文章摘要：

The taxonomic status of subspecies has long been debated, especially in conservation biology. Some pro- posed subspecies must be evolutionarily distinct to be considered conservation units. White-necklaced Partridge (Arborophila gingica) comprises two subspecies, A. g. gingica and A. g. guangxiensis. A. g. guangx- iensis, restricted to three isolated small areas in Guangxi, China, with limited population sizes, is a newly discovered subspecies based on recently identi ed geographic and phenotypic di erences between A. g. gingica; however, evidence is lacking that can e ectively identify whether the subspecies is evolutionarily distinct. Here, three mitochondrial DNA segments and four nuclear introns were used to test whether the two subspecies are reciprocally monophyletic, which has been proposed as an objective method to evalu- ate evolutionary distinctiveness.  e results indicate that the two subspecies are genetically divergent and form reciprocal monophyletic groups.  erefore, this study further supports the taxonomic validity and distinctiveness of A. g. guangxiensis and suggests that this subspecies be considered as a conservation unit.
