背棘 (總數) : 7; 背的軟條 (總數) : 27; 臀棘: 1; 臀鰭軟條: 27. This species is distinguished from its congeners by the following set of characters: caudal fin slightly truncate with 17 (9+8) total principal caudal rays, the 5th and 13th branched rays are greatly prolonged as filaments; discontinuous dorsal fin, the interdorsal space about the width of orbit diameter; second dorsal and anal fin are not elevated anteriorly; gill rakers 7+17; no black bar at base of pectoral fin; orange horizontal stripe on posterior body to caudal fin base (Ref. 123270).
This species was collected from the bycatch landings of single day trawlers operated at the
depth of 30-40 m along the Chennai coast at the distance of 20 to 60 km, which stretches from Mahabalipuram in south to Ennore in Northern Tamil Nadu, Bay of Bengal (the area is characterized by natural boulders and coral reefs) (Ref. 123270).
