Pristimantis erythros is a species of amphibian in the family Craugastoridae, and can be found in Cajas National Park in Chiquintad parish, Ecuador.
Its striking characteristics are its scarlet red coloration, which differentiates it from all the species of the genus Pristimantis, and the presence of parotid glands on the trapezius and suprascapular muscles. It has an average length of 38 to 42 millimeters in females and 37 millimeters in males. It has direct development, as do all the species of its genus, and does not have an aquatic larval stage.
It was described on April 20, 2018, in the scientific journal ZooKeys by a group of six researchers. Its specific epithet derives from the Greek word ἐρυθρός (erythros), meaning red, an allusion to its unique coloration. It has not yet been catalogued by the International Union for Conservation of Nature, but because it is losing habitat and occupies an area smaller than one square kilometer, researchers classify it as a critically endangered species.
