Pristimantis mallii

Adult males measure 12–21 mm (0.5–0.8 in) and adult females 23–43 mm (0.9–1.7 in) in snout–vent length. The snout is broadly rounded in dorsal view. The tympanum is visible, albeit slightly covered by the supratympanic fold. The fingers have narrow lateral fringes and terminal discs. The toes have slightly defined lateral fringes and terminal discs; no webbing is present. The upper eyelids bear 1–2 subconical tubercles and some rounded tubercles. Skin on the dorsum and flanks is shagreen. Scapular folds are distinctive. The dorsum and flanks light are brown to brown. There are irregular dark brown marks bounded by dirty or greenish cream or light brown. The groin has irregular yellowish marks. The venter is light gray or cream, spotted with brown. The iris is golden coppery with black reticulations and a reddish horizontal stripe.[1][3]

Pristimantis mallii is known from the montane cloud forests of the east-central slope of the Andes at elevations of 1,300–2,190 m (4,270–7,190 ft) above sea level. All specimens were found in herbaceous and shrub vegetation inside mature forest some 1.5–4 m (4 ft 11 in–13 ft 1 in) above the ground.[1][3]

The Río Zuñag Reserve is located in the buffer zone of the Llanganates National Park.[1]
