Phylogenetic relationships among angelfishes (Pomacanthidae) and their putative sister taxon, the butterflyfishes (Chaetodontidae), were examined using 12S and 16S mitochondrial DNA sequences. ML and MP trees were highly congruent with good basal resolution. Monophyly of the two families was supported, although a clade comprising the Chaetodontidae and one of the outgroups, the Scatophagidae, formed the sister clade to the Pomacanthidae. All genera and subgenera within the Pomacanthidae were examined. The relationships among the 24 representative species were consistent with traditional generic boundaries, with the exception of the genus Centropyge, but differed from previous phylogenies. Estimated ages of divergence based on trans-isthmian pairs were compared with independent fossil evidence. Trans-isthmian estimates were highly conservative, while fossil-calibrated estimates were most consistent with available evidence. Fossil calibrated estimates suggest that the family has been impacted by both the Terminal Tethyan Event and the closure of the Isthmus of Panama. Within the family, ecological diversity and species-level diversification are restricted primarily to a single pygmy angelfish clade with an origin near the Oligocene-Miocene boundary.
利用12S和16S线粒体DNA序列研究了神仙鱼（棘蝶鱼科）及其假定的姐妹分类单元蝴蝶鱼（蝴蝶鱼科）之间的系统发育关系。最大似然法（ML）树和最大简约法（MP）树高度一致，基部分辨率良好。支持这两个科的单系性，尽管一个包含蝴蝶鱼科和一个外类群（金钱鱼科）的分支形成了棘蝶鱼科的姐妹分支。对棘蝶鱼科内的所有属和亚属进行了研究。24个代表性物种之间的关系与传统的属界一致，但刺尻鱼属除外，不过与之前的系统发育不同。将基于地峡两侧物种对的分歧估计年龄与独立的化石证据进行了比较。地峡两侧的估计非常保守，而化石校准的估计与现有证据最为一致。化石校准的估计表明，该科受到了特提斯晚期事件和巴拿马地峡关闭的影响。在该科内，生态多样性和物种水平的多样化主要局限于一个起源于渐新世 - 中新世边界附近的单侏儒神仙鱼分支。
