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; irrasa: From the Latin irrasa meaning unpolished or unshaved, in reference to the indiscrete nature of the pigmentation pattern of the head and trunk (Ref. 5289).
