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.; disrupta: disrupta meaning broken up, in reference to the pattern of the vertical trunk bars (Ref. 5289). More on authors: Karnella & Lachner.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal. Tropical
Central Pacific: Fiji, Samoa and Tonga Islands to Mangaréva (French Polynesia).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 1.6 cm SL male/unsexed; (Ref. 5289)
soft rays: 7 - 8;
Vertebrae: 26. Characterized by the following: base of pectoral fin with two sharply defined, circular dark spots, clearly separated, of about equal size; pectoral spots intensely pigmented, more so than trunk bars; head (dorsally) and nape with large dark spots, usually arranged transversely and discontinuous along dorsal midline; trunk with dark, discretely outlined, vertical bars, some of which are almost always irregularly broken into elongate, oval or oblong shaped marks on the anterolateral portion of the body; trunk bars extending ventrally below midside of body and often discontinuous over midline on anterior part of trunk; scale pockets on trunk not pigmented (Ref. 5289). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00891 (0.00421 - 0.01885), b=3.07 (2.89 - 3.25), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
