The amphibian fauna of the western Indian ocean volcanic island of Mayotte is currently constituted by two species belonging to two genera of the anuran family Mantellidae: Blommersia transmarina and Boophis nauticus. These were recently described after intense fieldwork on the herpetofauna of the island. We here describe a third new species of frog from Mayotte, based on morphological and molecular data, that occurs in sympatry with the others and was utterly unnoticed until now. Genetic analyses of the16S rRNA gene, including all described and several undescribed species of the genus Blommersia from Madagascar and Mayotte, confirms that the new species is the sister species of Blommersia transmarina. Both species show apparent morphological differences as well as different life histories, ecology and genetics that confirm Blommersia nataliaesp. nov. as a new species. We propose an IUCN Red List status of Critically Endangered for B. nataliaesp. nov.

隐藏在清晰的视线中：科摩罗群岛马约特岛海洋岛上的一种新的蛙属

印度洋西部火山岛马约特岛的两栖动物区系目前由两个物种组成，它们属于无尾类Mantellidae的两个属：Blommersia transmarina和Boophis nauticus。最近在对该岛的Herpetofauna进行了实地考察之后对这些进行了描述。根据形态和分子数据，我们在此描述了来自Mayotte的第三种新青蛙，这种青蛙与其他青蛙共存，直到现在还没有被人注意到。对16S rRNA基因的遗传分析，包括来自马达加斯加和马约特岛的Blommersia属的所有已描述种和几种未描述种，证实了新种是Transloma的Blommersia姊妹种。这两个物种都表现出明显的形态学差异，以及不同的生活史，生态学和遗传学，这些都证实了Blommersia nataliaesp。十一月 作为一个新物种。我们提出了B. nataliaesp严重濒危的IUCN红色名录。十一月
