Common name

Golfito Robber Frog

Identification

Adult

Species description based on Savage (1975), Campbell and Savage (2000) and Savage (2002). Males and females differ in size. Males to 44 mm, females much larger (to 80 mm).

Dorsal

The color of the dorsal surface is grey or brown with darker blotches. Dark bars are present on the arms and legs. Dorsal surface very bumpy.

Ventral

Ventral surface is smooth and white; large individuals sometimes have a yellowish-green tint towars the rear.

Concealed surfaces

Both the groin and the rear surface of the thigh are mottled dark brown and light yellow.

Extremities

Feet have extensive webbing. The webbing, toe fringes, and large toe pads may help this species (as well as other stream-dwelling species) cling to slippery rocks (Savage 1975).
