This species can be well distinguished from congeners by the unique combination of the following features: (1) fins: first dorsal fin rays V; pectoral fin rays 17–20 (modally 18); and first dorsal fin with the longest anterior two rays in male and the fin membrane deeply indented between the first two dorsal spines; (2) squamation: longitudinal scale rows 22–25; transverse scale rows usually 6–7 and predorsal naked; (3) dorsal pterygiophore formulae 3/41001/8; 10 + 16 = 26 vertebrae; (4) head lateral-line system: reduced, longitudinal pattern of infraorbital papilla and anterior oculoscapular canal present (with pore λ singular on middle of interorbital region, pore κ singular on posterior interorbital region and lateral section as pores α, β, and ρ) but lacking both preopercular and posterior oculoscapular canals; and (5) coloration pattern: body creamy yellow with wide longitudinal brown band on ventral half; head with many round brownish black spots; first dorsal fin orange red; pectoral fin orange with an oblique translucent band; second dorsal and caudal fins with several deep brown blotches each having a central black spot.
