近年来，利用分子生物学技术证实了鼠形目Rapaninae亚科的单系性，但其组成和各属间的关系仍不清楚。我们使用四个基因（28S rRNA，12S rRNA，16S rRNA和细胞色素c氧化酶亚基I，COI）构建贝叶斯遗传学的80 rapanine物种（73%的约109目前接受），代表27的31个名义属。这是迄今为止最完整的分类学上混乱的亚科。我们提出了一个修订的系统发育分类的Rapaninae，分配公认的种到28属。大多数形态学定义的rapanine属被认为是有效的，包括Purpura，Drupa，Thais和Nassa，但其中许多在这里被限制或重新定义，使它们成为单系。特别是熟悉的属Thais被严格限制为一个单一的物种。许多以前被接受为亚属的类群，包括Mancinella、Vasula、Thalessa和Thaisella，在这里被赋予完整的属级。我们描述了一个新属，Indothais。虽然我们没有正式改变物种水平的分类，我们显示两个神秘的物种和几个可能的物种同义的实例的分子证据。我们估计年龄的Rapaninae的晚白垩世（75.9马）和中新世的许多属的多样化。(C)2012 Elseviei Inc.

The monophyly of the muricid subfamily Rapaninae has recently been confirmed with molecular techniques, but its composition and the relationships among its constituent genera remain unclear. We use four genes (28S rRNA, 12S rRNA, 16S rRNA and cytochrome c oxidase subunit I, COI) to construct a Bayesian phylogeny of 80 rapanine species (73% of the approximately 109 currently accepted), representing 27 of the 31 nominal genera. This is the most complete phylogeny of this taxonomically confusing subfamily yet produced. We propose a revised phylogenetic classification of the Rapaninae, assigning the recognized species to 28 genera. Most of the morphologically-defined rapanine genera are considered valid, including Purpura, Drupa, Thais and Nassa, but many of them are here restricted or redefined so that they are monophyletic. In particular the familiar genus Thais is narrowly restricted to a single species. Many groups previously accepted as subgenera, including Mancinella, Vasula, Thalessa and Thaisella, are here accorded full generic rank. We describe one new genus, Indothais. While we do not formally alter species-level taxonomy, we show molecular evidence for two cryptic species and several instances of probable species synonymy. We estimate the age of diversification of the Rapaninae as Late Cretaceous (75.9 Ma) and of many of its genera as Miocene. (C) 2012 Elseviei Inc. All rights reserved.
