MATERIAL EXAMINED (5 spec.).— SCS: ASIZP 65559 (1, 170+ TL) ; CD 136, 998– 1211 m; ASIZP 66095 (1, 270+ TL) ; CD 324, 1293 m. SWT: ASIZP 65620 (1, 331 TL) ; CD 228, 1262–1290 m. SET: ASIZP 67020 (1, 310+ TL, 61 HL) ; CP 353, 1205 m. Other material: ASIZP 68059 (1, 390 TL) ; Aurora, the Philippines .

DISTINGUISHING FEATURES.— A species of Cetonurus with large orbit (24–28% HL); small scales (18–19 rows below 1D and 14–16 rows below 2D); and 3–4 rows of closely spaced teeth on premaxilla. Size to 510 mm TL.

DISTRIBUTION.— This species is widespread in tropical and subtropical waters of the Indo-West Pacific and Atlantic but is absent in the central and e. Pacific. In the w. Pacific it is found off Japan, Taiwan, New Zealand, and Australia. Four specimens were collected in the South China Sea and the s. coast of Taiwan at depths between 998 and 1293 m.

REMARKS.— The only congener, C. crassiceps ( Günther, 1878) , is a closely similar species that has been recorded from the Kermadecs, Hawaiian Islands, Vanuatu, Loyalty Ridge, Norfolk Ridge, Lord Howe Rise, and in the central and South Atlantic. Characters used by Sazonov and Shcherbachev (1985) to distinguish the only two members of the genus are weak and need to be further tested. Three of the specimens here listed were the basis for Shao et al.’s (2008:fig. 2) first record of the species from Taiwan.
