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; kathyae: Name 'kathyae' in honor of Kathryn (Kathy) Uhrig Kimball, the second author’s life companion and an active diving member of the expedition that uncovered this beautiful new species.

Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 7. This species is distinguished from its congeners by the following set of characters: unbranched pectoral fin rays; a cephalic sensory-canal pore system lacking only the IT pore; a dorsal/anal-fin formula of 8/7; absence of fifth pelvic-fin ray; a black blotch at caudal-fin base; absence of prominent lines crossing caudal fin; and iris above pupil crossed by an unbroken red bar (Ref. 138731).
Body shape (shape guide): elongated; Cross section: oval.

Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00692 (0.00283 - 0.01691), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-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.). |
