Dorsal soft rays (total): 6; Anal soft rays: 17 - 18; Vertebrae: 28 - 29. This species is distinguished from its congeners by the following set of characters: dorsal-fin rays 6 (6 seen in holotype); anal-fin rays modally 17; pelvic-fin rays 6 (6); pectoral fin rays 9-10; body compressed laterally, robust anteriorly and slender posteriorly; body depth at pelvic origin 20.9-23.3 (22.3); body depth at anal fin origin 17.2-20.1 (18.8); the dorsal-fin origin inserted almost at the vertical of 12th anal-fin rays; membrane between dorsal-fin 5th and 6th rays with distinct notch in adult male; body translucent, light creamy yellowish to light brown, a conspicuous, narrowly dotted, longitudinal black line along the middle forward to vertical above pelvic fin; belly wall, peritoneum slivery, somewhat subrectangular; operculum and pre-pectoral region slivery; absence silvery scales on lateral body except central part of middle body; eye light bluish silvery dorsally; all fins and belly translucent and colored pale white; caudal fin unmarked; and pelvic and anal fin with widely scattered tiny melanophores (Ref. 138528).
Body shape (shape guide): elongated; Cross section: compressed.
