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; deminuta: Name from Latin adjective 'deminuta' meaning small, diminutive. Both scientific and common names refer to the tiny size and reduced morphology of this species; noun in apposition.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 8 - 9; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 7 - 8. This species is distinguished by the following set of characters: no sensory pores on head; dorsal/anal formula 8/7; branched pectoral-fin rays; fifth pelvic-fin ray absent; caudal peduncle has a dark spot, typically restricted to above lateral midline; caudal peduncle with a dark blotch over the middle, and a dark bar or crescent over its posterior margin and base of caudal rays (Ref. 94084).
Body shape (shape guide): elongated; Cross section: oval.
Collected from coral and rocky reefs at depths from 3-41 m; very abundant at Nuku Hiva, where nearly 250 individuals were captured in a single collection between 3-6 m depth (Ref. 94084).
