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.; kermadecensis: Named for its type and only known locality, the Kermadec Islands of New Zealand..

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 8 - 9; Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: D usually VI + I,10; A usually I,8; most pectoral-fin rays branched; cephalic sensory-pore system pattern 1 (terminal lateral canal pore present); males with first dorsal spine filamentous, base of pectoral fin with 2 spots (darker than body color or much lighter than body color), lower spot usually smaller than upper and sometimes obscure; 4 segmented pelvic-fin rays plus a rudimentary fifth ray present, pelvic rays partly separated, connected about one-third to one half between segmented rays 2-4 and almost completely connected to tip between spine and first ray; rudimentary fifth pelvic ray bound in membrane to fourth ray; subcutaneous bars on lower trunk behind anus usually lacking in preserved adults; nasal tubes short, tips of tubes with thin black ring, dorsal, anal and caudal fins usually grey to black; dorsal fin with some light spots; vertebrae usually 26 (Ref. 93112). Dorsal to anal fin-ray formula 10/8 (Ref. 116739).
Found in rocky reefs (Ref. 93112).
