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.; bilunula: Name from Latin 'bi' meaning two and 'lunula' for little moon; referring to the two distinctive black crescent-shaped marks underneath the pectoral fin; nominative singular feminine adjective.

Morphology | Morphometrics
soft rays: 7. This species is distinguished by the following characters: cephalic sensory-canal pore system missing only IT pore (pattern 2); dorsal/anal fin-ray formula 7/7 or 8/7; unbranched pectoral-fin rays; 5th pelvic-fin ray 15.9-16.4% of 4th ray; presence of a narrow dark bar at caudal-fin base; with a red line extending down from under eye to jaws; there are 5 postanal ventral-midline spots associated with subcutaneous bars; 2 distinctive black crescent-shaped marks present underneath the pectoral fin (Ref. 113376).
Collected from rubble bottom by clove oil at 13.5 m depth (Ref. 113376).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.2 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
