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

[9707776]蝈蝈是世界上最引人注目的昆虫类群之一。自林奈以来的200年里，已经记录了毡虫科（kattigoniidae） 1193属和7188种。每年都有许多新物种被描述；更多的物种被存放在博物馆里，等待着人们的描述。仍有大量物种有待收集。但根本的分类是过时的、不充分的，而且常常是错误的。现有的tetigoniidae分类主要基于19世纪和20世纪初的作品。在研究它们之间的关系时，没有采用进化的方法。由于世界上绝大多数物种仍未被发现或描述，现在应该改进分类框架，为未来做准备。在Daniel Otte和Piotr Naskrecki的这项工作中，将产生一种新的蝈蝈分类，主要基于昆虫的形态特征和基于健全的系统发育原理。研究结果将以传统的印刷形式发布，并以交互式、可检索的目录和系统发育树的形式在互联网和CD ROM上发布。这项工作将为今后的研究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 But the underlying classification is outdated, inadequate, and often wrong.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.
