背鰭 (合計) : 11 - 12; 臀鰭: 9. Differs from its congeners by the following characters: one longitudinal and discontinuous
narrow dark brown stripe running inconspicuously from a vertical through middle of dorsal fin to base of caudal peduncle along lateral line; two or three large dark brown vertically elongated blotches along middle trunk: first at the vertical through dorsal-fin, second anterior to adipose fin and third on the caudal peduncle; mainly in young specimens, 12-13 short transversal dark brown bars meeting small dark brown blotches laterally; snout length 39 to 47.6% in head length; orbital diameter 21.4 to 27.8% of head length; body depth 21.6 to 26.0% of SL; sub-inferior mouth (inferior margin of superior lip horizontally aligned with the inferior margin of infraorbital bones); 4 teeth on each premaxillary and dentary; teeth gross incisive-like, forming
an arched cutting edge, decreasing in size from the symphysal largest pair; 40 to 42 scales in the lateral line, 5,5 or 6 scales series above and 5 under lateral line and 16 circumpeduncular series of scales (Ref. 80692).
Distinct pairs breed on densely grown weedy places (Ref. 205).
