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.; jewettae: Named for Susan L. Jewett, who previously recognized this species as undescribed from specimens taken by the Smithsonian Philippine Expedition in 1978..

背面の脊椎 (合計) : 6; 背鰭 (合計) : 8; 肛門の骨: 1; 臀鰭: 8. This species is distinguished from congeners by the following set of characters: cephalic sensory-pore system lacking all pores 98% of the time; dorsal/anal fin-ray formula 8/8; pectoral-fin rays 15-16, ventralmost two rays unbranched with at least 2 (but up to 4) lower rays branched at tips above this, remainder of rays unbranched; 4th pelvic-fin ray bifurcated with each branch about 60% of total length of the ray; unbranched 5th pelvic-fin ray 13-20% of 4th; non-filamentous dorsal-fin spines, tubular anterior nares short, less than ½ pupil diameter in length; when alive, body is translucent and crossed by five broad orange to red bands (Ref. 82345).
