Dorsal: The dorsal surface is green, with rows of rather large, irregularly-shaped yellow spots running laterally down the back. A green middorsal stripe is also characteristic. Ventral: The ventral surface is transparent. The heart is visible, but the liver and digestive tract appear white. Eye: The eye is golden. Breeding season: Males call from the undersurface of leaves (Savage 2002). Egg: The eggs are green (Savage 2002). Habitat: The few individuals that have been encountered have been found in premontane forest. Call: A whistly "wheet", often repeated several times (Starrett and Savage 1973) Behavior and communication: Males guard egg masses at night, but hide away from egg masses during the day (Savage 2002). Type locality: Costa Rica: Provincia de San Jose: Canton Perez Zeledon: 0.5 km NE Alfombra: a place 16 km SW San Isidro de El General on the road to Dominical, 880 m Diagnostic description: The back has a well defined straight vertebral stripe green (in live), bordered on both sides by yellow stripes (the preserved specimens have a distinct dorsal stripe by pigment from purple and coffee). Usually without enlarged parotid glands, but if present. Head lacking ridges. No dorsal fold in the head or fleshy fold on the roof of the mouth. The belly is transparent, in living specimens, which will allow the internal organs. The bones are white in live specimens. The pericardium is colorless. A conspicuous lack tarsal tubercle, and the leg lacks tarsal fold. They have legs with five toes; no two elongated inner tubers, such as shovels, with a free margin. Without a pair of fleshy protrusions on the dorsal terminal finger region. They have a small digital groove, which separates the upper surface of the finger and bearing, at least in the two outer fingers and toes of the foot. Ventral disk lacks.

The talus and calcaneus are fused, the terminals are straight or T or Y. foma lack vomerine teeth. The membrane between the fingers of the hand ll-lll is not as extensive as between fingers III-IV, but restricted to the base of the toes. Habitat: They live in moist montane forest. Food: They feed on small insects like flies and crickets. Behavior: They are nocturnal and arboreal.
