We describe a new plethodontid salamander species of the genus Isthmura, known only from one locality in the mountainous region of central Veracruz, Mexico. Like its congeners, Isthmura corrugata sp. nov. has a large and robust body, but it is easily distinguished from the other species in the genus by the absence of any spot or mark on the dorsum (except by dull reddish brown coloration on eyelids) and by extremely well-marked costal grooves separated by very pronounced costal folds. Based on an mtDNA phylogeny, the new species is most closely related to the geographically distant I. boneti and I. maxima but occurs very near I. naucampatepetl and I. gigantea on the eastern slope of Cofre de Perote, Veracruz. The region where I. corrugata occurs contains a high number of plethodontid salamander species and is threatened by human activity.
我们描述了一种新的地栖蝾螈属（Isthmura）物种，仅在墨西哥韦拉克鲁斯中部山区的一个地点被发现。与同属其他物种一样，皱纹地栖蝾螈（Isthmura corrugata sp. nov.）体型大且粗壮，但它很容易与该属其他物种区分开来，其背部没有任何斑点或斑纹（除了眼睑上暗淡的红棕色），且肋沟非常明显，由非常突出的肋褶隔开。基于线粒体DNA系统发育分析，新物种与地理上相距遥远的博内蒂地栖蝾螈（I. boneti）和大形地栖蝾螈（I. maxima）关系最为密切，但在韦拉克鲁斯佩罗特火山（Cofre de Perote）东坡，它与瑙坎帕泰佩特尔地栖蝾螈（I. naucampatepetl）和巨型地栖蝾螈（I. gigantea）的分布区域非常接近。皱纹地栖蝾螈的分布区域有大量的地栖蝾螈物种，且受到人类活动的威胁。
