Rhinella alata — Frost et al. 2006: 365 Material examined. Table 1 . Rhinella alata is a small-sized toad with skin of dorsum bearing a mixture of warts, pustules and minute tubercles; supraorbital crests low and thick, continuous with preorbital crests; dorsal coloration ranging from light gray or brown to dark gray or brown, with irregular black and yellowish marks (a mid-dorsal line is usu- ally present) and coloration of ventral surfaces cream to yellowish-cream with irregular darker marks arranged in diverse patterns ( dos Santos et al. 2015 ). Populations of Rhinella margaritifera species group distributed on Magdalena river valley have commonly been referred to as R. margaritifera (see Burbano et al. 2016). Nevertheless, although R. alata is closely related to R. margaritifera (distributed in the upper Amazon basin of Peru and Ecuador ), this species may be easily distinguished by dif- ferences in body size ( R. margaritifera being significant larger than R. alata ) and the relative size of the cranial crest (larger in R. margaritifera than in R. alata ).
