多形态属Petaurista包括一组适应滑翔和树栖生活的不同物种和亚种。这种形态上的多样性导致了分类学上的差异，分子系统发育研究受到分类取样的限制。为了澄清这一有争议的分类，我们使用细胞色素B基因重建的系统发育，以获得一个更准确的图片的进化关系，物种分化和分歧模式的Petaurista。结果表明，分类命名，亲缘关系和遗传距离之间的显着不一致。当6个公认的物种，物种界定显示15个推定的物种，一个调查结果，值得全面的形态诊断和重新评估的物种状态。并对犬首拟青霉和海拟青霉的有效性进行了讨论。分子分歧时间的估计表明，Petaurista的多样化和物种形成开始于中新世晚期，可能受到青藏高原隆升和随后的气候变化的影响。
The polymorphic genus Petaurista includes a group of diverse species and subspecies that are adapted for gliding and arboreal life. This morphological diversity has resulted in taxonomic discrepancies, and molecular phylogenetic studies have been limited by taxon sampling. To clarify this controversial taxonomy, we used the cytochrome b gene to reconstruct the phylogeny to obtain a more accurate picture of the evolutionary relationships, species differentiation and divergence pattern of Petaurista. The results revealed a significant inconsistency between taxonomic designations, phylogeny and genetic distances. When 6 recognized species were included, species delimitation revealed 15 putative species, a finding that warrants a comprehensive morphological diagnosis and a re-assessment of the species status. The validity of P. caniceps and P. marica was discussed. An estimation of the molecular divergence time demonstrated that the diversification and speciation of Petaurista began during the later Miocene and may have been affected by the uplifting of the Qinghai-Tibet plateau and subsequent climate change.
