This new species differs from the other described species of the genus in the following combination of characters: 10 predorsal scales; second spine of first dorsal fin elongated, filamentous, usually extending beyond base of last segmented ray of second dorsal fin when adpressed; 13-15 pectoral-fin rays; fifth pelvic-fin ray unbranched; cheek fully scaled; transverse lines of cephalic sensory papillae below eye; interorbital shallowly concave with median fleshy ridge, and bony width 90.4-99.0% of pupil diameter; ground color of head and body pale pink, a broad deep pink longitudinal stripe on side of body, and a large dark reddish brown blotch on end of midlateral caudal peduncle when fresh or alive.
