拥有近1，100个物种，科鱼类占了一半以上的Characiformes物种，是新热带淡水生态系统的关键组成部分。尽管在形态学和分子数据分析的基础上做出了重大努力，但目前尚不确定该科的组成、发生和分类。关于这一群体的单系性或其在Characiformes中的位置尚未达成共识，许多关键研究迄今为止都没有重叠的分类表示，并且只关注这种多样性的子集。在本研究中，我们提出了一个新的定义的家庭？科？和一个假设的关系？Characiformes基于系统发育分析的DNA序列的两个线粒体和三个核基因（4,680碱基对）。这些序列来自211个样本，代表166个属，分布在所有18个公认的科中的Characiformes，所有14个公认的亚科，加上56个属，到目前为止，认为incertae sedis在科。所获得的遗传学是强大的，与大多数血统显着支持贝叶斯分析中的后验概率，并从最大似然和简约分析的高自举值。在我们所有的系统发育分析中得到有力支持的一个单系组合在此被定义为科，包括缺乏眶上骨和舌骨动脉从前角舌骨出现的衍生位置的字符形物种。为了认识到这一点和其他几个单系群内characiforms，我们建议的几个家庭的限制，以促进未来的研究Characiformes，特别是鱼科的变化。这项工作提出了一个新的系统发育框架的一个物种和形态多样的淡水鱼类的重要生态和进化的重要性，在整个新热带和非洲的部分地区。
With nearly 1,100 species, the fish family Characidae represents more than half of the species of Characiformes, and is a key component of Neotropical freshwater ecosystems. The composition, phylogeny, and classification of Characidae is currently uncertain, despite significant efforts based on analysis of morphological and molecular data. No consensus about the monophyly of this group or its position within the order Characiformes has been reached, challenged by the fact that many key studies to date have non-overlapping taxonomic representation and focus only on subsets of this diversity. In the present study we propose a new definition of the family Characidae and a hypothesis of relationships for the Characiformes based on phylogenetic analysis of DNA sequences of two mitochondrial and three nuclear genes (4,680 base pairs). The sequences were obtained from 211 samples representing 166 genera distributed among all 18 recognized families in the order Characiformes, all 14 recognized subfamilies in the Characidae, plus 56 of the genera so far considered incertae sedis in the Characidae. The phylogeny obtained is robust, with most lineages significantly supported by posterior probabilities in Bayesian analysis, and high bootstrap values from maximum likelihood and parsimony analyses. A monophyletic assemblage strongly supported in all our phylogenetic analysis is herein defined as the Characidae and includes the characiform species lacking a supraorbital bone and with a derived position of the emergence of the hyoid artery from the anterior ceratohyal. To recognize this and several other monophyletic groups within characiforms we propose changes in the limits of several families to facilitate future studies in the Characiformes and particularly the Characidae. This work presents a new phylogenetic framework for a speciose and morphologically diverse group of freshwater fishes of significant ecological and evolutionary importance across the Neotropics and portions of Africa.
