摘要通过对模式标本和最近采集的标本的研究发现，Ansonia anotis Inger，Tan，and Yambun，2001和Pedostibes maculatus（Mocquard，1890），这两种都描述于马来西亚的Kinabalu，沙巴，在形态上几乎没有区别。对12 S rRNA、tRNAval和16 S线粒体rRNA基因共2,427 bp的分析显示，这两个物种在遗传上非常接近。因此A. anotis被认为是同种的，并且与P. maculatus同义。在遗传学上，这个物种被证明形成了一个不同于其他来自东南亚的蟾蜍类的谱系，包括Ansonia和Pedostibes的物种。由于该物种也有一些独特的形态特征不同于已知的蟾蜍属，我们建议建立一个新的属Nectophryne maculata Mocquard，1890。
Abstract Examination of types and recently collected specimens revealed that Ansonia anotis Inger, Tan, and Yambun, 2001 and Pedostibes maculatus (Mocquard, 1890), both described from Kinabalu, Sabah, Malaysia, are hardly differentiated morphologically. Analyses of a total of 2,427 bp of the 12S rRNA, tRNAval, and 16S mitochondrial rRNA genes revealed that the two species are very close genetically. Thus A. anotis is regarded as conspecific and is synonymized with P. maculatus. Genetically, this species proved to form a lineage distinct from other bufonids from Southeast Asia, including species of Ansonia and Pedostibes. Because the species has also some unique morphological traits different from known bufonid genera, we propose to establish a new genus for Nectophryne maculata Mocquard, 1890.
