Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.; maculosa: Name from the Latin adjective 'maculosa' for 'spotted', referring to the distinctive, large black spots on the first dorsal fin of males; treated as a feminine nominative singular adjective..
