the parieto-supraoccipital and nuchal plate; differs from C. habrosus by possessing a conspicuously thick transversal black bars on caudal-fin lobes; differs from its most similar congeners (C. carlae, C. ehrhardti, C. longipinnis, C. paleatus), by the absence of small plates on the ventral surface of the trunk; with a distinct rounded snout (Ref. 129023). |
