The genus Gephyromantis belongs to the species-rich family Mantellidae and is currently divided in six subgenera. Among these is the subgenus Phylacomantis, which currently includes four described species: Gephyromantis pseudoasper, G. corvus, G. azzurrae, and G. atsingy. The latter three species are distributed in western Madagascar, and two of them (G. azzurrae and G. corvus) occur in the Isalo Massif. Based on the analysis of molecular data (a fragment of the 16S rRNA gene), morphological inspection of museum specimens, and photographic comparisons, G. azzurrae is synonymised with G. corvus and the second Phylacomantis lineage of Isalo is described as G. kintanasp. nov. This medium-sized frog species (adult snout-vent length 35–44 mm) is assigned to this subgenus according to genetic and morphological similarities to the other known species of Phylacomantis. Gephyromantis kintanasp. nov. is known only from the Isalo Massif, while new records for G. corvus extend its range to ca. 200 km off its currently known distribution. These two taxa seem to occur in syntopy in at least one locality in Isalo, and the easiest way to distinguish them is the inspection of the ventral colouration, dark in G. corvus and dirty white in G. kintana.

解决人称蛙类中的分类学和命名学难题：蓝藻Gephyromantis azzurrae与乌鸦座G. corvus的同义词，以及Gephyromantis kintana sp。的描述。十一月 来自马达加斯加西部的Isalo Massif。

Gephyromantis属属于物种丰富的Mantellidae科，目前分为六个亚属。在这些当中，包括了闸门属（Phylacomantis）亚属，该亚科目前包括四个已描述的物种：假单孢子藻（Gephyromantis pseudoasper），克氏葡萄球菌（G. corvus），azzurrae球菌（G. azzurrae）和石棉球菌（G. atsingy）。后三个物种分布在马达加斯加西部，其中两个（G. azzurrae和G. corvus）发生在伊萨洛断层块。基于分子数据分析（16S rRNA基因的一个片段），博物馆标本的形态学检查和照相比较，牛眼G. azzurrae被命名为G. corvus，而伊萨洛的第二个Pylacomantis世系被称为G. kintanasp。十一月 该中型青蛙物种（成人口鼻长度为35-44 mm）根据与其他已知的疫霉属物种的遗传和形态相似性被分配到该亚属。Gephyromantis kintanasp。十一月 仅从Isalo断层块中得知，而有关G. corvus的新记录将其范围扩展到大约。距离目前已知的分布200公里。这两个类群似乎至少在伊萨洛的一个地方是同位的，而区分它们的最简单方法是检查腹侧的颜色，在G. corvus中为深色，在G. kintana中为白色。
