Description of the neotype Body robust; head triangular, slightly wider than long; snout short, canthus rostralis rounded and vertically truncated. Eyes protuberant; eye diameter larger than interocular distance; interocular distance larger than internarinal interval. Round tympanic annulus almost concealed, approximately half the size of eye diameter. Commissural glands present, oval, approximately the same size of eye diameter. Vomerine teeth absent. Dark vocal sac. Fingers free; relative length of fingers: 3>4>1>2; two not-darkened palmar tubercles. Femur length less than tibia length; sum of femur length and tibia length longer than foot length. Toes free with cutaneous edge and rudimentary interdigital basal membrane; two metatarsal tubercles, inner metatarsal tubercle pointed and outer metatarsal tubercle shovel-shaped; relative length of toes: IV>V=III>II>I. Lumbar glands large, oval, one and a half times the size of eye diameter. Vocal sacs single, median and subgular. In life, dorsally brownish with large almost symmetrical dark spots. Dark transverse bands on upper surface of arms and legs. Yellow lumbar glands with a black central ocellus covering 60% of the gland. Brilliant red-orange spots on the groin and around lumbar glands. Dark palms and soles, with whitish palmar tubercles. Dark vocal sac with the rest of ventral body surface whitish and mild dotted dark. Iris gold with black reticulations. Measurements (in mm): Snout-vent length 34.4 ; maximal head width 13.6; head length 11.5; snout-eye distance 5.0; internarinal distance 1.9; interocular distance 2.7; eye-narinal distance 2.7; rostronarinal distance 3.2; eye diameter 3.6; arm length 16.1; length of III finger 4.6; femur length 15.0; tibia length 15.8; foot length (including tarsal length) 22.5; length of III toe 5.2; length of IV toe 9.1. Larval morphology At stage 36 (Gosner, 1960) mean total length is 36.4 ± 1.3 mm, body is globose, depressed. The body length is about 40% of total length, body shape is oval in dorsal view with a constriction behind the cephalic region and the maximum width is placed at the posterior portion of the head, behind the eyes. Ventral contour is slightly convex in lateral view and dorsal contour is rounded, uniformly convex from the anterior edge of the oral disc to the eyes, and then slightly convex to the beginning of the dorsal fin. The snout is truncated, trapezoidal in dorsal view, and rounded in lateral view. The nostrils are rounded and placed in a depression; they are dorsolaterally located, slightly closer to the eyes than to the tip of the snout, more visible dorsally than laterally. Their openings are directed dorsally and slightly to the front and present a slightly elevated marginal fleshy rim. The eyes are small and dorsally located, dorsolaterally oriented, and not visible in ventral view. The pineal end organ is visible as a less pigmented spot between the anterior edges of the eyes. The spiracle is single, lateral, sinistral, short, posterodorsally directed, and placed in the second third of the body. The spiracle inner wall is fused to the body wall except for the very distal end, which folds to delimit the spiracle opening. Spiracle opening is oval, placed below body midline, being its diameter smaller than the tube diameter; it is visible laterally and ventrally. The intestinal ansa was observed approximately at the center of the abdominal ventral surface or displaced to the left behind the spiracle opening. The vent tube is medial; it starts at midline but opens to the right in 60% of the examined specimens or to the left in the others, due to a variable folding of the ventral fin at its origin. A medium-sized saccular structure underlies the limb buds and encloses the vent tube. The tail is medium-sized, and both fins are slightly shallower than body height. The dorsal fin originates on the body-tail junction and its free margin is regularly curved, convex, with the maximum height at the middle length of the tail. It is as high as the ventral fin, which originates from the saccular structure, and presents a smoothly convex free margin. The tail axis is straight, and the tail smoothly stretches towards the tip in it last half, ending bluntly rounded. The tail musculature does not reach the tail end, and myomeres are more visible in the proximal half. Neuromasts are very small and hardly visible, even with the help of magnification and after staining the tegument with methylene blue. The oral disc is anteroventral, medium-sized, laterally emarginated, and has a large dorsal gap. Marginal papillae are arranged in a single alternated or double row, except in the ventral region in which the row is single for approximately the length of P3. Papillae are simple, small and longer than wide, sub-conical. Sub-marginal papillae are absent. Jaw sheaths very robust, finely serrated, heavily pigmented distally for about 2/3 to Å? their length. The free margin of the upper jaw sheath is widely arch shaped, whereas that of the lower jaw sheath is V-shaped. Labial tooth row formula is 2(2)/3(1). The gap in A2 is wide, almost one third the length of the row, and the anterior edge of the upper jaw sheath is placed within it. The gap in P1 is narrow. The length of P3 is about half the length of the other rows.
