In the last decade, understanding of the Neotropical lizards family Gymnophthalmidae has changed dramatically with the recognition of several new genera, resolution of non-monophyly, definition of previously unknown lineages and refined biogeographic hypotheses. Recent field explorations on the northern Cordillera Central in Colombia uncovered two undescribed species that cannot be assigned to any currently recognized gymnophthalmid genus. Based on a molecular phylogenetic analysis combined with morphological and genetic distances, we describe a new genus and two new species from the northern Andes of Colombia. Magdalenasaura gen. nov. is restricted to the Magdalena biogeographic province and is sister to the cis-Andean genus Gelanesaurus. The new genus can be readily distinguished from all other Cercosaurinae genera by a combination of genetic and morphological characters. The new genus contains Magdalenasaura leurosquama sp. nov. and M. adercum sp. nov., both found in forested habitats near streams at altitudes ranging from 1300 to 1850 m on the eastern flank of the northern Cordillera Central in Colombia. We differentiate the Cercosaurinae genera from Colombia based on general scutellation. Filling the gaps of the tremendous diversity of gymnophthalmid lizards will improve taxonomic and biogeographic hypotheses to better understand the evolution of endemic lineages from the north-western corner of South America. http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4

填补高度多样化的新热带蜥蜴谱系的空白:尾龙亚科(有鳞目:裸眼科)的一个新的地方性属,描述了来自哥伦比亚北部安第斯山脉的两个新物种

在过去的十年中,随着几个新属的识别、非单系的解析、先前未知谱系的定义和完善的生物地理学假设,对新热带蜥蜴科 Gymnophthalmidae 的理​​解发生了巨大变化。最近在哥伦比亚中部山脉北部进行的野外探索发现了两种未描述的物种,它们不能归入任何目前公认的裸眼科动物属。基于结合形态学和遗传距离的分子系统发育分析,我们描述了来自哥伦比亚安第斯山脉北部的一个新属和两个新物种。Magdalenasaura gen。十一月 仅限于马格达莱纳生物地理省,是顺安第斯山属 Gelanesaurus 的姐妹。通过遗传和形态特征的组合,可以很容易地将新属与所有其他尾龙亚科区分开来。新属包含 Magdalenasaura leurosquama sp。十一月 和 M. adercum sp。11 月,它们都发现于哥伦比亚中部山脉北部东侧海拔 1300 至 1850 米的溪流附近的森林栖息地中。我们根据一般的盾形图将尾龙亚科与哥伦比亚区分开来。填补裸眼蜥蜴巨大多样性的空白将改进分类学和生物地理学假设,以更好地了解来自南美洲西北角的地方性谱系的进化。http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4 和 M. adercum sp。11 月,它们都发现于哥伦比亚中央山脉北部东侧海拔 1300 至 1850 米的溪流附近的森林栖息地中。我们根据一般的盾形图将尾龙亚科与哥伦比亚区分开来。填补裸眼蜥蜴巨大多样性的空白将改进分类学和生物地理学假设,以更好地了解来自南美洲西北角的地方性谱系的进化。http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4 和 M. adercum sp。11 月,它们都发现于哥伦比亚中部山脉北部东侧海拔 1300 至 1850 米的溪流附近的森林栖息地中。我们根据一般的盾形图将尾龙亚科与哥伦比亚区分开来。填补裸眼蜥蜴巨大多样性的空白将改进分类学和生物地理学假设,以更好地了解来自南美洲西北角的地方性谱系的进化。http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4 填补裸眼蜥蜴巨大多样性的空白将改进分类学和生物地理学假设,以更好地了解来自南美洲西北角的地方性谱系的进化。http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4 填补裸眼蜥蜴巨大多样性的空白将改进分类学和生物地理学假设,以更好地了解来自南美洲西北角的地方性谱系的进化。http://zoobank.org/urn:lsid:zoobank.org:pub:47E621FD-BEA9-4C65-87D8-D832C4EEC3A4
