Haddadus binotatus (Spix 1824)

Diagnosis Distinct toe disk with circumferential grooves and lacking toe webbing or fringes. With distinctive rows of almost parallel ridges on the dorsal surface of the body.

Present in the Atlantic Rain Forest of Brazil from south of the Bahia state to north of Rio Grande do Sul State.

Adult morphology Vomerine teeth in large, slanting, well-separated arcs behind the choanae; tongue slightly more than one-half the width of mouth-opening, rounded, with a notch in its free posterior border; snout long, bluntly pointed when seen from above and in profile, the upper jaw projecting considerably beyond lower; nostrils lateral, their distance from end of snout one-half their distance from eye, separated from each other by an interval equal to three-fourths their distance from eye. Canthus rostralis sharp; loreal region flat, the upper lip flaring outwards below it. Eye large, very prominent, its diameter four-fifths the length of snout; interorbital diameter slightly greater than width of upper eyelid, 1 1/2 times the distance between nostrils. Tympanum distinct, one-half the diameter of eye, separated from eye by two-thirds its own diameter. Fingers rather short, free, second shorter than fourth, first longer than second and fourth, all with rounded tips, which are only slightly dilated ; a heavy pointed elongate pad at base of first finger and a flattened oval one on palm; all metacarpal tubercles very greatly developed; toes moderately long, free, with slightly dilated tips, third slightly longer than fifth and reaching to base of antepenultimate phalanx of fourth; a small conical inner metatarsal tubercle and a rounded, flat outer one; metatarsal tubercles very well developed, those below the proximal joints being larger than the inner metatarsal tubercle; no tarsal ridges, instead a row of weak round or elongate glandules on outside of tarsus. Body rather stout, in postaxillary region equal to greatest head width. When hind leg is adpressed, heel reaches a little beyond tip of snout; when limbs are laid along the side, knee and elbow greatly overlap; when hind legs are bent at right angles to body, heels overlap. Skin of upper parts minutely glandular, with 8 to 10 fine, broken, sinuous granular ridges from posterior half of each eyelid to the sacral region; some small granules above coccyx, extending onto posterior femur; a narrow, distinct supratympanic ridge, with rounded heavy glandules at corner of mouth and smaller ones in front of tympanum. Venter smooth, with a prominent ventral disk. No apparent external vocal sac. Color in alcohol: Dorsum pale olive-yellow; a dark brown stripe along canthal region; a pair of light brown spots where the glandules end at sacrum; three pale gray crossbars on femur and tibia, and one or two fainter ones on forearm; upper lip pale gray, with traces of light diagonal bars in front of and behind the eye; venter immaculate pale buff. Color in life: Upper surface clay color tinged with vinaceous-buff. A clove-brown stripe along the canthus, ending behind ear, and a clove-brown stripe along outer side of tibia. Pupil gold above, with a brown line through it; below more coppery and greenish, the entire area sprinkled with fine black dots.

LC. Least Concern.

Haddadus binotatus (common name: clay robber frog) is a species of frog in the family Craugastoridae. Haddadus binotatus is a very common frog. It inhabits primary and secondary forest and forest edges. It is usually found in the leaf-litter on the forest floor, or on leaves in low vegetation inside the forest.

It is endemic to the Brazilian Atlantic forest and most dominantly found in the states of Rio de Janeiro and Espírito Santo. The density of leaf eating frogs like Haddadus binotatus is higher in Central America than southern America. The Haddadus binotatus is a direct-developing frog and the most abundant species in the community.

Female frogs reach 64 mm (2.5 in) snout–vent length. The female of the species were larger than the males, which may result from the production of larger eggs.

Haddadus binotatus es una especie anfibio perteneciente a la familia Craugastoridae.​
