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; variola: Named for the spots on the first dorsal spine and filament, Latin variola meaning spotted.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 9 - 10; Spine anali: 1; Raggi anali molli: 8 - 9. This species is most closely related to the Eviota prasina complex, but differs from it in the following characters: usually A I,9 rather than I,8; pelvic fin often with a rudimentary fifth ray, which is usually absent in E. prasina; first filamentous dorsal spine with alternating dark and light spots to tip; occipital spots dark, prominent in adults but faint in young; dark peduncle spot more circular than chevron shaped; dark subcutaneous bars on posterior part of trunk 5/5, not 4/5 (Ref.
Body shape (shape guide): fusiform / normal.
The smallest gravid female 1.74 cm SL (Ref. 5293). Found in coral reef, benthic (Ref. 75154).
