簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 14; 背的軟條 (總數) : 13 - 14; 臀棘: 2; 臀鰭軟條: 12; 脊椎骨: 26. This species is distingushed by the following set of characters: differs from C. randalli by having D XIV (vs. XV in C. randalli, the only other congener in the area, and XII-XIII or XV in most other Indo-Pacific species), dorsal-fin rays 13-14 (vs. 10), anal-fin rays II,12 (versus II,10-11), pectoral-fin rays 18-19 (vs. 21-22), principal caudal-fin rays 8-7; spiniform procurrent caudal-fin rays 2; tubed lateral line scales 18 (vs. 21-22); posterior, mid-lateral scales with pore or deep pit 8-9; vertebrae 11 + 15; gill rakers 9-10 + 21-23; total gill rakers 30-32 (vs. 33-37); body moderately deep, depth 1.8-2.0 in SL (vs. 2.3-3.0). Colouration: tail and caudal peduncle yellow; the distal edge of caudal peduncle at junction of posterior dorsal fin with a large white spot, its diameter about width of orbit (Ref. 123146).
Recorded at a depth of 90 m in a rocky patch reef surrounded by a large sandy area; adults were also observed with ROV surveys at Rapa Nui at 90-230 m and Pukao at 150-190 m in rocky patch reefs surrounded by sandy areas, around rhodoliths and fields of whip coral (Stichopathes), along rock walls interspersed with sandy areas, and dead or mostly dead reefs of Leptoseris. Also observed during ROV surveys were juveniles in association with Stichopathes at Pukao at 165 m and Rapa Nui at 150-157 m (Ref. 123146).
