Adult: Species description based on Savage (2002). A medium-sized frog with a pointed snout. Males to 48 mm, females to 66 mm. Dorsal: Dorsal coloration ranges from light to dark brown (sometimes with a pinkish hue), almost always with a darker hourglass shape in the center of the back. Some dark lines running laterally along the dorsum or sides may also be present. The dorsal surface is slightly granular. The upper surfaces of the arms and legs have dark barring. Ventral: Ventral coloration ranges from solid white to white with much brown mottling. The ventral surface is smooth. Concealed surfaces: The rear surface of the thighs and the groin are reddish in color, without any spotting or mottling. Distinguishing characteristics: Craugastor noblei has a dark eye bar than extends beyond the arm onto the lateral surface of the body. Eye: Iris is golden with brown in the lower half. Extremities: Feet have almost no webbing.
Habitat: Lowland and premontane forest to 1200 m. Ecology: While many species of the genus Craugastor rely on crypsis to escape predators, Craugastor noblei is much more flighty and likely to jump upon approach (Cooper et al 2008). Call: Craugastor noblei does not call (Savage 2002). Type locality: Guápiles, Costa Rica
Diagnostic description: The legs have a thin webbing that extends at least to the first (proximal) subarticular tuber at least one side of the fingers and II usually in the II and IV. Their paws are tiny webs between the fingers lll and lV, extending at most slightly beyond the first subarticular tubercle of each toe. The tip of the fingers (especially fingers III and IV) has clearly enlarged discs or bearings without cranial crests. The head is narrow and measures 30 to 43% of standard length. The bearings of the outer fingers (III and IV) of the hands are much larger than those of the fingers and II. The outer fingers and finger outside of the leg are usually truncated and sometimes marginalized. The heel is smooth.
The upper thigh color is pale to reddish reddish impregnated in live specimens, with a dark eye mask defined in the yellowish brown. The start arm and leg is usually red in live specimens. The plant has low paw plantar tubercles, but defined. The dorsal skin is smooth. The upper lip is light gray, yellow or brown, the same color as the dorsal part and has a definite glandular fold which continues from the supratympanic fold and extending posteriorly at least one third of the body length.
Adult males lack nuptial pads on the thumbs and vocal slits.
The maximum standard length of males is 42 mm. and females is 60 mm.
Habitat: They live in evergreen forests and premontane low lands.
Reproduction: Encapsulated produce eggs which are laid in terrestrial conditions, with direct development (no tadpoles) (Savage 2002).
Behavior: During the day is in the litter, and hours perched on the low understory vegetation.
Distribution in Costa Rica: In the lowlands and the middle Atlantic slope, and the center and south of the Pacific slope, between 4 and 1,200 m. Lift (Savage 2002).
Distribution outside Costa Rica: Are east of Honduras, Costa Rica, Nicaragua and Panama.
