家庭水平的慈鲷鱼的分子系统发育分析一般遭受有限的字符和/或穷人的分类抽样在一个或多个主要的地理组合，因此没有提供一个强大的测试早期家族内的多样化。在这里，我们使用核和线粒体的核苷酸特征和直接优化，以重建慈鲷鱼的遗传。其中包括所有地理组合中主要慈鲷谱系的代表，其特征数量几乎是之前任何家族水平研究的两倍。在一个严格的共识，81个同样最吝啬的假设，同时分析2222对齐的核苷酸字符从两个线粒体和两个核基因的基础上，四个主要的亚家族谱系恢复强有力的支持。Etroplinae，马达加斯加特有（Paretroplus）和南亚特有（Etroplus），被恢复为慈鲷科其余部分的姐妹分类群。虽然南亚慈鲷是单系的，但马达加斯加加南亚血统不是。其余的马达加斯加血统，Ptychochrominae，是单系的，并恢复作为姐妹组的一个分支，包括非洲和新热带慈鲷。非洲（Pseudocrenilabrinae）和新热带区（Cichlinae）的谱系在这个重建中都是单系的。使用多个分子标记，从线粒体和核基因，结果在一般表现出强有力的支持，特别是早期的多样化事件慈鲷科内的一个adenogeny。结果进一步表明，Labroidei不是单系的，和姐妹组慈鲷科可能包括一个大的和不同的组合percomorph谱系。这一假说至少可以部分解释为什么形态学研究试图把慈鲷科在Percomorpha，或已测试慈鲷单系只使用“labroid”谱系，只遇到了有限的成功。(c)2004年，威利·亨尼格协会。
Family level molecular phylogenetic analyses of cichlid fishes have generally suffered from a limited number of characters and/or poor taxonomic sampling across one or more major geographic assemblage, and therefore have not provided a robust test of early intrafamilial diversification. Herein we use both nuclear and mitochondrial nucleotide characters and direct optimization to reconstruct a phylogeny for cichlid fishes. Representatives of major cichlid lineages across all geographic assemblages are included, as well as nearly twice the number of characters as any prior family-level study. In a strict consensus of 81 equally most-parsimonious hypotheses, based on the simultaneous analysis of 2222 aligned nucleotide characters from two mitochondrial and two nuclear genes, four major subfamilial lineages are recovered with strong support. Etroplinae, endemic to Madagascar (Paretroplus) and southern Asia (Etroplus), is recovered as the sister taxon to the remainder of Cichlidae. Although the South Asian cichlids are monophyletic, the Malagasy plus South Asian lineages are not. The remaining Malagasy lineage, Ptychochrominae, is monophyletic and is recovered as the sister group to a clade comprising the African and Neotropical cichlids. The African (Pseudocrenilabrinae) and Neotropical (Cichlinae) lineages are each monophyletic in this reconstruction. The use of multiple molecular markers, from both mitochondrial and nuclear genes, results in a phylogeny that in general exhibits strong support, notably for early diversification events within Cichlidae. Results further indicate that Labroidei is not monophyletic, and that the sister group to Cichlidae may comprise a large and diverse assemblage of percomorph lineages. This hypothesis may at least partly explain why morphological studies that have attempted to place Cichlidae within Percomorpha, or that have tested cichlid monophyly using only "labroid" lineages, have met with only limited success.
