About Pristimantis altamazonicus (Barbour & Dunn, 1921)
Description: In snout–vent length, adult males of Pristimantis altamazonicus measure 17–20 mm (0.67–0.79 in), while adult females measure 28–30 mm (1.1–1.2 in). The snout is moderately short and sub-acuminate. The dorsal skin is smooth, but adult males have small, scattered tubercles. Neither fingers nor toes are webbed, but both have lateral fringes. The dorsum and flanks are brown with reddish and black stains. A distinct W-shaped mark is present in the scapular region. Longitudinal cream stripes and dark blotches may also occur. Habitat and conservation: Pristimantis altamazonicus lives in closed-canopy primary tropical forests, and is occasionally found in flooded or secondary forests. While individuals may be found in leaf litter during the day, they are more typically found perched on low vegetation in the forest at night, where they call. This species occurs at an altitudinal range of 74–1,462 m (243–4,797 ft) above sea level. Although habitat loss can be a threat to local populations, the species Pristimantis altamazonicus as a whole does not face major threats.
