Ventral: Ventral surface is yellow, typically with brown mottling, including the throat. Concealed surfaces: Rear surfaces of the thighs are dark brown or black with small distinct yellow spots. Extremities: Feet are extensively webbed. Habitat: Premontane forest between 950-1800 m. Ecology: Individuals are usually found perched on rocks in or near very fast-moving streams (Campbell and Savage 2000). This species is probably more active at night (Campbell and Savage 2000). Karyotype: 2N = 20 (Campbell and Savage 2000) Type locality: Quebrada Fortuna, 19 km N San Isidro de El General, 1700 m, Cantón Pérez-Zeledón, Provincia de San José, Costa Rica. This locality is in Tropical Premontane Rainforest at approximately 9° 28′ 25″ N, 83° 41′ 42″ W Diagnostic description: Moderate size (males 50 mm, 81 mm Socket); back coffee with dark spots; vientre pale yellow, usually labeled muy pigment coffee; Muslera surface it later mottled yellow to pale and coffee; digital discs large (Savage 2002).
