecol
