Abstract: We studied patterns of distribution and relationships among distributional areas of Tetrigidae insects in China using parsimony analysis of endemism (PAE). We constructed a matrix based on distribution data for Chinese Tetrigidae insects and an area cladogram using northeastern China area as an outgroup. Exhaustive searches were conducted under the maximum parsimony criterion. Cluster analysis divided eight biogeographic areas into four groups; group 1 was composed of northeast China, group 2 was composed of Mongolia-Xinjiang, group 3 was composed of central, eastern, and northern China, and group 4 was composed of southern and southwestern China and Qinghai-Xizang. The area cladogram suggested that northeastern China and Mongolia-Xinjiang formed earlier than others. This phenomenon is likely related to Pleistocene glacier movements. In general, Tetrigidae insect diversity was higher in southern China than northern China. We speculate that this pattern can be partially explained by the Pleistocene forest refuge theory and eco-environmental deterioration.
