Diagnosis:  Dorsal spines (total): -10; Dorsal soft rays (total): 16-17; Anal spines: -3; Anal soft rays: -8; Vertebrae: -26. This species is distinguished by the following characters: D X, 16-17, the fourth or fifth dorsal spine the longest; anal-fin soft rays 8; pored lateral-line scales 33-34; head 2.3-2.9 in SL; body depth 2.6 in SL. Colouration of males when alive: head and body rose-pink and crossed by 4 bright yellow stripes with the third continuing as a bright red stripe with magenta edges along the middle of the body, becoming yellow centered on base of caudal fin; dorsal fin with a very broad middle yellow stripe, its margin is magenta; anal-fin base colored like body anteriorly and grading broadly to magenta posteriorly; pelvic fins yellow, except the last two rays which is magenta; eye magenta with an uneven ring of yellow around its pupil; immature and presumed female are yellow with irregu¬lar, near-vertical, wavy red lines following scale margins, its anal fin magenta anteriorly, grading posteriorly to purple, with a greenish yellow streak and pelvic fins bright magenta (Ref. 59379).
Biology:  This species was observed and collected along steep limestone coral-reef drop-offs at depths from 115–150 m. The paratypes were collected along a small rocky crevice near the entrance to a cave, but other individuals were seen in similar habitats not in association with caves. Most individuals have been observed in groups consisting of one apparent male and several apparent females and juveniles (Ref. 59379).
