Phylogenetic Systematics of World Katydids and New Classification and Catalog of World Species

9707776只袋鼬是世界上最引人注目的昆虫群体之一。自Linneeus以来的200年里，共记述了叶蝉科1193属7188种。每年都有大量的新物种被描述；更多的物种被保存在博物馆里，等待描述。大量物种有待收集。但基本的分类是过时的、不充分的，而且往往是错误的。现有的叶蝉科分类主要基于19世纪和20世纪初的著作。没有分支方法论被应用于研究他们之间的关系。由于世界上绝大多数物种仍有待发现或描述，现在是时候改进分类框架并为未来做准备了。在Daniel Otte和Piotr Naskrecki的这项工作中，将产生一个新的katyids分类，主要基于昆虫的形态特征和合理的系统发育原理。这些结果将以传统的印刷形式分发，并以可在因特网和光盘上查阅的交互式、可搜索的目录和系统发育树的形式分发。这项工作将为进一步研究叶蝉科提供第一个坚实的系统发育框架和参考基础。

9707776 OTTE Katydids are one of the most conspicuous groups of insects world-wide. In the 200 years since Linnaeus, 1193 genera and 7188 species of Tettigoniidae (katydids) have been described. Numerous new species are being described each year; many more species are deposited in museums and await description. A large number of species remain to be collected. But the underlying classification is outdated, inadequate, and often wrong. Existing classifications of Tettigoniidae are based largely on 19th and early 20th century works. No cladistic methodology has been applied to studies on their relationships. Because the vast majority of world species remain to be discovered or described, it is appropriate now to improve the taxonomic framework and prepare for the future. In this work by Daniel Otte and Piotr Naskrecki, a new katydid classification, based primarily on morphological characters of the insects and based on sound phylogenetic principles, will be produced. The results will be distributed both in traditional printed form and as an interactive, searchable catalog and phylogenetic tree available on the Internet and CD ROM. This work will provide the first solid phylogenetic framework and a reference base for future research on Tettigoniidae.
