ON THE DISTRIBUTIONAL PATTERNS OF THE GENERA OF CHINESE EUMOLPINAE (COLEOPTERA: EUMOLPIDAE)

Up to the present, a total of 48 genera and 349 species of Eumolpinae are re-corded from China. Based on the range of distributions of these genera, they can be classified into four major distributional patterns and a number of secondary patterns. Through the distributional patterns the faunal origin of the Chinese Eumolpinae can be traced. The present paper includes three parts, namely:1, catalogue of the Chinese genera of Eumolpinae; 2.destributional patterns and geographical elements; 3. faunal origin. In the Chinese Eumolpinae fauna, the Oriental elements range first, occupying 43.7% and 49.54% of the to-tal number of genera and species respectively. This fact clearly indicates the Oriental origin of this group in China. On the generic level, there are also close relationships between the Chinese Oriental fauna and Ethiopian fauna. There are 6 genera in common in both regions. The routes of dispersal and exchange between both faunas arc also discussed. There are 3 Chinese endemic genera, one of which is as yet only found in Yunnan, and this province is al-so one of the main distributional regions of the other two genera. So it is regarded that Yunnan is one of the important places of origin of Chinese Eumolpinae.
