We describe a new species of Anolis from the Magdalena river valley in Colombia. The new species is morphologically similar to Anolis ibanezi and A. chocorum, but differs in body and dewlap color, and head scalation. We performed an exploratory multivariate analysis based on 15 morphological characteristics of the new species and A chocorum and found that differences between both species are mainly associated with head dimensions. A phylogenetic analysis based on morphological characters suggests that the new species is nested within the "Dactyloa" clade of Anolis. Finally, we discuss phylogenetic relationships and biogeographical affinities based in its distribution.
我们描述了一种来自哥伦比亚马格达莱纳河谷的新安乐蜥物种。该新物种在形态上与伊氏安乐蜥和乔氏安乐蜥相似，但在身体和喉扇颜色以及头部鳞片方面存在差异。我们基于新物种和乔氏安乐蜥的15个形态特征进行了探索性多变量分析，发现这两个物种之间的差异主要与头部尺寸有关。基于形态特征的系统发育分析表明，新物种嵌套在安乐蜥的“指趾安乐蜥”分支内。最后，我们根据其分布情况讨论了系统发育关系和生物地理亲缘关系。
