==Appearance and anatomy==
''Rhinodoras'' species are distinguished from other doradids by a unique combination of coloration (sides darkly mottled, usually with wide dark bars, light mid-lateral stripe absent) and lip shape (labial tissue thick, fleshy, considerably expanded at corners of mouth forming rounded flap-like extensions with entire margins, all surfaces rugose with low, rounded, and tightly spaced papillae, and distal margin of lower lip draped over bases of outer and inner jaw barbels, at times nearly encircling the latter).
