Data from: Multilocus phylogeny and a new classification for Southeast Asian and Melanesian forest frogs (family Ceratobatrachidae)

We present a near comprehensive, densely sampled, multilocus phylogenetic estimate of species relationships within the anuran family Ceratobatrachidae, a morphologically and ecologically diverse group of frogs from the island archipelagos of Southeast Asia and the South-West Pacific. Ceratobatrachid frogs consist of three clades: a small clade of enigmatic, primarily high-elevation, semi-aquatic Sundaland species currently assigned to Ingerana (for which we erect a new genus), which is the sister taxon of two large, monophyletic radiations, each situated on islands on either side of Wallace's Line. One radiation is composed of Philippine species of Platymantis and the other contains all taxa from the eastern Indonesian, New Guinean, Solomon, Bismarck, and Fijian archipelagos. Several additional genera (Batrachylodes, Discodeles, Ceratobatrachus, and Palmatorappia) are nested within Platymantis, and of these Batrachylodes and Discodeles are nonmonophyletic. To address the widespread paraphyly of the genus Platymantis and several additional nomenclatural issues, we undertook a wholesale nomenclatural reorganization of the family. Given our partially unresolved phylogeny, and in order to impart a conservative, stable taxonomy, involving a minimal number of genus-species couplet changes, we propose a conservative classification representing a few compromises. These changes are designed to preserve maximally the presumed original intent of taxonomy (widely used group names associated with morphological and ecological diversity of particular species or groups of species) while implementing a hierarchical system that is consistent with the estimate of phylogeny based on new molecular data.

本研究针对无尾目尖吻蛙科（Ceratobatrachidae）的物种亲缘关系，基于多基因座高密度采样数据构建了近乎全面的系统发育估算结果；该科是分布于东南亚及西南太平洋岛群的一类形态与生态特征均具高度多样性的蛙类类群。尖吻蛙科类群包含三个演化支：其一为一小支具神秘演化地位的类群，该支物种多栖息于高地、营半水生生活，现归类于英格蛙属（Ingerana），我们将为其建立一新属；该小支是两大单系辐射演化支的姊妹群，这两大辐射演化支分别分布于华莱士线（Wallace's Line）两侧的岛屿之上。其中一支辐射类群由菲律宾的扁手蛙属（Platymantis）物种构成，另一支则涵盖了印尼东部、新几内亚、所罗门群岛、俾斯麦群岛以及斐济群岛的所有分类群。另有四个属（Batrachylodes、Discodeles、Ceratobatrachus及Palmatorappia）嵌套于扁手蛙属之内，其中Batrachylodes与Discodeles为多系群。为解决扁手蛙属普遍存在的并系问题以及其他多项分类命名争议，本研究对该科开展了全面的分类命名重整工作。考虑到本研究的系统发育树仍存在部分未解析的节点，且为构建一套保守且稳定的分类系统，同时尽可能减少属种组合的调整次数，我们提出了一套兼顾多方妥协的保守分类方案。该分类调整方案旨在最大程度保留分类学的原有核心宗旨——即沿用与特定物种或物种类群的形态、生态多样性相关的通用类群名称，同时构建一套与新分子数据所得的系统发育估算结果相一致的层级分类体系。
