The rough teiid or water cork lizard (Echinosaura horrida) is a small reptile from Colombia and Ecuador placed in a genus that contains eight species and well-known phylogenetic relationships. Here we provide a detailed description and illustrations, bone by bone, of its skull, while we discussed its intraspecific variation by comparing high-resolution computed tomography data from two specimens and the variation within the genus by including previously published data from Echinosaura fischerorum. This allowed to propose putative diagnostic character states for Echinosaura horrida and synapomorphies for Echinosaura. In addition, our discussion includes broader comparisons of new character transformations of the jugal, vomer, orbitosphenoid, and hyoid. These characters are important for diagnosing clades at different levels of the Gymnophthalmoidea phylogeny.
粗鳞鞭尾蜥或水软木蜥（Echinosaura horrida）是一种来自哥伦比亚和厄瓜多尔的小型爬行动物，属于一个包含八个物种且具有知名系统发育关系的属。在此，我们逐骨详细描述并绘制了其头骨，同时通过比较两个标本的高分辨率计算机断层扫描数据讨论了其种内变异，并通过纳入先前发表的费氏棘尾蜥（Echinosaura fischerorum）的数据讨论了该属内的变异。这使得我们能够提出粗鳞鞭尾蜥的假定诊断特征状态以及棘尾蜥属的共衍征。此外，我们的讨论还包括对颧骨、犁骨、眶蝶骨和舌骨新特征转变的更广泛比较。这些特征对于在睑虎超科系统发育的不同水平上诊断分支很重要。
