我们描述了一种新的 Cornufer 物种，Batrachylodes 亚属，来自东美拉尼西亚俾斯麦群岛新不列颠岛的高海拔森林。新物种 Cornufer exedrus sp。 11 月，是 Batrachylodes 分支的生物地理学分离成员，代表了所罗门群岛以外该亚属的第一个记录。这个新物种是一种小型陆地物种，来自新不列颠东部纳卡奈山脉海拔 1500 米以上的茂密、封闭的树冠森林。它与它的近亲，Batrachylodes亚属的其他成员的不同之处在于其微小的体型、指盘扩张的程度、减少的指下结节、颜色图案以及与其小体型相关的其他特征。我们还提供了新物种简单的广告叫声的描述。尽管最近进行了几项调查，俾斯麦群岛角蜥蜴的多样性很可能仍然被低估。目前，由于缺乏与布干维尔岛特有物种的凭证样本相对应的基因样本和通话记录，我们对 Batrachylodes 亚属的进化趋势和物种边界的理解受到阻碍。
We describe a new species of Cornufer, subgenus Batrachylodes, from high-elevation forests of New Britain Island in the Bismarck Archipelago of Eastern Melanesia. The new species, Cornufer exedrus sp. nov., is a biogeographically disjunct member of the Batrachylodes clade, representing the first record of the subgenus from outside of the Solomon Archipelago. The new species is a small terrestrial form from dense, closed-canopy forests above 1500 meters elevation in the Nakanai Mountains of eastern New Britain. It differs from its closest relatives, the other members of the subgenus Batrachylodes, on the basis of its minute body size, degree of digital disc expansion, reduced subdigital tuberculation, color pattern, and other traits related to its small size. We also provide a description of the new species’ simple advertisement call. The diversity of ceratobatrachid frogs of the Bismarck Archipelago is most likely still underestimated despite several recent surveys. Our understanding of evolutionary trends and species boundaries in the subgenus Batrachylodes currently is hampered by lack of genetic samples and call recordings corresponding to voucher specimens of the endemic species of Bougainville Island.
