A phylogenetic analysis of the family Lemuridae was accomplished using multiple gene partitions and morphological characters. The results of the study suggest that several nodes in the lemurid phylogeny can be robustly resolved; however, the relationships of the species within the genus Eulemur are problematically nonrobust. The genus Varecia is strongly supported as the basal genus in the family. Hapalemur and Lemur catta are strongly supported as sister taxa and together are the sister group to the genus Eulemur. E. mongoz is the most basal species in the genus Eulemur. E. fulvus subspecies form a monophyletic group with three distinct lineages. E. coronatus is strongly supported as the sister taxon to E. macaco. The relationships of E. rubriventer, E. fulvus, and the E. macaco-E. coronatus pair are unresolved. Our combined molecular and morphological analysis demonstrates the lack of influence that morphology has on the simultaneous analysis tree when these two kinds of data are given equal weight. The effects of several extreme weighting schemes (removal of transitions and of third positions in protein-coding regions) and maximum-likelihood analysis were also explored. We suggest that these other forms of inference add little to resolving the problematic relationships of the species in the genus Eulemur.
利用多个基因分区和形态特征对狐猴科进行了系统发育分析。研究结果表明，狐猴系统发育中的几个节点可以得到有力解决；然而，真狐猴属内物种之间的关系却存在问题，并不稳固。在狐猴科中，维氏冕狐猴属被有力地支持为基部类属。毛耳狐属和环尾狐猴被有力地支持为姐妹分类单元，并且它们共同构成了真狐猴属的姐妹类群。蒙狐猴是真狐猴属中最基部的物种。褐美狐猴亚种形成了一个具有三个不同谱系的单系类群。冠美狐猴被有力地支持为猕猴美狐猴的姐妹分类单元。红腹美狐猴、褐美狐猴以及猕猴美狐猴 - 冠美狐猴这一组之间的关系尚未得到解决。我们的分子和形态学联合分析表明，当这两种数据被赋予同等权重时，形态学对同时分析树的影响并不显著。我们还探讨了几种极端加权方案（去除转换以及蛋白质编码区域中的第三位）和最大似然分析的效果。我们认为，这些其他形式的推断对于解决真狐猴属中物种之间存在问题的关系帮助不大。
