Head high, not flattened as in G. viridis, so its height (8.0-8.9% L) is 

 greater than its width. Cheeks muscular but not expanded; almost vertical. Head 

 length measured to posterior edge of gill membrane 15.5-16.4% L (to end of oper- 

 cle 14.6-15.0% L). Eye small, equal snout, its diameter 3,3% L, 20.0-21.2% head. 

 Eyes placed high on head, close to each other, interorbital 3.5-4.4% head. Upper 

 jaw reaching to vertical from posterior end of eye. Its length 6.5-6.6% L, 40.0- 

 42.3% head. Upper lip structure characteristic; on sides high and free, anteriorly, 

 at tip of snout (slightly lower) adnate . Lower lip free, slightly widened anteriorly, 

 but attached narrowly at tip of lower jaw. Length of free part 2-1/2-3 m eye. 

 palatine membrane well developed as in all forms close to Gymnelis ( Gymnelopsis 

 Soldatov, Derjuginis Popov, Commandorella Taranetz & Andriashev, etc.). Small 

 noticeable pores on lower jaw, edge of preoperculum and around eye. Interorbital 

 without pores . Strong coniceil teeth on jaws, vomer and palatines . Gill opening 

 extends to level of middle of pectoral base . 



Body naked, its depth at anal base 8.9-9.2% L. Origin of dorsal over 

 anterior 1/4 of pectoral. Predorsal small, 16.1-17.9% L, preanal 35.7-38.0% L. 

 Unpaired fins high, length of longest dorsal ray twice diameter of eye . Anal 

 with a serrated edge, its height slightly more than eye. Pectoral 8.9-10.0% L. 

 57.5-64.6% of head. Lateral line mediolateral, indistinct. 



Colors (in life): Body light, yellowish with 809 broad rings, marbled pattern 

 of reddish brown. Same pattern on dorsal. Anal and pectoral light. Two small 

 spots with a marbled pattern on head . Posterior one on nape, separated from 

 anterior by a light curved (anteriorly) line. The front spot originates by a 

 narrow line through the lower and upper lips, broadening and continuing on 

 operculum where it is connected to spot on nape. One example differs in color- 

 ation; having wide brown bars without marbled pattern but instead irregular small 

 and large light, dark edged spots . Dorsal with three black ocelli .
