背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀鰭軟條: 12 - 14; 脊椎骨: 52. Distinguished from its congeners by a unique combination of the following characters: head length 30.8-32.4% SL, length of caudal peduncle 15.3-16.1% SL, depth of caudal peduncle 7.8-8.5% SL, dorsal to adipose distance 4.0-7.0% SL, eye diameter 11.5-12.3% HL, 52 vertebrae, and olive green body with orange fins (Ref. 41209).
Body shape (shape guide): elongated; Cross section: compressed.
