背棘 (總數) : 2; 背的軟條 (總數) : 6 - 7; 臀鰭軟條: 10 - 13; 脊椎骨: 44 - 45. Distinguished from its congeners by a unique combination of the following characters: head length 29.0-32.5% SL, a gently curving snout and a slender, deeply-incised humeral process, and nine vertical columns of black spots on the sides of the body (Ref. 41209).
