型態特徵 | 形態測量圖
背棘 (總數): 9; 背的軟條 (總數): 10; 臀棘 3; 臀鰭軟條: 7. Diagnosis: A species of Gerres with the following combination of characters: body depth 46-47% of standard length, distinctly more than head length; dorsal fin with 9 spines and 10 soft rays; anal fin with 3 spines and 7 soft rays; pored lateral-line scales 43-44; 4-4.5 scales between fifth dorsal-fin spine base and lateral line; 5.5-6.5 scales above lateral line, 9.5-10.5 below; scales on dorsum of head extend to or slightly beyond vertical at front edge of orbit, without two converging rows of minute scales within larger scales, premaxillary groove at front of interorbital area not scaly; gill rakers on first gill arch 12-13; second dorsal-fin spine longest, its length about twice orbit diameter; second anal-fin spine robust, ratio of greatest width of second spine to greatest width of third spine 1.7-1.8; margin of inter-spinous membranes of second to fifth dorsal-fin spines black; caudal fin lobes short, length of upper lobe equal to head length; body with six to eight indistinct dark vertical bars, bar width about half pupil diameter; supraneural bones three (Ref. 75744).
Currently only known from the type locality; no details available on whether habitat is freshwater or brackish (Ref. 75744).
