根据最近的分类学重新分类，长臂猿科包含四个属（Hoolock，Nomelae，Symphalangus和Hylobates）和14-18个物种，使其成为迄今为止现存人科中物种最丰富的一组。这些小型树栖灵长类动物被称为“小型猿类”，分布于东南亚、南亚和东亚。现存的长臂猿类的亲缘关系，特别是长臂猿属内的属与种之间的关系，存在着相当大的不确定性。在本文中，我们使用简约，似然，贝叶斯方法来分析一个数据集，包含近14个酶对，其中包括新收集的序列从X-连锁，Y-连锁，和线粒体基因座与以前的线粒体研究的数据。简约，似然，贝叶斯分析在很大程度上没有找到一个显着的差异，与任何四个属的最基本taxon. All分析，但是，支持树与长臂猿和合趾猴最密切相关的属。一个强有力的支持系统发育的结果在长臂猿属是，H。pileatus是最基本的分类群。多重分析未能找到任何单属水平的单发生的显着支持。虽然这是自然的怀疑，可能没有足够的数据系统发育的决议（每当这种情况发生），一个替代假说有关的性质，gibalopsis物种形成存在。这种分辨率的缺乏可能是由于一个快速的辐射或突然的vicariance事件的hylobatid属，它很可能是一个类似的快速辐射发生在Hylobates属。更多的分子和古生物学证据是必要的，以更好地测试这些和其他的假设hylobatid进化。
According to recent taxonomic reclassification, the primate family Hylobatidae contains four genera (Hoolock, Nomascus, Symphalangus, and Hylobates) and between 14-18 species, making it by far the most species-rich group of extant hominoids. Known as the “small apes”, these small arboreal primates are distributed throughout Southeast, South and East Asia. Considerable uncertainty surrounds the phylogeny of extant hylobatids, particularly the relationships among the genera and the species within the Hylobates genus. In this paper we use parsimony, likelihood, and Bayesian methods to analyze a dataset containing nearly 14 kilobase pairs, which includes newly collected sequences from X-linked, Y-linked, and mitochondrial loci together with data from previous mitochondrial studies. Parsimony, likelihood, and Bayesian analyses largely failed to find a significant difference among phylogenies with any of the four genera as the most basal taxon. All analyses, however, support a tree with Hylobates and Symphalangus as most closely related genera. One strongly supported phylogenetic result within the Hylobates genus is that H. pileatus is the most basal taxon. Multiple analyses failed to find significant support for any singlular genus-level phylogeny. While it is natural to suspect that there might not be sufficient data for phylogenetic resolution (whenever that situation occurs), an alternative hypothesis relating to the nature of gibbon speciation exists. This lack of resolution may be the result of a rapid radiation or a sudden vicariance event of the hylobatid genera, and it is likely that a similarly rapid radiation occurred within the Hylobates genus. Additional molecular and paleontological evidence are necessary to better test among these, and other, hypotheses of hylobatid evolution.
