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 (Nm = 0·02) and genetic differentiation (ϕst = 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.
本研究记录了斜带石斑鱼和褐点石斑鱼之间的主要外部和内部形态差异，并分析了这两个物种的完整线粒体基因组。斜带石斑鱼和褐点石斑鱼之间的部分细胞色素氧化酶亚基 I（COI）序列差异明显高于同一物种内的样本（P<0·05）。基因流动（Nm=0·02）和遗传分化（ϕst=0·92995，P>0·05）的分析表明斜带石斑鱼和褐点石斑鱼之间存在生殖隔离。这些结果支持褐点石斑鱼是一个有效物种的假设。本研究中对斜带石斑鱼和褐点石斑鱼进行的进一步分子比较，以及在 GenBank 中鉴定为韩国斜带石斑鱼的样本，表明后者与褐点石斑鱼相同，而与斜带石斑鱼不同。
