在这里，多位点序列数据与现场着色观察相结合，以识别一个新物种，来自印度洋和红海珊瑚三角的Eviota punyit。宽松的分子钟发散时间估计表明新物种的起源是上新世，而新物种及其姊妹物种Eviota sebreei的当前分布支持跨越印度太平洋屏障的情景，随后范围扩大并在珊瑚三角重叠。这些结果与“重叠中心”假说是一致的，该假说认为珊瑚三角的多样性增加部分是由于印度洋和太平洋动物的重叠范围。这些发现是在其他由印度洋-太平洋屏障隔开的成对珊瑚礁鱼类的背景下讨论的。(C) 2016年不列颠群岛渔业协会
Here, multi-locus sequence data are coupled with observations of live colouration to recognize a new species, Eviota punyit from the Coral Triangle, Indian Ocean and Red Sea. Relaxed molecular clock divergence time estimation indicates a Pliocene origin for the new species, and the current distribution of the new species and its sister species Eviota sebreei supports a scenario of vicariance across the Indo-Pacific Barrier, followed by subsequent range expansion and overlap in the Coral Triangle. These results are consistent with the 'centre of overlap' hypothesis, which states that the increased diversity in the Coral Triangle is due in part to the overlapping ranges of Indian Ocean and Pacific Ocean faunas. These findings are discussed in the context of other geminate pairs of coral reef fishes separated by the Indo-Pacific Barrier. (C) 2016 The Fisheries Society of the British Isles
