| The present paper deals with a comprehensive taxonomic research of Scorpiones from China, five familes, twelve genera and 51 species (subspecies), including 1 genus newly recorded in China, 6 new species (subspecies) and 1 new combination species.1 genus newly recorded in China: Razianus Farzanpay, 19876 new species (subspecies): Mesobuthus caucasicus karshius ssp. nov., Mesobuthus longichelus Sun & Zhu, 2010,Mesobuthus bolensis Sun, Zhu & Louren?o, 2010,Razianus xinjianganus Louren?o, Sun & Zhu, 2010,Chaerilus mainlingensis sp. nov.,Euscorpiops xui Dong & Zhu, 20101 new combination species: Hottentotta songi (Louren?o, Qi & Zhu, 2005) (= Mesobuthus songi Louren?o, Qi & Zhu, 2005).And, this work involves keys to families, genera and species from China. It includes detailed descriptions about all species which checked carefully under microscope by modern taxonomic standards and grammars of scorpions, and it also includes accurate illustrations and measurements.Scorpions are a kind of preponderant invertebrate predator in desert and approximate environments, which are generally on the top of the energy pyramid and material pyramid. In the long time of evolution, they have developed a series of adaptive characters according to the droughty environments. This research expatiates on some problems about the evolution of scorpions from arid and semiarid deserts in northwest of China, which involving several aspects, such as morphology, physiology, biology, behavioral biology and so on.The present paper gives a phylogenic tree based on an analysis of Chinese genera. The tree includes two main branches: one belongs to Buthida and another belongs to Chaerilida and Iurida. This conclusion supports the current taxonomic system well.At the same time, this research covers the distributions and utilizations of scorpions in China, and includes analysis of some exemplification from field works. In the end, some constructive advices about resource conservations are projected. |
