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 But the underlying classification is outdated, inadequate, and often wrong.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.

9707776 OTTE Katydids是世界上最引人注目的昆虫类群之一。自林奈以来的200年中，已描述了1193属和7188种蚱科。 每年都有许多新的物种被描述;更多的物种被存放在博物馆，等待描述。还有大量的物种有待采集。但基本的分类是过时的，不充分的，而且往往是错误的。 蚱科的现有分类主要基于19世纪和世纪早期的作品。没有分支系统学的方法已被应用到研究他们的关系。由于世界上绝大多数物种仍有待发现或描述，现在应该改进分类框架，为未来做好准备。 在丹尼尔奥特和皮奥特·纳斯克雷茨基的这项工作中，将产生一种新的Katydid分类，主要基于昆虫的形态特征和健全的系统发育原则。结果将分发在传统的印刷形式，并作为一个互动的，可搜索的目录和系统发育树可在互联网上和CD ROM。这项工作将提供第一个坚实的系统发育框架和参考基础，为今后的研究？
