直翅目昆虫亚目的代表（蟋蟀，Katydids和相关昆虫）因在求偶和配偶识别的背景下产生的声音信号而闻名。我们提出了一个系统发育的估计Ensifera的51个分类上不同的样本，使用18S，28S和16S rRNA序列。结果支持单系Ensifera，单系的大多数剑科，和总科Grylacridoidea，其中包括Stenopelmatidae，Anostostomatidae，Grylacrididae，和Lezina。Schizodactylidae被恢复为蟋蟀总科的姐妹谱系，Rhaphidophoridae和Tettigoniidae都被发现与蟋蟀总科的关系比以前的研究所建议的更密切。在ambiphilusly的发声haglid Cyphoderris被发现是基础（或姐妹）的一个分支，其中包括蟋蟀总科和Tettigoniidae。树比较测试与级联的分子数据发现，我们的同源性是显着更好地解释我们的数据比最近的系统发育假说的基础上形态特征。分子和形态学数据之间存在高度的冲突，可能表明在Ensifera中存在许多同质性，特别是在声学结构中。在以前的进化假说的基础上最吝啬的祖先状态重建，我们提出，tegalistridulation和胫骨鼓室的祖先Ensifera和丢失多次，特别是在蟋蟀科。(c)2005年爱思唯尔公司All rights reserved.
Representatives of the Orthopteran suborder Ensifera (crickets, katydids, and related insects) are well known for acoustic signals produced in the contexts of courtship and mate recognition. We present a phylogenetic estimate of Ensifera for a sample of 51 taxonomically diverse exemplars, using sequences from 18S, 28S, and 16S rRNA. The results support a monophyletic Ensifera, monophyly of most ensiferan families, and the superfamily Gryllacridoidea which would include Stenopelmatidae, Anostostomatidae, Gryllacrididae, and Lezina. Schizodactylidae was recovered as the sister lineage to Grylloidea, and both Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than has been suggested by prior studies. The ambidextrously stridulating haglid Cyphoderris was found to be basal (or sister) to a clade that contains both Grylloidea and Tettigoniidae. Tree comparison tests with the concatenated molecular data found our phylogeny to be significantly better at explaining our data than three recent phylogenetic hypotheses based on morphological characters. A high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures. In contrast to prior evolutionary hypotheses based on most parsimonious ancestral state reconstructions, we propose that tegminal stridulation and tibial tympana are ancestral to Ensifera and were lost multiple times, especially within the Gryllidae.
