Description
Dorsal fin: XIII, 12-14 (usually 13); Anal fin: II, 12–14 (usually 13); Pectoral fin: 16–18 (usually 17); Gill rakers on first branchial arch: 4–6 + 11–13, total rakers: 16–19 (usually 17–18); Lateral-line scales (tubed): 16–18 (usually 17). Max length: 5.0 cm SL. Depth range: 1 - 8 m.
Color
Generally pale yellow to whitish with blue (young fish) or dark blue-grey (adult fish) region encompassing snout, upper head and adjacent anterodorsal portion of body and spinous dorsal fin; small blackish spot at uppermost rear edge of operculum near origin of lateral line; each scale of suborbital, preopercle, and opercle with small blue spot; each body scale with 1–2 small blue spots, generally darker on anterior half of body; young fish with scattered neon blue spots on dark blue forehead and snout; fins (except dark blue or greyish spinous dorsal) semitranslucent with pale yellow to whitish hue except for pair of submarginal blue stripes on spinous dorsal fin.
Etymology
Chrysiptera: from Greek, chrysos = golden + from Greek, pteron = fin, wing.
caesifrons: from Latin, caesius = blue-grey + from Latin, frons = forehead or brow. In reference to its distinguishing colour pattern. The specific name means "bluish-grey forehead”.
Original description: Chrysiptera caesifrons Allen, Erdmann & Kurniasih, 2015 - Type locality: Ayau Kecil Island, Ayau Atoll, Raja Ampat Islands, West Papua Province, Indonesia, 1.5–2.0 m.
Distribution
The new species is primarily restricted to the southwestern Pacific Ocean with confirmed records from Halmahera and West Papua, Indonesia, northeastern Papua New Guinea (including New Britain, Admiralty Islands, and Milne Bay Province), Solomon Islands, Vanuatu, New Caledonia, and Australia. Australian localities include the entire extent of the Great Barrier Reef.
Biology
The habitat consists of rocky substrates, frequently close to shore, often in gullies just below the surge zone at depths of about 1–6 m. It generally occurs solitarily or in small, loose groups.
