Abstract

ABSTRACT In this report, the second of a revisionary series on mouse opossums (Marmosa), we analyze cytochrome b sequence data from 166 specimens of the subgenus Micoureus and delimit putative species using the multirate Poisson Tree Processes (mPTP) method. That analysis identifies 21 putative species, many of which can be matched with available names, including alstoni, constantiae, demerarae, limae, germana, meridae, paraguayana, parda, perplexa, phaea, rapposa, and rutteri. However, some of these nominal taxa are not morphologically diagnosable, and in the absence of other corroborating evidence, we do not recommend that they all be recognized as valid. Phylogenetic analyses of a multigene dataset suggest that putative species of Micoureus belong to several well-supported clades, one of which (the “Rapposa Group”) is revised in this report. As defined herein, the Rapposa Group includes at least three valid species: M. rapposa Thomas, 1899 (including budini Thomas, 1920); M. parda Tate, 1931; and M. rutteri Thomas, 1924. Herein we document their ecogeographic distributions and diagnostic traits, comment on their taxonomic histories, and list the specimens we examined (including all relevant type material).

迪德尔皮德有袋动物属Marmosa的修订（二）。Rapposa群的物种（Micoureus亚属）

摘要在本报告中，我们分析了166个鼠尾亚属标本的细胞色素b序列数据，并使用多比率泊松树过程（mPTP）方法确定了推测的物种。该分析确定了21个推定物种，其中许多可以与现有名称相匹配，包括alstoni、constantiae、demaraae、limae、germana、meridae、paraguayana、parda、confusa、phaea、rapposa和rutteri。然而，其中一些命名分类群在形态学上是不可诊断的，在缺乏其他确凿证据的情况下，我们不建议将它们全部认定为有效。多基因数据集的系统发育分析表明，Micoureus的假定物种属于几个得到充分支持的分支，其中一个分支（“Rapposa群”）在本报告中进行了修订。如本文所定义的，Rapposa群包括至少三个有效物种：M.Rapposa-Thomas，1899（包括布迪尼·托马斯，1920）；M.帕达·泰特，1931年；和M.rutteri Thomas，1924年。在此，我们记录了它们的生态地理分布和诊断特征，评论了它们的分类历史，并列出了我们检查的标本（包括所有相关的类型材料）。

期刊介绍： The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates, published short papers describing new forms.
