我们提出了一个分子系统的调查家庭组类群的膜翅目，包括近3.5 kb的核基因延伸因子-1 α（EF-1 α：958 bp）和28 S核糖体DNA（28 S rDNA：2363 bp）的核苷酸序列数据之间的关系进行了分析，分别和组合的79个类群的数据分区。结合序列数据的分析提供了一个更好的解决和更强大的假设membracidembrogeny比单独的分析个别基因。结果支持单系性的家庭Membracidae，并表明存在两个主要谱系（Centrotinae + Stegaspidinae + Centrodontinae和Darninae + Membracinae + Smiliinae）。分子生物学数据支持以下结论：（1）以前未被定位的属Antillotolania和Deiroderes与Microcentrini形成一个单系群;（2）Centrodontini和Nessorhinini是独立于Centrotinae内的单系分支;（3）Centrotinae相对于Centrodontinae并系;（4）膜翅目（Membracinae）亚科是单系的，可能与缘鼻象族（Cymbomorphini）近缘，（5）缘鼻象亚科是并系的;（6）Smiliinae亚科是并系的，分子证据表明Micrutalini可能被排除在外，Acutalini和Ceresini也可能被排除在外;（7）膜虫科在新大陆出现并多样化，随后又多次在旧大陆殖民。我们的系统发育的结果表明，基于形态学的分类的膜翅目需要重新评估，在新兴的分子证据。(C)北京大学出版社.
We present a molecular systematic investigation of relationships among family-group taxa of Membracidae, comprising nearly 3.5 kb of nucleotide sequence data from the nuclear genes elongation factor-1 alpha (EF-1 alpha: 958 bp) and 28S ribosomal DNA (28S rDNA: 2363 bp); data partitions are analyzed separately and in combination for 79 taxa. Analysis of the combined sequence data provided a better-resolved and more robust hypothesis of membracid phylogeny than did separate analyses of the individual genes. Results support the monophyly of the family Membracidae and indicate the presence of two major lineages (Centrotinae + Stegaspidinae + Centrodontinae and Darninae + Membracinae + Smiliinae). Within Membracidae, molecular data support the following assertions: (1) the previously unplaced genera Antillotolania and Deiroderes form a monophyletic group with Microcentrini; (2) Centrodontini and Nessorhinini are monophyletic clades that arise independently from within the Centrotinae; (3) Centrotinae is paraphyletic with respect to Centrodontinae; (4) the subfamily Membracinae is monophyletic and possibly allied with the darnine tribe Cymbomorphini; (5) the subfamily Darninae is paraphyletic; (6) the subfamily Smiliinae is paraphyletic, with molecular evidence indicating the exclusion of Micrutalini and perhaps Acutalini and Ceresini; and (7) Membracidae arose and diversified in the New World with multiple subsequent colonizations of the Old World. Our phylogenetic results suggest that morphology-based classifications of the Membracidae need to be reevaluated in light of emerging molecular evidence. (C) 2000 Academic Press.
