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; rubrimaculata: Name as an adjective from the Latin 'rubra' for red and 'macula' for spot; referring to the
distinctive red spots on the head and body.
