Dorsale stekels (totaal) : 12; Dorsale zachte stralen (totaal) : 10; Anale stekels: 3; Anale zachte stralen: 8; Wervels: 24. This species is distinguished by the following characters: D XII, 10; 14 pectoral fin rays; small orbit diameter (in head length, 3.09-4.09, mean 3.66); blunt snout angle (79°-83°, mean 81°); body prominent pinkish-red with silvery reflection, between each horizontal scale row below lateral line are 5-6 bright cobalt or blue small-spotted lines that are visible only from oblique dorsal view, similar line of small blue spots rising obliquely above lateral line; eye with uniformly reddish-gold sheen; absence of a prominent yellow blotch in the anterior nostril and snout region; dorsal fin rays with saffron-yellow membrane but each ray is reddish-yellow (Ref. 75039).
Most samples were collected by hand-line (Ref. 75039).
