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; toshiyuki: Named for Toshiyuki Suzuki,; patronym in genitive case.
Eponymy: Toshiyuki Suzuki is a Japanese ichthyologist who teaches at Kawanishi-midoridai Senior High School. [...] (Ref. 128868), visit book page.
