Teleostei (teleosts) > Gobiiformes (Gobies) > Gobiidae (Gobies) > Gobiinae
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.; melanosphena: Name from Latinized Greek 'melanos' for black, and 'sphena' meaning wedge, referring to the dark, wedge-shaped mark at the base of the caudal fin; feminine compound adjective..

Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 8 - 9. This small species (almost always less than 1.3 cm SL; smallest gravid female at 0.095 cm SL) is distinguished from its congeners by the following characters: cephalic sensory-pore lacking only the IT pore ( pattern 2); only some pectoral-fin rays are branched; dorsal/anal fin-ray formula of 9/8; fourth pelvic-fin ray with numerous branches (average 9.6); dark subcutaneous body bars 6, beginning at origin of anal fin; caudal-fin base with a dark, wedge-shaped mark and dark spots bordering upper and lower procurrent caudal-fin rays (Ref. 108793).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 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).
