Vertebrae 32(32–33)[32–34] + 15(14–15)[14–15] = 47(47–48)[46–49]. Maximum body depth 5.5(5.3–6.2)[5.6–5.9] times in SL. Caudal peduncle depth 2.0(1.9–2.6)[2.1–2.6] times in its length. Head length 3.8(3.6–4.0)[3.8–4.0] times in SL. Eye diameter 3.8(3.9–5.0)[3.3–4.5] times in head length. Chin barbel shorter than head length, fitting in it 2.8(1.1–2.0)[2.0–2.6] times. Terminal bulb poorly –developed, weakly separable from the stem. Comb-like row of teeth on maxilla hosts 29( 17–23)[ 13–27] slanted teeth, 8(5–6)[5–7] teeth present on pa1atinum, 15(15–16)[15–16] gill teeth present on first gill arch.

Dorsal-fin rays 15(15–16)[15–17], anal-fin rays 13(13–15)[13–15], pectoral-fin rays 8(8)[8]. Length of base of dorsal fin exceeds by III 2.1 (2.0–2.1)[ 1.9–2.2] times that of anal fin. Origin of anal fin below second terminal rays of dorsal fin (below first–third terminal ray of dorsal fin, posterior to vertical J, through its end). Bases of pelvic fins reach vertical through beginning of dorsal fin (not reaching that level, exceeding that level). Dorsal adipose fin originates 7, above 11th (11th–12th) anal-fin ray, ventral adipose fin below 13th (13th–14th) VAV photophore.

Photophores. BR 17(17–18)[17–19]; IP 9(9)[9], PV 13(13–14)[13–14], VAV 18(18–19)[18–19], AC 11(10–12)[10–12], IC 51(51–53)[51–53]; OV 12(11–13)[12–13], VAL 19(19–20)[19–21], OA 32(33)[31–33]. Spaces between photophores five to six times exceed their diameter. Second PV photophore situated above third one of that series. Fifth (fifth and/or sixth) AC photophore slightly elevated in relation to others. Three luminous spots on upper jaw. First spot round and larger than two others, which have elongated shape. Holotype has two small luminous spots posterior to operculum at eye level, paratypes have only precursors of these spots; in specimens designated as additional material, this spot lacking. Short row of luminous spots found between lateral and ventral photophore rows in front of pelvic-fin base: holotype has four such spots on left side and nine spots on right, paratypes have two–ten spots on each side, no such luminous spots found in specimens from additional material. Body color of long preserved specimens light beige 7, (almost white), recently caught specimens have light brown background coloration. Length of largest known specimen 88 mm (SL); sex can be determined in specimens with SL> 79 mm.
