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.

背棘 (总数) : 7; 背的软条 (总数) : 9 - 10; 臀棘: 1; 臀鳍软条: 8 - 9. This species possess the following characters: D VI-I,9-10; A I,8-9; pectoral rays 17-19, pectoral rays 10-19 may be branched, 13-17 always branched except smallest paratype without branched rays; pelvic rays 1,4 1/10 (6) or 1.4 2/10 (1), fourth ray with 6-10 primary branches, averaging 8; with 1 or sometimes 2 segments between consecutive branches of the fourth pelvic-fin ray; well developed pelvic-fin membrane; branched caudal-fin rays 11-13, or 1 damaged; segmented caudal-fin rays 17; lateral scale rows 24 or 25; transverse scale rows 7 or 8; breast naked; naked area of forehead extending posteriorly in a narrow strip along base of dorsal fin. The cephalic pore system conforms with pattern 1 of Lachner and Karnella (1980); very small anterior interorbital pore (AITO); cutaneous papilla system conforms with pattern A of Lachner and Karnella (1980). The first dorsal spine is variable in length, often elongate in adults, extending as far as the caudal peduncle in some individuals, this elongate first dorsal filament is easily damaged and missing in the holotype and some paratypes. Male genital papilla not fimbriate, flattened and relatively elongate with fringe of tiny papillae along distal edge, its maximum length extending slightly beyond origin of anal fin; female papilla short, bulbous, with several finger-like projections, extending to anal spine (Ref. 81726). Dorsal to anal fin-ray formula 9/8 (Ref. 116739).
Body shape (shape guide): elongated; Cross section: oval.
