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; lentiginosa: Name from Latin adjective 'lentiginosus' meaning full of freckles, referring to the many tiny dark spots covering the yellow head and body: treated as a feminine nominative singular adjective.
