There is a distinct yellow or brown line between the eyes, and a dark triangular mark on the back of the head. The ventral surface is whitish to yellowish with tiny golden dots. The throat region is yellowish. The iris is reddish to golden.Similar species: Pristimantis fenestratus has a cream ventral surface, and a gray throat region with dark markings. Pristimantis ockendeni has transverse bars on the hind limbs, a brown dorsum, a throat region with diffuse dark markings, and a ventral surface without tiny golden dots.

Encountered frequently throughout the Reserva Florestal Adolpho Ducke in Brazil.

The species is arboreal and nocturnal. Reproduction occurs in the rainy season (November to May). Males start calling at dusk, from leaves of shrubs or palms about 2 m above the ground; generally in groups of 2-5. Clutches are probably small, with large eggs deposited on the ground, and development to metamorphosis takes place within the egg, as occurs in other members of the genus.
