Itapotihyla langsdorffii (Duméril & Bibron 1841)

Ano todo

Diagnosis 1) size large, sexual dimorphism moderate; snout-vent length 70-77 mm in males, 89-99 mm in females. 2) skin or dorsum of males bearing small conical tubercles; 3) skin of flanks tubercular: 4) web extending to base of penultimate phalange of third finger; 5) dorsum olive-brown or greenish gray with irregular pattern of darker shades; 6) throat and chest white; belly and ventral surfaces of thighs yellowish orange; 7) lips unmarked; 8) flanks bluish gray; 9) dermal roofing bones of skull, exostosed and coossified. Can be distinguished by the presence of scalloped dermal folds on the outer edges of the hands and feet, a row of tubercles on the posterior edge of the jaw, tubercles on the flanks, and white subanal folds.

In Brazil the geographic range is wide and continuous through the Atlantic Rain Forest, extending from central Bahia state (municipality of Mata de São João) to northern Rio Grande do Sul state (municipality of Itati). Also, there is an isolated population inhabiting the Atlantic Semi-deciduous Forest at the western zone in the states of Paraná and Santa Catarina, between Paraguay and Argentina border, and more recently was recording from a locality in the Sergipe state.

Adult morphology Body elongate, slender; head flat, snout forming an obtuse angle, rounded at the tip; tympanic area and posterior edges of head vertical; canthus rostralis thick, blunt; loreal region concave; nostrils subcanthal, oblique; eye prominent, its diameter equal to distance of its posterior rim to the nostril; tympanum large, round, about 213 the eye diameter; interorbital space greater than the internarial; vomerine teeth forming two short separated patches between the choanae. Hind leg long, heel reaching tip of snout when leg adpressed; hands and feet large, with very large disks; a pollex rudiment at the base of the first finger, and double or enlarged subarticular tubercles on the base of fourth finger; large, pointed inner metatarsal tubercle, the outer small, rounded; fingers very shortly webbed; web on feet reaching the terminal toe disk; skin of dorsum bearing small conical tubercles; flancs tuberculate; posterior part of venter and thighs granular, as if paved; few conspicuous tubercles on the heel. Dorsum olive-brown, or greenish-gray with irregular pattern of darker shades; flanks bluish-gray; throat and chest white; belly and thighs yellowish-orange. Vocal sacs lateral, double, white, much pleated. Larval morphology Stages 39Â?40 (Gosner 1960). Mean total length 53.1 (sd = 2.72 mm). Body robust and elongated, elliptical in lateral, dorsal, and ventral views; snout rounded in dorsal view and truncated in lateral view . Body length approximately 34% (32.6Â?36%) of total length; body width about 55.3% (55.1Â?55.4%) of body length. Nostrils rounded, closer to eyes than to snout, located and oriented anterodorsally; internostril distance about 65.4% (61Â?70.6%) of interorbital distance; eyes located laterally; eye-nostril distance approximately equal to eye diameter; spiracle single, sinistral, short and tightly attached to body, with its opening situated on the body middle third, slightly below the midline of body, and posterodorsally oriented; spiracle inner wall absent; anal tube dextral, short and wide, attached to ventral fin. Tail ca. 2.0 mm higher than body; tail muscle height about 29.3% (27.1Â?35.5%) of tail height; dorsal fin slightly higher than ventral fin; dorsal and ventral fins originating at body-tail junction; tail musculature nearly reaches tail tip, which is obtusely pointed. Oral disc anteroventral, not emarginated, its width approximately 49.5% (47.4Â?52.2%) of body width; two rows of marginal papillae, with a medial gap on upper lip; a few scattered submarginal papillae on ventrolateral portions; labial tooth row formula 2(2)/6(1) in younger tadpoles (stages 35Â?36); the sixth posterior teeth row is fragile and laterally fragmented. On stages 38 to 40, we no longer considered it a teeth row, because it is completely fragmented and denticles are scarce, so labial tooth row formula becomes 2(2)/5(1); upper jaw sheath arched, nearly "U"-shaped, and lower sheath "V"-shaped. Coloration: general color pattern in life is greenish brown, with scattered black dots over body and tail. A roughly "U"-shaped set of cream blotches is observed under the eyes. A grayish brown stripe is observed from the anterior margin of eyes to mouth, and a cream stripe from the anterior margin of eyes to nostrils. Tail musculature is cream, with a longitudinal black stripe from the beginning to the end of tail. A narrow line of small black dots marginates tail musculature dorsally. Fins are reddish and translucent, with small, scattered black dots. Venter is cream. Iris is golden, divided horizontally by a thin black line. Legs have the same color of body, with black blotches mainly on toes. In 5% formalin, body remains greenish brown, with scattered black dots on dorsum. Venter and fins become transparent, and legs are cream. Black and cream coloration are maintained

Itapotihyla is a genus of frogs in the family Hylidae. It is monotypic, being represented by the single species Itapotihyla langsdorffii, commonly known as the ocellated treefrog. It is found in the Atlantic Forest biome of Brazil, with an isolated population in eastern Paraguay and adjacent Brazil and northeastern Argentina.
