Abstract

Myotis is one of the most diverse genus of bats in the world, with ca. 35 species recognized for the Neotropics. Among these, Myotis dinellii Thomas, 1902 has been alternatively treated as a valid species or as a synonym of Myotis levis (I. Geoffroy, 1824). Previous phylogenetic analysis of DNA sequences suggests that both taxa could constitute a single species. To test this hypothesis, we employed both qualitative and quantitative morphological approach and a re-examination of the available genetic data, in order to integrate multiple lines of evidence. Principal component and discriminat analyses failed to separate morphologically M. dinellii from M. levis. Also, mitochondrial sequences of the cytochrome b gene showed very low divergence, and the taxa did not form reciprocally monophyletic groups. Therefore, morphological and genetic analyzes provides a strong support to the conspecificity between M. dinellii and M. levis. This hypothesis is also supported by our direct examination of some topotypes of M. dinelli and color photograph of the syntype of M. levis. The morphological variation found within the studied samples is more likely explained by geographic variation, involving a west-east gradient in overall size. Based on these findings, we propose that M. dinellii is a junior synonym of M. levis.

阿根廷大翅蝗和大翅蝗种群的综合分类及地理变异

蝙蝠属（Myotis）是世界上最多样化的蝙蝠属之一，在新热带地区约有 35 个物种。其中，Myotis dinellii Thomas, 1902 一直被当作一个有效种或 Myotis levis (I. Geoffroy, 1824) 的异名。之前的 DNA 序列系统发育分析表明，这两个类群可能是一个物种。为了验证这一假设，我们采用了定性和定量的形态学方法，并重新审查了现有的遗传学数据，以整合多种证据。主成分分析和判别分析未能从形态学上将 M. dinellii 与 M. levis 区分开来。此外，细胞色素 b 基因的线粒体序列也显示出极低的差异，这两个类群没有形成互为单系的类群。因此，形态学和遗传学分析为 M. dinellii 和 M. levis 之间的同种性提供了强有力的支持。我们对 M. dinelli 的一些 topotype 和 M. levis 的同种异形的彩色照片进行了直接检验，也支持了这一假设。在所研究的样本中发现的形态变异更有可能是由地理变异造成的，涉及到总体大小的西-东梯度。基于这些发现，我们认为M. dinellii是M. levis的初级异名。

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
