Centroscymnus macrops Hu & Li, 1982

[= Centroscymnus coelolepis Barbosa du Bocage & de Brito Capello, 1864 ]

( Figures 5–6 )

Centroscymnus macrops Hu & Li in Chu, Meng, Hu & Li, 1982: 305, fig. 4 (South China Sea).

Centroscymnus macros (misspelling): Compagno, 1984: 56; possibly a synonym of C. coelolepis .

Material examined. SCSFRI O 0150 (holotype), female 792 mm TL, South China Sea, 19°24' N, 114°15.4' E, depth 964 m, 5 Oct 1980 .

Remarks. Described by Hu & Li in Chu et al. (1982) based on a single specimen collected in the South China Sea. Compagno (1984) considered C. macrops to be a possible junior synonym of Centroscymnus coelolepis Barbosa du Bocage & de Brito Capello, 1864 . Examination of the holotype of C. macrops supports the suggestion that it is a junior synonym of C. coelolepis . The smooth, uniform golden brown, leaf-shaped denticles which lack ridges are two of the key characters for distinguishing this species. Hu & Li in Chu et al. (1982) stated that C. macrops differs from C. coelolepis in a shorter snout (less than eye diameter) and shorter preoral distance (subequal to distance from eye to 1 st gill slit. However, these characters do not take into account intraspecific variation and showed that there is no distinct difference in these snout and preoral length ratios when compared with some Australasian specimens (e.g. Figure 7 ). Thus, as previously suggested, C. macrops should be considered a junior synonym of Centroscymnus coelolepis Barbosa du Bocage & de Brito Capello, 1864 .
