Etymology: Sovvityazius: Named after the Soviet research vessel 'Vityaz' (abbreviation meaning, Soviet Knight”), type species collected during a survey of this vessel; acer: Name from Latin ‘acer’ meaning sharp sighted, referring to the eyes which are developed better than in other representatives of the subfamily.
Eponymy: ‘Vityaz’ was a famous Soviet research vessel (see Vityaz/Vitiaz). The genus’ name can be taken to mean ‘of the Soviet (vessel) Vityaz’, and the goby type specimens were collected from this ship. (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 26; Anale stekels: 0; Anale zachte stralen: 27; Wervels: 29. This species is distinguished by the following characters: body elongated (H 9.7-11.8 times in SL) but not eel-like; D 40-42 rays; A 38-40; oral fissure almost horizontal, with upper jaw slightly protruded over lower jaw; teeth on premaxillae in one row, uniformly sized, needle-shaped, and densely arranged and with tips slightly inclined posteriorly; teeth on lower jaw is similar, but 0-3 teeth located on each side near symphysis of dentals behind teeth of internal row; head depressed in dorsoventral direction, no sagittal crest, interorbital gap flattened, from 8-10 times in head length; eyes are exceptionally well developed in comparison to other representatives of subfamily, covered by skin, but with normal structure and their vertical diameter only one and half times less than interorbital gap; no barbels or dermal crests on head; P 17-20, symmetrical, with its rays totally connected by membrane and majority of its rays branched; V equal to or longer than P, 60-75% in head length, fully fused into a sucking disc, with rounded posterior
margin, its frenum is narrow but fully developed, without lobules; formula of dorsal pterygiophores 3 1221, a vacant gap between spined and soft parts of D present, two first pterygiophores of soft part of D each in its interneural space and two pterygiophores of A before first hemapophysis, with all pterygiophores having normal structure; pleural ribs from third to tenth centra normally developed, ad parapophyses on posterior precaudal centra weakly developed; vertebrae 10 + 19; absence ot hypural 5 and epurals 2; scales cycloid and well developed; intestine elongated and spirally twisted (Ref. 129446).
