Leaf warblers (Aves; Phylloscopidae) are a diverse clade of insectivorous, canopy-dwelling songbirds widespread across the Old World. The taxonomy of Australasian leaf warblers is particularly complex, with multiple species-level divergences between island taxa in the region requiring further scrutiny. We use a combination of morphology, bioacoustics, and analysis of thousands of genome-wide markers to investigate and describe a new species of Phylloscopus leaf warbler from the island of Rote in the Lesser Sundas, Indonesia. We show that this new Rote Leaf Warbler is morphologically and genomically highly distinct from its congenerics, but do not find vocal differentiation between different island taxa. We discuss the behaviour and ecology of this highly distinctive new species, and make recommendations about its conservation status. We believe this constitutes the first description of a novel bird species that is partly based on insights from massive amounts of genome-wide DNA markers.
叶鹎（Aves; Phylloscopidae）是一个广泛分布于旧大陆的、多样化的食虫性、树冠层栖息的鸣禽类群。澳大拉西亚叶鹎的分类特别复杂，该地区岛屿分类群之间存在多个种级分歧，需要进一步仔细研究。我们使用形态学、生物声学以及数千个全基因组标记的分析来研究并描述一种来自印度尼西亚小巽他群岛罗特岛上的新叶鹎物种。我们表明，这种新的罗特叶鹎在形态和基因组上与同属物种高度不同，但在不同岛屿分类群之间没有发现声音分化。我们讨论了这个高度独特的新物种的行为和生态，并对其保护状况提出了建议。我们相信，这是第一个部分基于大量全基因组 DNA 标记的见解来描述的新型鸟类物种。
