Adult: Species description based on Savage (2002). A medium-sized frog with a pointed snout (males to 52 mm, females to 63 mm). In males, the undersurfaces are mottled with grey or black. Dorsal: Dorsal coloration consists of large or small green patches on a golden brown background. The coloration darkens to brown along the sides, and this coloration extends forward onto the face in the form of a mask. The dorsolateral folds are lighter, usually golden or yellow. The upper surfaces of the thighs are barred. A light lip line is present. Ventral: The ventral surface is yellow or orangeish, darkening to red on the undersurfaces of the limbs. Concealed surfaces: The rear surfaces of the thighs have bright yellow spots. Eye: The upper portion of the iris is golden, darkening to brown on the lower half. Extremities: The feet are extensively webbed.
Tadpole: Tadpoles have a large, oval-shaped body and a rather short tail with small fins (Savage 2002). The mouth is very small (Savage 2002). The general coloration is dark brown, with heavy dark pigmetation on the tail (Savage 2002). The tadpoles of LIthobates warszewitschii grow quite large (Savage 2002). Metamorph juvenile: Juveniles are generally a metallic shade of green (Savage 2002).
Habitat: Lowland, premontane, and lower montane forest to 1740 m. Ecology: Lithobates warzsewitschii is commonly encountered along small streams in the forest (Savage 2002). Call: A low, soft trill (Greding 1972). Type locality: Unweit des Vulcanes Chiriqui, zwischen 6000′ und 7000′ Höhe, in einem feuchten, nie trockenen Klima von 12-14°R (Panama)
