Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 4919)
soft rays: 9. Caudal peduncle and sides behind pectoral fins covered with dark dots; dark lines around eye; sometimes with a dark stripe on midventral line of belly; fins translucent with dark-edged rays; upper and lower edge of caudal fin dark (Ref. 4919).
