Abstract

Integrating different lines of evidence is currently recognized as the most robust approach to investigating taxonomic questions, particularly those concerning cryptic diversity. In recent years, different sources of evidence have pointed to new cryptic taxa for bats, with the genus Hsunycteris being an excellent study group because of its large karyotypic variability and high genetic divergence revealed by the latest taxonomic and systematic reviews. This study tests the cryptic diversity hypothesis for the Hsunycteris thomasi complex through an integrative approach using species delimitation, phylogenetic analysis, chromosome painting, and linear morphometry. Our results suggest the existence of three lineages for H. thomasi that are morphologically indistinguishable, confirming the two previously described lineages in the literature and adding a third. We argue that the paraphyly in H. thomasi, as reported by previous studies, should be treated as independent species since they have unique evolutionary histories. Finally, we demonstrate that chromosomal and molecular methods are indispensable for recognizing and confirming groups that include cryptic species or species with confusing and controversial taxonomy.

蝙蝠Hsunycteris thomasi（Lonchophyllinae，Chiroptera）的隐性多样性案例：对未确认物种的新认识

整合不同的证据目前被认为是研究分类学问题，特别是有关隐性多样性问题的最有力的方法。近年来，不同来源的证据都指出了蝙蝠的新隐性类群，其中蝙蝠属（Hsunycteris）是一个极好的研究类群，因为最新的分类学和系统学综述揭示了该类群较大的核型变异性和较高的遗传分化。本研究通过物种划分、系统进化分析、染色体绘制和线性形态测量等综合方法，检验了Hsunycteris thomasi复合体的隐性多样性假说。我们的研究结果表明，H. thomasi 存在三个形态上无法区分的品系，证实了之前文献中描述的两个品系，并增加了第三个品系。我们认为，由于 H. thomasi 具有独特的进化历史，因此应将其视为独立的物种。最后，我们证明了染色体和分子方法对于识别和确认包括隐蔽物种或分类混乱且有争议的物种的类群是不可或缺的。

期刊介绍： Zoologica Scripta publishes papers in animal systematics and phylogeny, i.e. studies of evolutionary relationships among taxa, and the origin and evolution of biological diversity. Papers can also deal with ecological interactions and geographic distributions (phylogeography) if the results are placed in a wider phylogenetic/systematic/evolutionary context. Zoologica Scripta encourages papers on the development of methods for all aspects of phylogenetic inference and biological nomenclature/classification. Articles published in Zoologica Scripta must be original and present either theoretical or empirical studies of interest to a broad audience in systematics and phylogeny. Purely taxonomic papers, like species descriptions without being placed in a wider systematic/phylogenetic context, will not be considered.
