A Systematic Study Of Siobla Cameron(Hymenoptera, Tenthredininae)

The research history of the genus Siobla Cameron is reviewed in detail. The morphology and the biological characters of the genus, as well as techniques of specimens collecting and pictures treatment are discussed. The depository of holotype of each Siobla species is listed. The distribution data and characteristics of zoogeography of Siobla species of world are also summarized and discussed.This paper reports the zoogeography of the genus Siobla which distributes in the area of China, N. Burma, N. India and Japan. The geological distribution of the genus Siobla can be divided into19patterns. A large part of species distribute in the main centre, which is the main distribution pattern among all the patterns.The taxonomy of Siobla is studied in detail in the thesis. A key to species groups of Siobla and keys to species of the9species groups are provided. Totally132species are described in detail in this thesis including72new species that have already published formally during2010-2012.
