Abstract：
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.
摘要：
粗糙的teiid或水软木蜥蜴（Echinosaurahorida）是一种来自哥伦比亚和厄瓜多尔的小型爬行动物，属于一个属，包含八个物种和众所周知的系统发育关系。在这里，我们提供了详细的描述和插图，逐个骨头，它的头骨，虽然我们通过比较来自两个标本的高分辨率计算机断层扫描数据来讨论其种内变异，并且通过包括先前发表的来自Echinosaurafischerorum的数据来讨论该属内变异。这允许为棘皮草提出假定的诊断性态，并为棘皮草提出突触状态。此外,我们的讨论包括更广泛地比较jugal的新角色转换，vomer,眶蝶骨,还有舌骨.这些特征对于诊断不同水平的裸眼系统发育的进化枝很重要。
