Distinguished from all congeners known to date by the combination of the following

characters: adult males with basically truncate transparent caudal fin without markings, both lobes with filamentous streamers in largest specimens; first membranes of dorsal fin pointed and prolonged to nearly double length of spine, creating serrated impression; pectoral fin base whitish to ivory without any dark markings in all specimens examined, creating distinct contrast with overall yellowish-brown body; broad lateral band on L+1-scale row, ending on upper third of caudal peduncle at vertical bar 7, separated from rectangular spot on centre of caudal base, centre of spot light brown creating impression of divided spot; two to three fragmentary rows of distinct oval abdominal spots, more intense in caudalmost part

above anal fin; gill cover significantly darker than rest of body below lateral band; distinct preorbital, postorbital, and cheek stripes; no black markings on ventral surface of head or body apart from short narrow grey pre-anal stripe, occasionally visible in very large specimens only (Ref. 94125).
