| Remarks | Male genital papilla elongate and slender compared to the more robust, rounded papilla of the female; last segmented dorsal and anal-fin rays are more elongate in males, reaching to about the level of the posteriormost procurrent caudal rays, and falling well short of this level in females; filament of upper caudal lobe tends to be much longer in males, frequently damaged in preserved specimens; in females, upper lobe filament is only slightly longer than the lower lobe filament; males exhibit brighter coloration, particularly with regards to the blue stripes on the dorsal fins. |

This species is distinguished by the following characters: D VI + I,11-13 (rarely 13), the spines of first dorsal fin with protruding filaments; A I,10-12 (rarely 12); pectoral-fin rays 18-19; scales in longitudinal series 52-58; total gill rakers on first arch 15-16; segmented caudal-fin rays 17; branched caudal-fin rays 11; forked caudal fin with filament on upper and lower lobe; no preopercular pores; interorbital pores paired; colour in life semi-translucent grey with yellowish hue; with short yellow stripe on snout and from upper eye to pectoral-fin base; blue stripe from mid-interorbital to first dorsal-fin origin; dorsal fins are translucent with yellowish hue, both dorsal fins have prominent basal and submarginal blue stripes; caudal fin yellowish to yellow-brown with blue upper and lower margins (Ref. 105381). |
