Description

Adult males measure 15–19 mm (0.6–0.7 in) and adult females 24–29 mm (0.9–1.1 in) in snout–vent length. The snout is long, subacuminate in dorsal view, and rounded in lateral profile. The tympanum is round and prominent. The fingers and the toes have lateral fringes and round terminal discs but no webbing. Dorsal skin has many non-conical tubercles. The dorsum is copper brown. There are irregular spots that are cream, nearly black, or orange. The flanks are dark brown with paler slanting stripes. The posterior/hidden surfaces of the thighs are dark brown with orange spot. The venter is almost white to pinkish. Grey marbling may be present on the throat. The iris is pale copper to reddish-copper, with thick black reticulation.[3]

Habitat and conservation

Pristimantis viejas occurs in sub-Andean forests at elevations of 565–1,880 m (1,854–6,168 ft) above sea level.[1][4] Individuals can be found under bushes, in forest edge, secondary forest, and in open areas in forests. It is nocturnal. Breeding occurs through direct development (i.e., there is no free-living larval stage).[1]

Pristimantis viejas is a common and adaptable species that seems to benefit from a degree of disturbance to forest habitats. It is not facing any significant threats.[1]
