我们描述了来自马达加斯加中北部东海岸的两种新的半树栖青蛙物种，它们普遍存在于诺西博拉哈岛上。这两个物种在形态上最接近 Blommersia wittei，但在广告叫声和分子系统发育关系上有所不同。其中一种新物种具有显着的股骨腺结构，因为它们向大腿远端移动，靠近膝关节。这种新物种显然是马达加斯加东海岸一小片地区的小地方病，迄今为止尚未在更高海拔地区发现。由于这两个新物种都能耐受栖息地干扰，并且出现在人工改变的栖息地，例如种植园和村庄，因此我们建议将其列为 IUCN 的“最不关注”威胁状态，尽管它们的出现范围有限。
We describe two new species of semiarboreal frogs from the northern central east coast of Madagascar which occur syntopically, at least on the island of Nosy Boraha. The two species are morphologically closest to Blommersia wittei, but differ in advertisement calls and molecular phylogenetic relationships. One of the new species has a remarkable femoral gland structure, as these are shifted towards the distal part of the thigh, close to the knee joint. The new species are apparently microendemic to a small stretch of Madagascar's east coast and have so far not been found at higher elevations. Since both new species are tolerant of habitat disturbance and occur in anthropogenically altered habitats, such as plantations and villages, we propose an IUCN threat status of Least Concern despite their restricted extent of occurrence.
