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; cometa: Name from Latin word for comet, referring to the basicaudal spot and the trailing dark streak (Ref. 5291).

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. This species is distinguished from its congeners by the following characters: a cephalic sensory-canal pore pattern lacking only IT pore (pattern 2), AITO pore small and opening dorsally; a dorsal/anal fin-ray formula of 9/8; unbranched pectoral-fin rays 16 or 17 (usually 17); fifth pelvic-fin ray 5-17% of fourth ray; body depth 18-23% SL. Colouration: pectoral-fin base without dark occipital spots or dark spots; entire iris of eye is dark reddish, pupil surrounded by a white ring, dorsal side of eye next to interorbital area has a short white bar not visible laterally; a two-part, black, basicaudal spot over preural centrum made up of a short, wedge-like, triangular front section connecting to a short, wide bar over end of hypural plate, and with a yellow spot over nexus; caudal fin is crossed by thin, red, diagonal bars, pale when preserved (Ref. 127576).
Collected from consolidated coral growth rising 2 m off sand and silt bottom, in 9-15 m depth; also from turbid waters on fine-sand and coral-rubble bottom (Ref. 127576).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

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).
