Diagnosis

A species of the Hypsiboas albopunctatus group (sensu Faivovich et al. 2005) distinguished from other species in the group by the following combination of characters: maximum SVL, 70 mm in males, 81 mm in females ( Lutz, 1973; Cei, 1980); body robust; snout long, acuminate in dorsal view, rounded and protruding in profile; canthus rostralis slightly rounded in cross­section; loreal region concave; tympanic membrane and tympanic annulus distinct, round, its diameter about three­fifths eye length; supratympanic fold prominent, covering upper edge of tympanic annulus, reaching slightly behind insertion of arm; vomerine odontophores prominent, separated medially, between choanae; hind limbs long, slender; tibiotarsal articulation reaching beyond tip of snout; heels overlapping when limbs flexed perpendicular to axis of body; tarsal fold and tubercles on outer edge of tarsus absent; weak ulnar folds present; axillary membrane absent; fingers with basal webbing; toes about four­fifths webbed; well­developed, round terminal discs on fingers and toes, slightly smaller on toes; single distal subarticular tubercle under fourth finger; enlarged pollex rudiment with slightly projecting bony spine in adult males; nuptial excrescences absent in males; skin on dorsal surfaces smooth, with or without small tubercles; skin on throat tuberculate; skin on venter and ventral surfaces of thighs strongly granular; distinct transverse fold on chest; dorsal surfaces tan, pale grey or brown, with or without indistinct irregular dark transverse marks and flecks and/or small cream spots; loreal and tympanic region brown; ventral surfaces cream, sometimes with indistinct and irregular brown marbling and spotting on throat and chest; posterior flanks and hidden surfaces of thighs white to greyish­cream with bold dark brown spots or vertical bars.

Description of neotype

An adult male; body and extremities long and slender; head slightly longer than wide. Dorsal skin and throat smooth, belly and groins areolate, flanks warty, with low elongate warts; dorsal folds absent; supratympanic fold prominent, from posterior margin of the upper eyelid to the level of the arm insertion; tympanic membrane large, conspicuous, round to slightly oval; tympanic annulus thin, almost complete, but hidden in its dorsal margin; snout round in dorsal view, round to subacuminate in lateral profile; canthus rostralis sharp, concave in dorsal view; loreal region slighlty concave; narines slightly prominent, dorsolaterally oriented; tongue more or less circular, weakly bifurcated behind, barely free posteriorly; vomerine odontophores large, transverse, between choanae, almost in contact with each other and with choanae; about ten small vomerine teeth on each odontophore; choanae large, triangular, separated by a distance twice their diameter. Thenar tubercle large, elongate, almost twice as large as palmar tubercle; palmar tubercle small, low, cordiform; supernumerary tubercles abundant (up to five on a finger), round, smaller than subarticular tubercles; subarticular tubercles round, prominent; interdigital membrane between Fingers II­III­IV basal; finger lengths 3>2>1>4; discs large, round to slightly oval; prepollical spine present; no tubercles on heel and tarsus; inner metatarsal tubercle large, low, oval; outer metatarsal tubercle almost inconspicuous; subarticular tubercles large, round; supernumerary tubercles abundant, round, small, inconspicuous; toes with interdigital membrane well developed, webbing formula, I1­ 2 II1­ 2 III1 1/2­ 2IV 2­ 1V; toe discs large, round; toe lengths 4>3>5>2>1.

Coloration in alcohol

Dorsal surfaces dark brown with small, diffuse, irregular darker marks; flanks cream with vertical, diffuse, brown bars. Throat cream with dense dark brown mottling, chest with less mottling; belly immaculate cream; ventral surfaces of limbs cream; anterior and posterior surfaces pale brown with darker vertical bars, more contrasted on the posterior surface; ventral surfaces of hands and feet brown; tympanic membrane dark brown, supratympanic fold dark brown to black.
