Phylogeny and Biogeography of the Tiphiid Wasp Subfamily Thynninae (Hymenoptera)

本项目是蝶蜂亚科综合修订的第二部分。天牛科包括50多个属和750多个已描述种。大约30%的属和种仍未被描述。这些黄蜂出现在南美洲和澳大拉西亚，显然是在大约7500万年前通过连接南极洲的大陆桥到达这两个地区的。它们是居住在地面的圣甲虫的寄生虫，包括那些与日本甲虫有关的甲虫。横贯南极的分布，以及形态、分类和行为之间的独特关系，使这群黄蜂成为分析其进化和分布的理想选择。已经完成了对南美种群的分类和进化分析。本项目拟开展的研究包括澳大利亚属的进化分析，以及整个亚科在世界范围内的进化和生物地理分析。

This project is the second part of a comprehensive revision of the tiphiid wasp subfamily Thynninae. Thynninae includes more than 50 genera and 750 described species. Probably 30% of the genera and species remain undescribed. These wasps occur in South America and Australasia, apparently having reached both regions via land bridge connections with Antarctica some 75 million years ago. They are parasites of ground-dwelling scarab beetles, including those related to the Japanese Beetle. The transantarctic distribution, and distinctive relationship between morphology, taxonomy and behavior makes this group of wasps ideal for analyses of their evolution and distribution. Taxonomic and evolutionary analyses have been completed for the South American groups. The proposed research in this project on thynnines includes evolutionary analysis of the Australasian genera, and then overall evolutionary and biogeographic analyses of the entire subfamily worldwide.
