Adult: Species description based on Savage (2002). A medium-sized treefrog with a very long snout (males to 49 mm, females to 53 mm). Dorsal: The dorsal surface is greyish brown or drab green and covered in small tubercles. The upper surfaces of the arms and legs are barred. Ventral: The ventral surface is pale cream. Concealed surfaces: The front and rear surfaces of the thighs are yellowish or orange barred with black. The groin is more yellow or green, with some small black spots. Eye: The iris is golden or more bronzy. Extremities: The hands and feet are moderately webbed.
Breeding season: Breeding occurs throughout the rainy season, but activity is highest just after the rains begin (Savage 2002). Males usually call from the ground (Savage 2002). Males will remain calling at breeding ponds night after night for long periods of time (Bevier 1997). Egg: Clutches of up to 700 eggs are laid in ponds (Savage 2002). Embryos hatch after approximately 36 hours (Savage 2002). Tadpole: The tadpole has a small head and a short tail with very large tail fins (Savage 2002). The dorsal fin extends onto the rear half of the body (Savage 2002). The body is light yellow-grey, lightening further to a cream color on the tail (Savage 2002). The tail is transparent except for some large dark spots (Savage 2002). Tadpoles metamorphose in 40-88 days (Jungfer 1987). Tadpoles are carnivorous, consuming small crustaceans and aquatic arthropods, as well as eggs of con-and hetero-specific frogs (Jungfer 1987, Savage 2002).
Habitat: Lowland and premontane forest to 700 m. Ecology: An inhabitant of both forest and more open grassy areas (Scott 1983). Con- and hetero-specific tadpoles are a significant source of larval mortality in this species (Roberts 1994). Call: A low-pitched "wraak" (Duellman 1970, Savage 2002) Type locality: Nicaragua
