Abstract

Myotis is the most speciose genus of mammals in the world and recent taxonomic revisions have revealed an impressive diversity of species in South America. Even so, the phenotypic conservatism of some taxa makes taxonomic delimitation difficult. We perform a taxonomic review of Myotis from Argentina based on qualitative and quantitative morphological characters. Our results confirm the occurrence of 12 species (M. albescens, M. chiloensis, M. dinellii, M. izecksohni, M. keaysi, M. lavali, M. levis, M. nigricans, M. oxyotus, M. riparius, M. ruber, and M. cf. simus) and revealed an additional new species for the Yungas Forest. The new species is small to medium (forearm length ~ 35 mm) and can be distinguished from its congeners by a set of characters that includes forearm length, cranial measurements, discrete craniodental characters, and fur color. This review does not exhaust the need for new systematic studies with Argentinean Myotis, considering the possibility of occurrence of new species and the great morphological variation found for some complex taxa.

阿根廷小蛾属(翼翅目，小蛾科)，包括一新种的描述

心肌炎是世界上物种最多的哺乳动物属，最近的分类学修订揭示了南美洲令人印象深刻的物种多样性。即便如此，一些分类群的表型保守性也使得分类学划界变得困难。我们根据定性和定量形态学特征对阿根廷心肌炎进行了分类综述。我们的结果证实了12个物种（M.albescens、M.chiloensis、M.dinellii、M.izecksohni、M.keaysi、M.lavali、M.levis、M.nigricans、M.oxiotus、M.riparius、M.ruber和M.cf.simus）的出现，并揭示了云加斯森林的另一个新物种。这个新物种是小到中等（前臂长度~35毫米），可以通过一系列特征与同类物种区分开来，这些特征包括前臂长度、颅骨测量、离散的颅骨特征和毛皮颜色。考虑到新物种出现的可能性和一些复杂类群的巨大形态变异，这篇综述并没有耗尽对阿根廷心肌炎进行新的系统研究的必要性。
