This species is further distinguished by the following: interorbital width narrow, 1.0-1.4 times in horizontal orbit diameter, 5.8-7.5 in HL and 2.0-2.4 in head height at level of middle of eye; eye moderate in size, its diameter 5.2-6.3 times in HL and 2.6-3.0 in snout length; supraorbital outer bony edges of frontals noticeably elevated; snout relatively long, approximately equal to or somewhat shorter than half the head length, 2.1-2.2 in HL; tips of jaws aligned or lower jaw slightly protruding, teeth on symphysis not visible; posterior edge of maxillary extending below 1/3-1/2 of the orbit diameter; a row of rakers on lower part of first gill arch on the outer side of ceratobranchial; pectoral fin extending above to anus or origin of first anal fin ray; first dorsal fin high, 3.3-4.7 times in SL, second and third rays longest; fin membrane of D1 not reaching tips of longest rays, its height about 1.4-1.7 times in height of D1; dorsal fins well separated, posterior edge of D1 fin membrane not reaching first ray base of D2; interdorsal distance wide, 10.9-16.4 times in SL or 1.0-1.9 times in length of D1; bony tuberculation well developed on frontals and lacrimals, D1 flexible spines, branchiostegals, pelvic fins and on bony structures of both lateral lines; absent on maxillary and on anterior part of lower jaw (Ref. 90862).
