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 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.

The species was described on April 20, 2018, in the scientific journal ZooKeys by researchers Juan C. Sánchez-Nivicela, Elvis Celi-Piedra, Valentina Posse-Sarmiento, Verónica L. Urgilés, Mario Yánez-Muñoz, and Diego F.

[2] Its specific epithet derives from the Greek word ἐρυθρός (erythros), meaning red, an allusion to the color of its skin, which allows it to be distinguished from other species.

[2] The park where it is endemic seems to be well preserved, but due to human pressure, the change of vegetation cover, anthropological use of the land and the lack of protection in the surrounding regions, the species is suffering the loss of its habitat, which currently corresponds to an area smaller than one square kilometer.

[2] Like all species of its genus, it has direct development, with no aquatic larval stage, and with the eggs being laid on the forest floor, and can live without needing bodies of water.
