背棘 (总数) : 0; 背的软条 (总数) : 74 - 85; 臀鳍软条: 61 - 71; 脊椎骨: 60 - 63. Diagnosis: body extremely elongate (depth 9.3-13.3% SL, mean 11.0); 9-12 rakers on first gill arch (Ref. 81644). Head rounded in dorsal outline (Ref. 248), rather short (HL 18.3-22.8% SL, mean 20.2) and wide (width 14.1-17.0% SL, mean 15.4)(Ref. 81644). Snout broadly rounded (Ref. 248). Eyes small and laterally placed (Ref. 248). Interorbital width large (45.4-50.7% HL, mean 47.7)(Ref. 81644). Postorbital margin not entirely covered with bone; frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped; supra-orbital and "dermosphenotic" bones separated; tooth plates relatively broad; pectoral spine straight (Ref. 248). Pectoral spine slightly serrate on its anterior face, with serrations downward oriented (Ref. 248, 81644). Gill rakers relatively long and distantly set; suprabranchial organ well developed (Ref. 248). Openings of secondary sensory canals show a regular pattern (Ref. 248, 81644).
Coloration: preserved specimens with uniform colouration; back, flanks and upper parts of paired fins dark brown to reddish brown; ventrum and lower parts of paired fins pale brown to beige (Ref. 81644).
