背棘 (總數) : 7; 背的軟條 (總數) : 9 - 10; 臀棘: 1; 臀鰭軟條: 8 - 9. This species differs from the other species of the spinosa complex in having the following set of characters: cheek spines 3-6; largest cheek spine slender obviously longer than other spines, length 2.6-6.3% SL; a pupil- or eyesized ovoid black spot on base of caudal fin (extending anteriorly to third mid-lateral scale before posterior margin of hypural); head, body and dorsal fins when alive or fresh has numerous orange speckles; first dorsal fin with no distinct black spot (Ref. 75136); characterized further by having prolonged fourth dorsal spine, forms long filament in adult; longitudinal scale series 22-24; ctenoid predorsal and body scales; cycloid scales in cheek, opercle, pectoral-fin base and prepelvic area; rounded caudal fin; depth of body 3.2-3.7 in SL (Ref. 90102).
Body shape (shape guide): elongated; Cross section: compressed.
Occurs in coral-reef slopes in the protected bays, found solitary on muddy or sandy-mud bottoms with dead-coral rubbles under the heavy growth of corals (Ref. 75136).
