Etymology: Melamphaes: Greek, melan, -anos = black + Greek, amphi = both side (Ref. 45335); succedaneus: Name from Latin 'succedaneus', translated into Russian as 'replacing', which indicates that it replaces in the eastern part of the Pacific Ocean the closely related species of the complex M. longivelis from the Indian Ocean and western part of the Pacific Ocean.
