We describe six new species of the microhylid frog genus Xenorhina from the southern slopes of Papua New Guinea’s central cordillera and adjacent lowlands, based on a combination of morphological (including osteology) and bioacoustic features. All of the new species are fossorial or terrestrial inhabitants of tropical rainforest habitats and belong to a group of Xenorhina having a single, enlarged odontoid spike on each vomeropalatine bone. Advertisement calls and habitat preferences are described for each species, one of which is amongst the smallest hitherto members of the genus. Description of these six species brings the total number of Xenorhina known to 40 and emphasises the importance of the high-rainfall belt that extends along the southern flanks of New Guinea’s central cordillera as a hotspot of Melanesian amphibian diversity.

1863 年来自巴布亚新几内亚南部的 6 个新物种 Xenorhina Peters 的描述（两栖类、无尾类、Microhylidae）

我们根据形态学（包括骨学）和生物声学特征的组合，描述了来自巴布亚新几内亚中部山脉和邻近低地的南坡的六种新种的微型蛙属 Xenorhina。所有新物种都是热带雨林栖息地的化石或陆生居民，属于 Xenorhina 群体，在每个犁腭骨上都有一个单独的扩大的齿状尖刺。描述了每个物种的广告呼唤和栖息地偏好，其中之一是该属迄今为止最小的成员之一。对这六个物种的描述使已知的 Xenorhina 总数达到 40，并强调了沿着新几内亚中部山脉南侧延伸的高降雨带作为美拉尼西亚两栖动物多样性热点的重要性。
