Adult: Species description based on Duellman (2001) and Savage (2002). A small, rather squat treefrog: males to 32 mm, females to 35 mm. Dorsal: Dorsal coloration ranges from yellow to orange to olive brown. Some darker markings may be present, including an indistinct brown line that runs from behind the eye along the side of the body towards the groin, a dark spot on the top of the head, and a dark bracelet at the wrist. The skin of the dorsum is covered in very small bumps. Ventral: The venter is white and slightly bumpy in appearance. Eye: The iris is coppery red. Extremities: The fingers and toes are relatively short and thick, and end in large terminal discs.
Breeding season: Males call throughout the rainy season (Savage 2002). These frogs breed in bromeliads (Savage 2002). Tadpole: The tadpole body is flattened, with a long, thin tail with low tail fins. Tadpoles are grey, with a lighter ventral surface and tail fins.
Habitat: Montane forest to 2650 m. Ecology: These frogs are commonly found in bromeliads (Stuckert et al. 2009). Call: The call has been described by Lindquist and Cossel (2007). Behavior and communication: Although this behavior has not been directly observed, females probably feed tadpoles unfertilized eggs (Savage 2002). Type locality: Volcan Barba, [southwestern slope, Cantón de Santa Barbara, Provincia de Heredia,] Costa Rica, a little above the farm of Manuel Acosta, 2140 m
