This dissertation is about the taxonomic and faunistic studies on the family Tenebrionidae from Xizang. The entire work includes six parts.The first part introduces the insect fauna of Xizang and their habitats in brief.The second part is about the materials and methods used in this dissertation. The field expedition routes from 2002 to 2005 and map of collecting sites are provided.The third part discusses the Tenebrionidae fauna of Xizang. The results are mainly as follows:1. The landforms, temperature and vegetation are analyzed. The complex landforms and high mountains exert the main influence on the abundance of endemic species. Temperature is one of limiting factors to Tenebrionidae. Tenebrionidae fauna of the Qiangtang region is poor, which can be mostly attributed to low temperature. The species are quite abundant in those environments are either extremely rich or poor in vegetation.2. The distribution patterns in the zoogeographical regions of the world are simple. There are four patterns: endemic species of Xizang (106 species, possessing 58.98%, the following is the same), Oriental region (32, 18.08%), Palaearctic region (26, 14.69%) and Oriental- Palaearctic region (13, 7.34%).3. In the zoogeographical regions of China, there are eight distribution patterns: Qinghai-Xizang region (81 species, possessing 47.65%, the following is the same), Southwest China region (51, 30.00%), Qinghai-Xizang-Southwest China region (12, 7.06%), Qinghai-Xizang-Inner Mongolia Xinjiang region (9, 5.29%), Southwest China-South China region (9, 5.29%), Southwest China-South China-Central China region (6, 3.53%), Southwest China-Inner Mongolia Xinjiang region (1, 0.59%), Qinghai-Xizang-Inner Mongolia Xinjiang-Central China region (1, 0.59%).4. By analyzing the environmental factors and the distribution of Tenebrionidae, also referring to the work done by previous reaserchers, the vast area of Xizang is divided into nine regions: 1) Metog-Dzayul region; 2) Pome-Menling region; 3) Middle Himalayas region;...
