Etymology: Amioides: Gender of genus not indicated by Smith and Radcliffe; a combination of Greek Amia, a feminine noun, for a kind of fish, with the suffix '-oides' meaning like or resembling; thus governed by the gender of the noun, in this case the compound word is feminine; polyacanthus: Vaillant suggested the name polyacanthus based on the canine teeth and spines in the first
dorsal fin that differed from Cheilodipterus species (however, no name derivation was given by him). Fraser (2013) assumed that the masculine Greek noun 'akanthos' meaning prickly plant, as acanthus and the prefix 'poly-' meaning many or very; treated as a noun in apposition.
