Description
Dorsal spines (total): 6-7; Dorsal soft rays (total): 12-13; Anal spines: 1; Anal soft rays: 13; Pectoral fin: 18-19; Segmented caudal rays: 16, middle: 14 branched, upper and lower procurrent caudal rays: 6; Lateral-line scales: 49; Gill rakers: 2+8; Longitudinal scale series: 46-52; Circumpeduncular scales: 11-12; Cycloid body scales; Head without scales except side of nape; Greatest depth of body: 5.8-6.5 in SL: Ovate caudal fin, longer than head length. Prolonged filament formed by third dorsal spine, sometimes more than 50% SL in adult male; United pelvic fins, presence of well developed frenum. Max length: 5.0 cm TL. Depth range: 8 - 20 m.
