Scinax rostratus — Köhler and Böhme 1996: 139 . Material examined. Table 1. A moderate-sized hylid frog characterized by a conspicuous acuminate and projecting snout in dorsal view, protruding in lateral view ( Duellman 1970 ). Scinax rostratus is readily distinguished from Scinax ruber and Smilisca sila (both species occurring in the Magdalena river valley) by the combination of its characteristic snout and coloration pattern (surfaces of thighs yellow or pale orange with black or dark brown markings in S. rostratus ; distinct black and white markings on posterior thighs in S. ruber ; blue spots on flanks and posterior surfaces of the thighs in S. sila ).
