Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 12 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 8. Rather deep-bodied; head length shorter or equal to body depth; body depth less than 4 times in standard length; ventral fin length less than 1.7 times in head length; eye diameter less than 2.2 times in snout length, less than 2 times in interorbital width; silvery or yellowish.
