Adult: Species description based on Savage and Myers (2002) and Savage (2002). A very large frog with a large head (males to 44 mm, females to 69 mm). Dorsal: Dorsal coloration is dark brown, dark grey, or black. The dorsal surface is extremely bumpy and warty, the tips of which are white in young individuals but darken with age. Hourglass or chalace-shaped ridges, outer edges outlined by light stripes, are also present on the upper back. Prominent crests are present just behind the eyes. The upper surfaces of the thighs are barred; the barring continues onto the rear surface. Ventral: Ventral coloration is mottled brown with white and red. The undersurfaces of the thighs are yellowish or orange. Concealed surfaces: Rear surfaces of the thighs have alternating bars of black and bright scarlet red. The groin is marked with bright white and black. Eye: The iris is black. Upper eyelid has many bumps or warts. Extremities: Feet are not webbed. Metamorph juvenile: In juveniles, white replaces red on the rear surfaces of the thighs and the undersides of the legs and groin are orangey-red (Savage 2002). Habitat: Lowland and premontane forest to 1220 m. Ecology: Adults may be found in leaf litter (Savage and Myers 2002). Call: Craugastor rugosus probably does not call (Savage 2002). Karyotype: 2N = 20 (DeWeese 1976) Type locality: Chiriqui Diet: Adults are probably sit and wait predators. They eat mostly beetles, but may also consume lizards and frogs (Savage and Myers 2002). Diagnostic description: The standard length of adult males is 30 to 44 mm and females is 35 to 69 mm. This is a large and extremely rough, and the broad head species. It is easily recognized by having black bars alternating with bright scarlet (white youth) to the rear thighs and narrow disks on fingers, and lack webbing (Savage, 2002). Reproduction: Encapsulated produce eggs which are laid in terrestrial conditions, with direct development (no tadpoles) (Savage 2002). Feeding: Possibly eat insects and small frogs and lizards (Savage, 2002). Behavior: They are nocturnal and terrestrial. Overnight are at the entrance to their shelters waiting for prey; during the day are in their shelters (Savage, 2002). Distribution in Costa Rica: In the lower and middle central and southern Pacific slope of the land, between 10 and 1,220 m. Lift (Savage 2002). Distribution outside Costa Rica: It is found from southwestern Costa Rica to southwestern Panama (Savage, 2002). |
