REVSYS: Revisionary Synthesis of the Holarctic Leafhopper Genus Erythroneura Fitch (Hemiptera, Cicadellidae)

一点脉叶蝉属（Erythroneura）在全世界有600种，其中487种分布在北美洲。 这些昆虫是森林生物多样性的主要组成部分，也是园艺作物，特别是葡萄藤的重要害虫。 该属的巨大多样性以前阻碍了试图开发一点脉属物种的全面分类和鉴定指南。 由于有了几种新的节省劳力的工具，这样一个项目在所需时间和成本方面都是可行的。 这个为期3年的项目的具体目标是：（1）编辑一个包含所有一点脉属物种插图的数字图像档案，并将其链接到已经完成的科学名称数据库;（2）输入地理参考的收集记录，例如：（3）编制一点脉属物种的解剖特征矩阵，并分析这些数据以估计物种之间的进化关系;（4）创建用于在网络上识别物种的交互式工具;（5）出版一点脉属物种的彩色图谱和识别指南。通过整合各种节省劳动力的工具，该项目将成为对高度多样化的生物群体进行全面有效分类的模式。 该项目还将促进研究植食昆虫中寄主植物协会的演变，以及特定植物的专门化在多大程度上促进了这一群体的进化多样化。 该项目的更广泛影响包括：（1）升级伊利诺伊州自然历史调查的基础设施，以提高修订研究的效率，并使科学界和公众更容易获得这些研究的成果;（2）培训一名来自发展中国家的博士后研究员，研究一个多样化但鲜为人知的昆虫群体，在系统专著中采用先进的工具和方法;（3）改进农业害虫和入侵物种的识别和跟踪方法。

The leafhopper genus Erythroneura comprises 600 species worldwide, 487 of which occur in North America. These insects are a major component of forest biodiversity and are also important pests of horticultural crops, particularly grapevine. The tremendous diversity of this genus has previously hindered attempts to develop a comprehensive classification and identification guide for Erythroneura species. The availability of several new labor-saving tools has now rendered such a project feasible in terms of the time required and cost. The specific goals of this 3-year project are: (1) compile a digital image archive containing illustrations of all Erythroneura species and link it to an already completed database of scientific names; (2) enter georeferenced collection records for ca. 40,000 museum specimens of the genus, one record for each unique collecting event/species combination, into the database; (3) compile a matrix of anatomical features for Erythroneura species and analyze these data to estimate the evolutionary relationships among species; (4) create interactive tools for identifying species over the Web; (5) publish a color atlas and identification guide for species. By incorporating various labor-saving tools, this project will serve as a model for comprehensive and efficient classification of hyperdiverse groups of organisms. The project will also facilitate study of the evolution of host-plant associations in plant-feeding insects and the extent to which specialization on particular plants has facilitated evolutionary diversification in this group. Broader impacts of the project include: (1) upgrading the infrastructure of the Illinois Natural History Survey to improve the efficiency of revisionary studies and the accessibility of the products of such studies to the scientific community and general public; (2) training of a post-doctoral fellow from a developing country, studying a diverse but poorly known insect group, in the use of advanced tools and methods in systematic monography; (3) improvements in methods for identifying and tracking the spread of agricultural pests and invasive species.
