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; nigramembrana: Name an adjective combining the Latin 'nigra' (black) and 'membrana' (membrane), referring to the distinctive black pigment on the opercular membrane.
