description
Description of the holotype. UFMT 13716, Adult male (Figure 4). SVL 42.9 mm; head wider (16.5 mm) than long (15.2 mm) at the angle of jaws. Snout rounded in dorsal view, acute with fleshy ridge extending to tip of snout in lateral view. Cephalic crests weakly developed, only the supraorbital, parietal and supratympanic crests present; canthus rostralis without crests, concave; interorbital and internarial region flat, nostrils protuberant directed dorsolaterally; eye to nostril distance equal to eye diameter, larger than internarial distance; upper eyelid width about 80 % of eye diameter. Tympanum distinct, large, almost rounded; its horizontal diameter representing 93 % of the vertical diameter and equal to internarinal distance. Corner of mouth angular, without bony knobs at the lower angle of jaws. Vocal slits present, lateral to the tongue; choanae small, ovoid, lateral, widely separated; tongue free, not notched behind. Paratoid glands small, triangular. A dorsolateral line of small tubercles extends from the posterior border of the paratoid gland to the groin. Vertebral apophyses absent. Skin on dorsal and ventral surfaces granulose, with scattered conical tubercles. Small tu

diagnosis
Diagnosis. Rhinella parecis sp. nov. is diagnosed by the following combination of characters: (1) snout-vent length range 40.7 – 53.5 mm in males and 44.9 – 54.8 mm in females; (2) snout rounded in dorsal view, acute with fleshy ridge extending to the tip of the snout in lateral view; (3) canthal and pre-orbital crests absent; (4) supra-orbital, parietal and supra-tympanic crests present and low; (5) dorsolateral row of tubercles present; (6) bony protrusion at the angle of jaws absent; (7) tympanum evident; (8) vertebral apophyses absent; (9) toes half-webbed. Comparison. Among the species of the Rhinella margaritifera species group (characters in parenthesis), the absence of canthal and pre-orbital crests distinguish Rhinella parecis sp. nov. from R. alata, R. gildae, R. hoogmoedi, R. margaritifera, R. martyi, R. ocellata, R. paraguayensis, R. roqueana, R. scitula, R. sebbeni, R. sclerocephala, R. stanlaii and R. yunga (canthal and pre-orbital crests present). Rhinella parecis sp. nov. is distinguished from R. alata by larger snout-vent length (SVL), dorsolateral line of tubercles weak, and triangular paratoid glands (SVL 37.54 – 39.20 mm in males, 37.78 – 49.69 mm in females, ma
