我们描述了两个新的俄狄皮那属的蝾螈，俄狄皮那亚属，来自厄瓜多尔西北山麓的两个地方，海拔在921和1067米之间。这些是该属最南端的成员。我们检查了不同博物馆的藏品，我们只发现了三个来自厄瓜多尔的俄狄皮纳标本，它们是在该国爬行动物收藏史上获得的。我们确定了三个标本中的两个为新种，但没有确定第三个标本的具体身份，有待进一步研究。Oedipina villamizariorum是该属的一个中等大小的成员，有一个狭窄的，相对尖的头和钝的鼻子；背外侧定向的眼睛，中等大小；手指长度适中，尖尖的。俄狄皮娜，稍大一些，有一个狭窄的头和宽而圆的鼻子；这个新物种不同于所有已知的俄狄皮娜，因为它有成对的额骨和一个简化的指骨公式：0-0-1-0；0-1-2-1-1。我们提供了这两个新物种的骨学的详细描述。最后，基于线粒体DNA的部分序列，我们提出了该属的系统发育假说，包括两个新种中的一个。
We describe two new species of salamanders of the genus Oedipina, subgenus Oedopinola, from two localities on the northwestern foothills of Ecuador, at elevations between 921 and 1,067 m. These are the southernmost members of the genus. We examined different museum collections and we found just three specimens of Oedipina from Ecuador, obtained throughout the history of herpetological collections in the country. We identify two of the three specimens as new species, but refrain from assigning a specific identity to the third, pending further study. Oedipina villamizariorum sp. n. is a medium-sized member of the genus, with a narrow, relatively pointed head and blunt snout; dorsolaterally oriented eyes, moderate in size; and digits that are moderately long and having pointed tips. Oedipina ecuatoriana sp. n., somewhat larger, has a narrow head and broadly rounded snout; this new species differs from all known Oedipina by the distinctive presence of paired prefrontal bones and a reduced phalangeal formula: 0-0-1-0; 0-1-2-1-1. We provide detailed descriptions of the osteology of both new species. Finally, we present a phylogenetic hypothesis for the genus, including one of the two new species, based on partial sequences of mitochondrial DNA.
