Etymology authors: "generic name is based on the stem “amytha” as commonly used in ampharetid nomenclature". However, there is no such stem. Instead Samytha, a genus named by Malmgren using an ancient Greek female name, is the basis of a number of subsequent ampharetid names (Amphi/samytha, Eu/samytha, Micro/samytha, Neo/samytha).

Grammatical gender Paramytha is stated to be feminine [details]
