This study documents the major external and internal morphological differences between Epinephelus bruneus and Epinephelus moara , and analyses the complete mitogenomes of both species. The partial cytochrome oxidase subunit I ( coI ) sequence divergence between E. bruneus and E. moara is significantly higher than specimens within the same species ( P < 0·05). Analyses of gene flow ( N m = 0·02) and genetic differentiation (ϕ st = 0·92995, P > 0·05) reveal reproductive isolation between E. bruneus and E. moara . These results support the hypothesis that E. moara is a valid species. Further molecular comparisons between E. bruneus and E. moara obtained in this study and a specimen identified in GenBank as E. bruneus from South Korea reveal that the latter is identical to E. moara rather than to E. bruneus .
