The new species is distinguished by having a dorsal\u2010fin origin behind the middle of pectoral fin, a larger head, shorter trunk, larger gill opening, dorsal surface of body with dark\u2010brown colour and ventral surface of head and belly with numerous patches of melanophores before anus, vertebrae 14\u201030\u2010151.
