Adult: Species description based on Savage (2002). A medium-sized treefrog (males to 39 mm, females to 45 mm). Dorsal: Dorsal coloration may be purple, brown, or green. Green individuals sometimes have black spots. The skin of the dorsum is smooth. Ventral: The ventral surface is yellow, often heavily pigmented with black or even mostly black. Concealed surfaces: The rear surfaces of the thighs are covered in white or yellow spots against a dark brown background. This coloration and patterning is usually also present in the groin and on the inner surfaces of the thighs. Eye: The iris is green, brown, or coppery. Breeding season: Breeding occurs both in the dry season as well as during the early part of the wet season (Savage 2002). Males call from the margins of streams or from rocks in streams (Savage 2002). Reproduction has not been observed (Savage 2002). Egg: Gravid females contain 100-149 eggs (Lang 1995). Tadpole: The tadpole body is oval-shaped, wth a short tail and relatively low tail fins (Savage 2002). A very large oral disc surrounds the mouth, which tadpoles use to cling to rocks in swift-moving streams (Savage 2002). Tadpoles are mostly black with some gold flecking (Savage 2002). Habitat: Montane forest between 1930-2800 m. Ecology: Isthmohyla pictipes is usually found in association with streams (Savage 2002). They hide under rocks along stream margins during the day (Savage 2002). Call: A low "eeck", sometimes repeated twice in a row (Savage 1969, Duellman 1970) Type locality: Cerro Utyum, 5000-7000 ft, Cantón de Talamanca, Provincia de Limón; 1524-2134 m (Costa Rica) |
