Head broad, 1.1 wider than long, flat; nostrils protuberant, elliptical, angled; loreal region concave; rostral keel absent; snout long, in dorsal view presenting a narrower, short, round elevation, rounded in profile; eyes large, their diameter 40% of head length, round, prominent; tympanum small, its diameter 35% of eye diameter, distinct, slightly higher than wide; tympanic annulus prominent posteriorly; supratympanic fold heavy, extending from the posterior border of eye to above the arm insertion, wider posteriorly than anteriorly, covering upper part of tympanum.
In preservative, dorsum of body, head, flanks, shanks, tibia, and loreal region milky-brown covered with brown, irregular, diffused, small blotches; dorsum of front limbs, thighs, hands, feet, and all hidden surfaces orange brown covered by brown blotches; blotches on dorsum of front limbs well defined, dark, nearly forming reticulation pattern, forming dark continuous band along external edges of humerus and ulna; upper part of vent flap traversed by white blotches; narrow black band extends along supratympanic fold and canthus between eye and nostril; dark band on upper lip absent; dark pigment on posterolateral part of throat.
Entire ventral surface and concealed parts of the limbs pigmented, the pigment forming a reticulation leaving very numerous small rounded light areas; a dark line follows the supratympanic fold.
3)-the posterior end of the frontoparietals projects above the nape and the squamosal is outlined as a "structure" dorsal to the supratympanic fold and tympanum.
Older juveniles (UMMZ 23928-30) have dorsum of body, head, and limbs dark reddish brown with discrete black spots or mottled beige and black with discrete black spots; supratympanic, canthal, and labial stripes dark brown; flanks light brown with dark brown reticulations and small yellow spots; posterior surfaces of limbs dark brown with small yellow spots; tips of hands and feet brown or orange, with small, yellow spots on dorsum; belly dull purplish; ventromedial part of thighs pinkish, other parts yellow; throat and ventrum of arms dull yellow; throat covered with peppering black pigment; iris coppery.
They have tympanum distinct, large paratoids glands -separated from eyelid and tympanum by the supratympanic crests-, body surface covered by spiny tubercles and the basal webbings are serrated.
Two individuals were captured (CORBIDI 010284, 010286) and both exhibit shagreened skin on dorsum, tympanic annulus and tympanic membrane distinct, skin on venter weakly areolate, dorsolateral folds absent, small tubercles on the upper eyelid, coloration on dorsum red or reddish yellow, transversal black chevrons on dorsum, black labial bars and supratympanic stripe from the end of the eye to behind the tympanum and ventral coloration reddish.
Coloration in alcohol: Dorsal surfaces cream to brown, sometimes devoid of dark markings but usually with reddish brown to dark brown markings; maximally, pattern consists of interorbital bar, occipital W, and sacral and inguinal chevrons as well as slightly oblique limb bars; canthal stripe, supratympanic fold, and two labial bars reddish brown to brown; dark brown to black slanting bars on lower flanks, separating cream spots, similar pattern on anterior surfaces of thighs; posterior surfaces of thighs (and tops of thighs) bearing black bands, separated by cream areas; anal triangle prominent; ventral surfaces cream with faint brown mottling to heavily mottled and reticulated with brown; underside of shank dark brown with cream spots.
Coloration: In Preservative: Upper surface brown with tips of tubercles cream; suprascapular and presacral ridges cream, outline by darker brown; light interorbital bar indistinct, demarcated posteriorly by narrow dark brown bar; lip barred but light areas suffused with some brown pigment; supratympanic ridges cream, bordered by dark brown paired dark suprascapular and supra-axillary dark spots; limbs weakly barred with dark bands; posterior thigh surface same color as dorsum, anterior surface light tan; paired paracloacal light stripes present; chin, throat and venter pale cream punctuated with scattered melanophores; undersurfaces of limbs pale cream.
Tympanum little less than half the eye diameter, separated from eye about 1/2 its horizontal length; supratympanic fold not evident; tympanic ring inconspicuous, with anterior ridge slightly elevated.
Coloration in alcohol: Upper surfaces slate with little indication of pattern (scattered darker markings on lower back, traces of a pale interorbital bar, fragments of limb bars); side of head darker without facial markings except for cream line along upper lip (Figure 2); brown supratympanic stripe; brown blotch on posterior flank, extending into groin and along of thigh; comparable blotch over most of posterior surface of thigh, bearing cream flecks or not; venter cream, heavily mottled with brown; throat somewhat darker than venter; underside of shank brown with cream flecks or not.
Coloration in alcohol: Brown above with interorbital bar/ triangle and some vague spots on body; limb bars of legs evident in female (not males), edged with cream and oblique to axis of shank; canthal stripe and supratympanic stripe dark brown; pair of pale subocular bars; slanted bars on flanks; venter nearly white but some concentration of brown stippling on throat of MHUA 1822 (with white raphe) and the holotype; venter with few clusters of stipples; posterior surface of thigh with dark spots near upper edge--rest of surface brown with diffuse cream spots.
