古气候振荡和不同的景观往往导致复杂的种群结构或神秘物种的进化。阐明潜在的机制对于理解物种形成事件至关重要。然而，这种复杂的进化模式很少在蝙蝠中报道。在中国，菊头蝠复合体包含一个大型和一个小型，这表明存在一个神秘的蝙蝠物种。野外调查发现，这两个兄弟种具有连续和广泛的分布，部分同域。然而，它们的进化历史却很少受到关注。在这里，我们使用了广泛的采样，形态学和声学数据，以及不同的遗传标记，以调查他们的进化历史。遗传分析显示线粒体和核数据之间的不一致。线粒体数据确定了三个单系谱系：一个代表来自中国西南部的所有小型类型，另两个分别包含来自中国中部和东南部的所有大型类型。大型与小型并系。然而，微卫星和Chd 1基因序列的聚类分析支持两个不同的集群分离的大的形式和小的形式。此外，形态和声学分析与核数据一致。这种不寻常的模式在R。macrotis复合体可能与古气候振荡、共同祖先多态性和/或种间杂交有关。
Palaeoclimatic oscillations and different landscapes frequently result in complex population-level structure or the evolution of cryptic species. Elucidating the potential mechanisms is vital to understanding speciation events. However, such complex evolutionary patterns have rarely been reported in bats. In China, the Rhinolophus macrotis complex contains a large form and a small form, suggesting the existence of a cryptic bat species. Our field surveys found these two sibling species have a continuous and widespread distribution with partial sympatry. However, their evolutionary history has received little attention. Here, we used extensive sampling, morphological and acoustic data, as well as different genetic markers to investigate their evolutionary history. Genetic analyses revealed discordance between the mitochondrial and nuclear data. Mitochondrial data identified three reciprocally monophyletic lineages: one representing all small forms from Southwest China, and the other two containing all large forms from Central and Southeast China, respectively. The large form showed paraphyly with respect to the small form. However, clustering analyses of microsatellite and Chd1 gene sequences support two divergent clusters separating the large form and the small form. Moreover, morphological and acoustic analyses were consistent with nuclear data. This unusual pattern in the R. macrotis complex might be accounted for by palaeoclimatic oscillations, shared ancestral polymorphism and/or interspecific hybridization.
