Hyloxalus pulcherrimus is a moderately large species of poison dart frog endemic to Peru.

These stripes are light brown in color near the head and blue-white nearer the vent.

Scientists know this frog from its type locality, 2620 meters above sea level in the Cordillera Occidental.

[1][3] Scientists believe this frog might live in Cutervo National Park but they have not directly observed it there.

Scientists believe this frog may be in some danger of dying out because of habitat loss associated with fires set to prepare the land for agriculture and from the diversion of water for irrigation.
