摘要对中国6种肌炎物种的细胞色素-b基因进行了测序，将它们的分子系统学加入到旧大陆肌炎物种的分子系统发育研究中，并明确了这些东亚物种的系统发育地位。结果表明，大多数东半球的Myotis可分为6个支系，即支i -支VII和埃塞俄比亚支系。本文所提到的“daubentonii”种，如Myotis capaccinii、M. daubentonii、M. longipes、M. fimbriatus和M. macrodactylus，均存在差异，说明可疑种M. longipes和M. fimbriatus均为有效种，支持“daubentonii”类群的形态和行为相似性是趋同进化的结果。与异域种M. ikonnikovi和M. mystacinus形成一个单系类群，表明它们的形态差异可能是由生态环境差异引起的。该分支包括M. davdii、M. siligorensis、M. longipes以及两个未确定的M. sp1和M. sp2。
Abstract We recently sequenced the cytochrome-b gene of six Chinese Myotis species, added their molecular systematics into the previous molecular phylogenetic studies on the Old World Myotis, and clarified the phylogenetic status of these East Asian species. The results demonstrate that most Old World Myotis are divided into six clades, namely Clade I–Clade VII and the Ethiopian Clade. All the “daubentonii” species referred to here, such as Myotis capaccinii, M. daubentonii, M. longipes, M. fimbriatus, and M. macrodactylus, are divergent from each other, indicating that the questionable species M. longipes and M. fimbriatus are valid species, and supports that the morphological and behavioral resemblance in the “daubentonii” group are caused by convergent evolution. Myotis altarium forms a monophyletic group with two allopatric species M. ikonnikovi and M. mystacinus, suggesting that their morphological differences might have been caused by their eco-environmental differences. Our data also imply the abundance of species diversity in a certain clade, which consists of M. davidii, M. siligorensis, M. longipes, and two unidentified species M. sp1 and M. sp2.
