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.; bipunctata: Name from Latin 'bi' for two and 'punctum' meaning dot or spot, referring to the 2 dark spots on the fleshy pectoral-fin base.

soft rays: 7 - 9;
Vertebrae: 26. This species is distinguished from its congeners by the following characters: cephalic sensory-pore system lacking only the IT pore (pattern 2); only some pectoral-fin rays are branched; pectoral-fin base have 1 or 2 prominent dark spots; dorsal/anal-fin formula usually 8/8; without occipital spots (Ref. 108789).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (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
): 3.0 ±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
): Low vulnerability (10 of 100) .
