Temporal origins of reef fishes in the Indo-Australian Archipelago were examined using wrasses in the genus Macropharyngodon. The genus was selected as it is morphologically and ecologically distinct, with strongly reef-associated species exhibiting discrete distributions across the Indo-Pacific. Phylogenetic relationships were explored using COI, 16S, and 12S rRNA mitochondrial sequences. Monophyly of the genus was supported by congruent Bayesian, maximum likelihood, and maximum parsimony trees. Estimates of lineage ages based on fossil-calibrated reef fish divergences suggest that Macropharyngodon had an extensive evolutionary history starting in the early Miocene. Repeated divergences of Indian Ocean-Pacific Ocean lineages appear to have occurred over at least 19 million years. Regional endemics represent both old and young clades. Our estimates of early Miocene origins, and mid-Miocene to Pliocene diversifications of Macropharyngodon are supported by recent studies of other reef fish genera, and emphasise the importance of pre-Pleistocene events in generating Indo-Pacific coral reef fish biodiversity.
利用咽颌鱼属的濑鱼，研究了印度-澳大利亚群岛珊瑚礁鱼类的时间起源。选择该属是因为其在形态和生态上具有独特性，与珊瑚礁密切相关的物种在印度-太平洋地区呈现出离散分布。利用细胞色素氧化酶亚基I（COI）、16S和12S rRNA线粒体序列探索系统发育关系。贝叶斯树、最大似然树和最大简约树一致支持该属的单系性。基于化石校准的珊瑚礁鱼类分歧对谱系年龄的估计表明，咽颌鱼属从中新世早期开始就有广泛的进化历史。印度洋-太平洋谱系的反复分歧似乎至少发生在1900万年的时间里。区域特有种代表了古老和年轻的分支。我们对咽颌鱼属中新世早期起源以及中新世中期至上新世多样化的估计得到了最近对其他珊瑚礁鱼类属的研究的支持，并强调了更新世前事件在产生印度-太平洋珊瑚礁鱼类生物多样性方面的重要性。
