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.; taeiae: Named for Sue Miller Taei, a passionate and highlly respected marine conservationist (Ref. 128853).

This species can be distinguished by the following set of characters: cephalic sensory-canal pore system (pattern 1) complete; D/A fin-ray 9/8 formula; pectoral-fin rays 18-20 (usually 19); first 7-10 pectoral-fin rays unbranched, the rest are branched; pelvic-fin ray branches short & connected by membranes ca. midway up branch; 5th pelvic-fin ray 10.6-12.2% of length of 4th ray; absence of spot lateral to pelvic-fin base; no dark spot on mid-caudal peduncle; absence of transverse bars in head and nape; distinct dark spots present on ventral side of head; eye with 4-6 white spokes radiating outwards from pupil & separating red-orange on iris; rectangular blocks on ventral half of body taller than wide and separated from each other by narrow yellow bars less than a pupil diameter; red-orange blotch behind the eye connected to a red-orange spot at back of interorbital region.
Colouration: anal fin darker than other fins, orange scale margins in life, several vertical white lines crossing red-orange region of iris on upper half of eye (Ref. 128853).
Found on outer reef slopes exposed to waves (Ref. 128853).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
