尽管 Tropicoperdix 被认为是雉科树鹧鸪属（山鹧鸪）中的一个完整属或一个物种复合体，但长期以来，关于需要进行属属分离的差异程度仍存在不确定性，包括报告的解剖学颅骨差异。此外，属内分类仍然存在争议。大多数研究假设 Tropicoperdix 由三个物种组成，而其他研究则假设由一到四个物种组成。然而，尚未进行分子研究来澄清围绕 Tropicoperdix 的系统和分类学不确定性。在本研究中，我们基于两个线粒体基因和五个核内含子对 Tropicoperdix 和 Arborophila 类群进行了一系列分子系统发育分析。所有结果都与 Tropicoperdix 和 Arborophila 是系统发育上不同且遥远的属的发现一致，尽管 Tropicoperdix 的精确系统发育位置仍未确定。对外部特征的回顾性检查也支持属属分离，并提供了显着的多重特征趋同的证据。根据使用下一代测序方法从博物馆标本中获得的线粒体数据，我们建议 Tropicoperdix 至少包含两个完整物种。 © 2015 伦敦林奈学会
Although Tropicoperdix has been considered to be either a full genus or a species complex within the Phasianid genus Arborophila (hill partridges), there is long-standing uncertainty regarding the degree of difference that warrants generic separation, including reported anatomical cranial differences. In addition, the intra-generic taxonomy remains under dispute. Most studies hypothesize that Tropicoperdix comprises three species, while others postulate from one to four species. However, no molecular study has been performed to clarify the systematic and taxonomic uncertainties surrounding Tropicoperdix. In the present study, we performed a series of molecular phylogenetic analyses of Tropicoperdix and Arborophila taxa based on two mitochondrial genes and five nuclear introns. All the results are consistent with the finding that Tropicoperdix and Arborophila are phylogenetically distinct and distant genera, although the precise phylogenetic position of Tropicoperdix remains undetermined. Retrospective examination of external characteristics also supports the generic separation, as well as providing evidence of remarkable multiple character convergence. We propose that Tropicoperdix comprises at least two full species based on mitochondrial data obtained from museum specimens by using a next-generation sequencing method. © 2015 The Linnean Society of London
