A Taxonomic Study On Blattaria From Eastern China

Blattodea commonly known as the cockroach belongs to Blattaria, Dictyoptera, Insecta. There are about4500species worldwide and nearly300species from China.This thesis was dealed with the taxonomic and the biogeographic studies of Blattodea from8provinces (Shandong, Jiangsu, Shanghai, Zhejiang, Anhui, Fujian, Jiangxi and Taiwan) of eastern China.86species,27gunera,8subfamilies,4families,3superfamilies were described from eastern China. The keys to every taxonomic category were given. The biogeography was primary studied and their distributions were analysed.1. The traditional taxonomic study of BlattariaThis thesis was based on Mckittrick's (1964) form anatomy study and Roth's (2003) taxonomy study to research the Blattaria from eastern China. All the morphological terminologies used in this thesis were followed those of Roth (2003). All species are dry materials. Male genitirials were dissected with the stereomicroscope Motic SMZ-140. The morphological features were drawn and decorated by the Illustrator software. The specimen pictures were taken by digital camera.In this thesis,86species,27gunes belonging to8subfamilies,4families,3supfamilies (Corydioidea:Corydiidae; Blattoidea:Blattidae, Blattellidae; Blaberoidea: Blaberidae) were described. There are7new species and1new combination. The keys to species, genura, subfamily, family and superfamily were given and the literature citation, morphological characters and male genitalia figures, specimen pictures, signalment, specimen information and discribution were provided in detail.2new species of the gunes Symploce were found from other places of China by collating the specimens.The results showed that the species of Blattellidae are the most abundant and widely distributed in easten China. It's about75%of the total eastern species. But the Corydiidae only has a minimum ratio. It's about4%.9new species:Stictolampra bicolor Guo, Liu et Li,2011; Episymploce zhengi Guo, Liu et Li,2011; Episymploce longilamina Guo, Liu et Li,2011; Symploce hemiptera sp. nov.; Symploce fengyangshanica sp. nov.; Symploce huangshanica sp. nov.; Symploce nigra sp. nov.; Symploce nigrotibilis sp. nov. and Blata wuyishanica sp. nov..1new combination:Megamareta isomorpha (Walker,1868) comb. nov..All the specimens and the type specimens of the new species are deposited in Shanghai Entomological Museum Chinese Academy of Science (SHEM), Biological History Museum of East China Normal University (HSNU) and Shanghai Normal Univerciy (SHNUC).2. Biogeographic study on Blattaria from eastern ChinaThe biogeography of Blattaria from eastern China was studied. The eastern8regions are belonging to palaearctic region (Shandong, Jiangsu and Anhui) and oriental region (Shanghai, Zhejiang, Fujian, Jiangxi and Taiwan). The result showed that most species were distributed in Zhejiang, Fujian and Taiwan. Numerous species were distributed in oriental region, and a few were distributed in palaearctic region.Of the86species,73species were endemic to oriental region,1species was endemic to palaearctic region and12species were dispersed. So the oriental species were preponderant in easten China. And most species were lived in subtropical and tropical regions, few species distributed in temperate zones. The distribution of Blattaria from easten China is the same as the world.
