摘要

The Pig-footed Bandicoot, Chaeropus ecaudatus, an extinct arid-adapted bandicoot, was named in 1838 based on a specimen without a tail from the Murray River in New South Wales. Two additional species were later named, C. castanotis and C. occidentalis, which have since been synonymised with C. ecaudatus. Taxonomic research on the genus is rather difficult because of the limited material available for study. Aside from the types of C. castanotis and C. occidentalis housed at the Natural History Museum in London, and the type of C. ecaudatus at the Australian Museum in Sydney, there are fewer than 30 other modern specimens in other collections scattered around the world. Examining skeletal and dental characters for several specimens, and using a combination of traditional morphology, morphometrics, palaeontology and molecular phylogenetics, we have identified two distinct species, C. ecaudatus and C. yirratji sp. nov., with C. ecaudatus having two distinct subspecies, C. e. ecaudatus and C. e. occidentalis. We use palaeontological data to reconstruct the pre-European distribution of the two species, and review the ecological information known about these extinct taxa.

Ecaudatus同义。由于学习可用的有限材料，对该属的分类学研究相当困难。除了在伦敦自然历史博物馆的C. castanotis和C.forcidentalis的类型之外，以及悉尼澳大利亚博物馆的C. eCaudatus的类型，其他收藏的其他现代标本散落在世界各地。检查几种标本的骨骼和牙齿特征，以及使用传统形态学，形态学测量仪，古生物学和分子系统的组合，我们已经确定了两种不同的物种，C. eCaudatus和C. Yirratji SP。 11月。，C. eCaudatus有两个不同的亚种，C. e。 Ecaudatus和C. e。 occidentalis。我们使用古生物数据来重建两种物种的欧洲前分布，并审查了关于这些灭绝的征集所知的生态信息。
