Hemiphractus proboscideus

Males measure 43–50 mm (1.7–2.0 in) and females 52–67 mm (2.0–2.6 in) in snout–vent length. The head is triangular in dorsal view. Snout is elongated to a proboscis, and there is a large conical and several small tubercles on the eyes. At night, the body is yellowish with brown diagonal or transverse bars and with crossbars in the extremities; the belly is grayish-cream to white. By day, the back is brown with darker brown markings; the ventral surface is brown to reddish brown with orange or yellow spots on the belly, and yellow or white spots on the gular region. Tongue is orange.^[4]

Reproduction seems to occur throughout year as juveniles have been encountered during all months. Development is direct, and the female carries her eggs on her back.^[4]

Hemiphractus proboscideus is a predatory species that eats other frogs. At night, they are typically found sitting on low vegetation.^[1][4] When disturbed, the frog will open its mouth to show its bright-coloured tongue. They can deliver a strong bite.^[4]

Its natural habitats are moist tropical forest at elevations of 100–1,200 m (330–3,940 ft) asl. It is a rare species. No major threats have been identified, but it has declined in Ecuador for unknown reasons. Its range includes several protected areas.^[1]
