Short Description
A relatively large species with the following characters: tall dorsal fins, its posterior margin directed posteroventrally from top to bottom and not upright distally, first dorsal-fin base is 1.6-2.0 times the anal-caudal space; buccopharyngeal denticles cover entire palate and floor of mouth; long claspers of adult males are slender, strongly depressed, the inner length about 9-10% TL, extending to just anterior of the second dorsal-fin origin; lower edge of spiracle is usually close to level of mid-eye; insertion of anal-fin usually over its apex; about 69/73 teeth rows; 78- 94 precaudal vertebral centra; 35-39 monospondylous centra; dorsal color pale greyish with numerous small, often indistinct, semi-regular, diffuse-edged white spots on postspiracular head and body; light and dark tonal coloration well demarcated on head below eye and onto middle of first gill slit, the intergill membranes are much darker dorsally than ventrally; bases and inner lobe of dorsal fins in juveniles (
