Diagnostic Description

provided by IABIN
Adult morphology Snout-vent up to 70 mm: exceptionally 80 mm in some female s from northern Brazil. Head as large as wide; snout pointed in dorsal profle, rounded in lateral profile, the upper jaw projecting beyond the lower. Nostrils laterally located, closer to the tip of snout than to the eye, and separated from each other by a space almost equal to their distance from the eye. Internarial interval slightly narrower than interocular distance, which is equal to the width of the upper eyelid. Maxillary teeth well-developed. Vomerine teeth in two short, heavy shaped, spaced series between and behind the choanae. Tongue oval in shape lightly notched behind. Canthus rostralis rounded, evident; loreal region slightly concave, nearby vertical up to the right border of the upper lip. Eye prominent, large, being its diameter equal to its distance from the nostril. Tympanum distinct, 3/4 of the eye diameter. Supratympanic fold evident, extending over axilla down the sides. Fingers webbed at the base; rate of the finger lengths: I-II-IV-III. Disk of the third finger covering about 1/2 of the tympanic arm. A rudimentary pollex evident. A faint but evident glandular ridge along the outer side of forearm. Toes 3/4 webbed, the disk of fourth covering 1/3 of the tympanic area. An inner metatarsal tubercle evident; no outer metatarsal tubercle. A narrow low ridge along jnside the tarsus, and a wider one on the outside. When hindleg is adpressed, heeI reaches far beyond the tip of the snout. When the femurs are bent at right: angles to the body, the tibia-tarsal articulations largely overlap. Dorsal skin very minutely granular on the throat, but slightly granular on the chest and heavily granular on belly and lower surface of thighs. A deep skinfold across the chest and another one anterior to that, where the external vocal sac ends. Dorsally pale grayish or creamish gray scattered with dilute dark marblings, and coarsely transverse bars in the interocular region. Faint wide transverse bands on the upper surface of limbs. Narrower bright dark bars on the anterior surface of thighs, extending on the groin. Heavy irregular dark brown bands on the posterior region of the thighs, extending on the inner tibio-tarsal region and alternating with pale bluish or violet bands. Ventrally yellowish olive, whitish or greenish, with the lower labial border immaculate and frecuently a faintly spotting on the throat and chest. Belly immaculate. Lower surface of foot and tarsis slate colored, with a paler line following their low glandular ridges. Larval morphology The body is oval, slightly tnlncate posteriorly, about 1/3 of the totnl length. The eyes are large, dorsally located, at a distance from the end of the snout equivalent to 1/4 of the length of the bodv. The iris is light brownish, crossed by two dark bands at the center of the pupil. Interocular distance equal to the eye diameter. Bean-shaped nostrils almost 1/2 of the eye diameter, with a central operculum. Spiracle sinistral, opening laterally and posteriorly, at 3/5 of the snout-vent distance; anal opening dextral. Dorsally yellowsh brown, light on the venter. Tail marbled with indistinct dark spots, especially on the ventral fin After the stage 40 the general color pattern is .greenish. Mouth with wide marginal fold with a single row of papillae; a short, median portion of the upper lip is bare. Weak horny beaks, slightly serrated. Tooth rows formula: 2 /3(1) or 2/3.
