摘要

摘要：我们描述了一种来自墨西哥瓦哈卡州华雷斯山脉的Xenosaurus属Knob鳞蜥蜴的新种。尽管该属先前的分子系统发育研究将该新物种确定为一个独特的、未描述的谱系（也是大X.grandis的姐妹分类单元），但我们记录到，它与所有同类的不同之处在于其独特的分级和颜色模式特征组合。该新物种在地理上也与所有同源物种隔离，其地理分布似乎仅限于其典型位置附近，海拔1400米至1800米，位于华雷斯山脉的云雾林带。由于该新物种是一种陆地、生活在裂缝中的物种，通常被人类忽视，地理和生态分布有限，我们计算出其环境脆弱性得分为17，这使其处于环境退化脆弱性高的类别中。

A New Species of Xenosaurus (Squamata: Xenosauridae) from the Sierra de Juárez of Oaxaca, Mexico

Abstract: We describe a new species of Knob-scaled Lizards of the genus Xenosaurus from the Sierra de Juárez of Oaxaca, México. Although this new species was identified as a distinct, undescribed lineage (and sister taxon to X. grandis) by previous molecular phylogenetic studies of the genus, we documented that it also differs from all of its congeners by a unique combination of scalation and color-pattern characters. The new species also is geographically isolated from all congeners and appears to have a geographic distribution limited to the vicinity of its type locality, between 1400 m and 1800 m of elevation, in the cloud forest belt of the Sierra de Juárez. Because the new species is a terrestrial, crevice-dwelling species generally ignored by humans and has a limited geographic and ecological distribution, we calculated its Environmental Vulnerability Score at 17, which places it in the middle of the high category of vulnerability to environmental degradation.
