中国蝗总科昆虫科间系统发育关系支序分析：直翅目;蝗亚目

在形态学研究的基础上，配方选择了１２个特征，利用Ｈｅｎｎｉｇ８６程序包，以支序分析探讨了中国蝗总科昆虫科间的系统发育关系。结果表明蝗虫类昆虫稳定的分为两大类，即癞蝗类和蝗类，本文建议蝗虫类昆虫分为分为两个总科较宜。长腹蝗亚科似归入斑腿蝗亚科更为合理；而皱腹亚科则应提升为独立科。

CLADISTIC ANALYSIS OF THE PHYLOGENETIC RELATIONSHIPS AMONG THE FAMILIES OF ACRIDOIDEA (ORTHOPTERA: ACRIDOMORPHA)

Based on the morphological study, 12 apomorphies, including head, thorax and abdomen are selected for the attempt to interpret the phylogenetic relationships among the families of the superfamily Acridoidea by a cladistic approach. Results show that: 1) acridinea is stably subdivided into 2 groups, and two groups should be treated as separate superfamilies, viz: Acridoidea and Pamphagoidea; 2) it is reasonable that subfamily Leptacrinae is listed in family Catantopidae. And, subfamily Egnatinae should be elevated to family, viz: Egnatidae; 3) in classicial taxonomic systems, Chrotogonidae and Pyrgomorphidae are regarded as a sister group. Cladistic analysis's results show that Chrotogonidae and Pamphagidae are regarded as a sister group, which their ancestor and Pyrgomorphidae are with common origin.
