A Taxonomic Study On Anthomyiidae From The Qinghai-tibet Plateau Region, China (Diptera, Muscoidea)

The Anthomyiidae belong to Muscoidea, Cyclorrhapha, Diptera, Insecta. There are about 2000 species worldwide and nearly 678 species from China.This thesis deals with the taxonomic studies of Anthomyiidae from the Qinghai-tibet Plateau Region, China. This thesis aims to investigate the present situation, make up for any deficiencies and provide more profect basic data of the Anthomyiidae from the Qinghai-tibet Plateau Region. The data can provides some references for the biodiversity research, agriculture, forestry and medicine health protection. The main research contents and research results were as follows:1. The traditional taxonomic study of Anthomyiidae from the Qinghai-tibet Plateau Region, ChinaThe source of the specimen in this thesis including two parts. Some specimens are dry materies in the library. The others were collected by myself. Male genitirials were dissected with the stereomicroscope Motic SMZ-140. The morphological features were drawn by Sudoku method. All the morphological terminologies used in this thesis were adopted mainly from "Economic Insect Fauna of China (Diptera: Anthomyiidae)" edited by Fan,1988.In this thesis,364 species,27 genera are reported from the Qinghai-tibet Plateau Region, including 3 new species,3 new combination and 1 subspecies is upgraded to species. Each genus and 71 species are described. The keys to every taxonomic category were given. The literature citation, synonym, specimen information and distribution are indicated. At the same time, we completed the supplementary catalogue of the Anthomyiidae of China from reading the literature.3 new species:Egle minutina sp. nov. is similar to Egle minuta (Meigen,1826) except for the following characteristics. Under the costa without seta. The 5th tergite with seta in lateral view.In lateral view, surstylus with process. In addition to the following characteristics, Egle latilateralis sp. nov. is similar to Egle minutina sp. nov. Interfrontalia black. Under the scutellum without cilia.In lateral view, surstylus without process. In rear view, anal cerci infundibulate. Pegomya paracunicularia sp. nov. is similar to Pegomya cunicularia (Rondani,1866) except for the following characteristics. Interfrontalia black. Ocelli about 4 times as long as frons. Forehead is more than the anterior mouth. Pregonite without cilia and phallosome has small slit.3 new combination:Enneastigma fulva (Malloch,1934), comb. nov. and Enneastigma henanensis (Ge & Fan,1982), comb. nov.. Because the surstylus are not forming a projecting lobe, a derived character state only defining the genus Pegoplata. We think they belong to the genus Enneastigma. Hylemya qinghaiensis (Fan, Chen & Ma,1989), comb, nov., Fan et al. (1989) established a new genus Lopesohylemya with the new species Lopesohylemya qinghaiensis as type species. The distal articles of both antennae are missing in the holo-type and only known specimen of Lopesohylemya qinghaiensis. Accordingly, we don’t agree with the genus Lopesohylemya. We think it is similar to Hylemya flavicruralis Suwa,1989, so it belong to the genus Hylemya.1 subspecies is upgraded to species:Adia asiatica Fan in Fan et al.,1988, stat. rev., the present taxon differs significantly from Adia grisella (Rondani,1871) in the structure of the male terminalia. It also has a distribution overlapping with Adia grisella in Central Asia.All the specimens and the type specimens of the new species are deposited in Shanghai Entomological Museum Chinese Academy of Science (SHEM) and Biological History Museum of East China Normal University (HSNU).2. The Biogeography research of Anthomyiidae from the Qinghai-tibet Plateau Region, ChinaThe biogeography of Anthomyiidae from the Qinghai-tibet Plateau Region was firstly primary studied in China. There are 364 species from this region, and it’s about 53.96% of the total China species. Of the 364 species, about 80.77% of the total species in this region were endemic to palaearctic region and about 19.23% of the total species were dispersed. So the palaearctic species were preponderant in the Qinghai-tibet Plateau Region. The local species of the Qinghai-tibet Plateau Region are 172, about 47.25% of the total species in this region and about 25.37% of the total species in China. In view of the research data and the life habits, we believe that there are more new species will be finding.
