已知三种不同的竹蝠（Tylonycteris）栖息在亚洲的热带和亚热带地区，即，T. pachypus，T. robustula和T.侏儒。本文对4份中国南方红豆杉标本进行了核型分析。p. fulvidus种群和一个来自Thai T.与之前T. fulvidus的核型描述相比，该群体检测到了不同的核型（2n=30）。p. pachypus（2n=46）和T. robustula（2n=32）采自马来西亚。这一发现表明，一个神秘的Tylonycteris物种在T。分布于中国和泰国。形态计量学研究表明，在区分隐种和T。P. pachypus的化石来源于印度尼西亚，这可能是它们历史上被错误鉴定的原因。基于623 bp的线粒体COI片段，对T.来自中国和邻近地区的pachypus个体，即，越南、老挝和柬埔寨进行了研究，以检查种群遗传结构。系谱学和地理学分析结果表明，这些地区至少存在两个分歧的谱系（平均3.4%的木村2-参数距离），它们的种群结构与地理格局不匹配。这些结果表明，至少有两个历史殖民地发生的隐种。此外，通过传统形态学和几何形态学结果的整合，发现中国两个谱系在牙弓、齿列和大疱等方面存在形态学差异。鉴于广东和广西地区植被和气候的相似性，我们认为这种差异可能源于它们的历史适应或不同的进化历史，而不是它们当前栖息地的差异。
Three distinct bamboo bat species (Tylonycteris) are known to inhabit tropical and subtropical areas of Asia, i.e., T. pachypus, T. robustula, and T. pygmaeus. This study performed karyotypic examinations of 4 specimens from southern Chinese T. p. fulvidus populations and one specimen from Thai T. p. fulvidus population, which detected distinct karyotypes (2n=30) compared with previous karyotypic descriptions of T. p. pachypus (2n=46) and T. robustula (2n=32) from Malaysia. This finding suggested a cryptic Tylonycteris species within T. pachypus complex in China and Thailand. Morphometric studies indicated the difficulty in distinguishing the cryptic species and T. p. pachypus from Indonesia apart from the external measurements, which might be the reason for their historical misidentification. Based on 623 bp mtDNA COI segments, a phylogeographic examination including T. pachypus individuals from China and nearby regions, i.e., Vietnam, Laos, and Cambodia, was conducted to examine the population genetic structure. Genealogical and phylogeographical results indicated that at least two diverged lineages existed in these regions (average 3.4 % of Kimura 2-parameter distances) and their population structure did not match the geographic pattern. These results suggested that at least two historical colonizations have occurred by the cryptic species. Furthermore, through integration of traditional and geometric morphological results, morphological differences on zygomatic arches, toothrows and bullae were detected between two lineages in China. Given the similarity of vegetation and climate of Guangdong and Guangxi regions, we suggested that such differences might be derived from their historical adaptation or distinct evolutionary history rather than the differences of habitats they occurred currently.
