Distribution

The northern Great Barrier Reef and reefs in the Coral Sea, to One Tree Island, Queensland. Elsewhere the species occurs in the tropical, west-central Pacific: Japan (Ryukyu Islands), Papua New Guinea (Trobriand Islands), New Caledonia, Fiji, Tonga, and throughout Micronesia to Kiribati. 
A secretive species found on exposed areas of inshore reefs, including shallow reef flats and wave-swept reef margins.

Dorsal fin VI + I,8-9; Anal fin 1,8-9; Pectoral fin 16-17; Pelvic fin 1,4. Caudal fin branched rays 11-13, segmented rays 17; Lateral scale rows 23-25; Transverse scale rows 6; Vertebrae 10 + 16-17 = 26-27.
Scales absent from breast. Spinous dorsal fin not elongate. Depressed pelvic fin usually not extending to origin of anal-fin origin, never beyond it. Male genital papilla not fimbriate.    

Colour

Pectoral-fin base with large dark orange-brown kidney-shaped to semicircular mark that is darker than trunk bars; head (dorsally) and nape with dark transverse bars, usually complete over dorsal midline, occasionally one or more bars broken up into spots laterally, some with spots or bars darker laterally than dorsally; trunk with prominent, dusky orange, discrete vertical bars, descending to ventral portion of body and continuous over midline; scale pockets on trunk unpigmented.

Etymology

The specific name fasciola is from the Latin fascia (= band) in reference to the bands nearly encircling the trunk.
