Microcotyle eueides was first described by MacCallum & MacCallum (1913) from the gills of the striped bass Morone saxatilis (Moronidae), designated as Roccus lineatus in the original publication. Unnithan (1971) placed M. eueides in the new genus and subgenus Caenomicrocotyle as Caenomicrocotyle (Caenomicrocotyle) eueides.Unnithan, R. V. (1971).
