A new species of Pristimantis (Anura, Craugastoridae) from the Cajas Massif, southern Ecuador

Resumen

A new species of <i>Pristimantis</i> is described from the highland paramos on the eastern slopes of the Cajas Massif, southern Andes of Ecuador, at 3400 m. This new species is characterized by having a distinctive reddish color, cutaneous macroglands in suprascapular region and surfaces of arm and legs, and by lacking dentigerous processes of vomers. The cutaneous macroglands are similar to those exhibited by several species of the <i>Pristimantis orcesi</i> group, and may suggest a close phylogenetic relationship. The new species could be a latitudinal substitution of <i>Pristimantis orcesi</i> in the southern Andes of Ecuador.
