ABSTRACT Taxonomy of the Striated Grasswren Amytornis striatus complex has long been contentious and remains incompletely resolved. Its many populations are distributed widely but disjunctly and show only subtle distinction in morphology and plumage. Genetic data are meagre and have not been correlated with phenotype. We conducted a phenotypic analysis across its range and obtained mitochondrial DNA sequences from most populations. We recognise three species: south-eastern Striated Grasswren Amytornis striatus sensu stricto, Opalton Grasswren Amytornis rowleyi in central Queensland and Rufous Grasswren Amytornis whitei in the remainder of the range, with subspecies in the Pilbara and in the central and western deserts. In A. striatus as so circumscribed, we separate allopatric Murray Mallee and central New South Wales populations subspecifically. Isolated populations of Rufous Grasswren, from the North West Cape Peninsula, Western Australia and Eyre Peninsula, South Australia are also distinct. Awareness of such unanticipated diversity within the group has profound implications for conservation.

对系统发育和表型数据进行分析后，对纹状草螟复合体（Aves：Maluridae）进行分类学修订

摘要 条纹草 Amytornis 纹状体复合体的分类长期以来一直存在争议，仍未完全解决。它的许多种群分布广泛但不连续，仅在形态和羽毛上表现出细微的区别。遗传数据很少，并且与表型无关。我们对其范围进行了表型分析，并从大多数人群中获得了线粒体 DNA 序列。我们识别出三个物种：东南条纹草 Amytornis striatus sensu stricto、昆士兰中部的 Opalton Grasswren Amytornis rowleyi 和该范围其余部分的 Rufous Grasswren Amytornis whitei，亚种位于皮尔巴拉以及中部和西部沙漠。在 A. striatus 如此限定，我们将异域 Murray Mallee 和新南威尔士中部种群亚种分开。来自西澳大利亚开普半岛西北部和南澳大利亚艾尔半岛的 Rufous Grasswren 的孤立种群也很明显。意识到群体内这种意想不到的多样性对保护具有深远的影响。
