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; shibukawai: Named for Koichi Shibukawa, who collected and photographed the types of this new species,.
Eponymy: Dr Koichi Shibukawa is a Japanese ichthyologist who is a research scientist at the Nagao Natural Environment Foundation, Tokyo. [...] (Ref. 128868), visit book page.
