Diversity and faunal composition of darkling beetles( Tenebrionidae,Coleoptera) Taiwan,China

By identifying the determined specimens of darkling beetles which are collected in the Museum of Hebei University and collecting the data in relevant literature from Taiwan,In total,476 species belonging to 125 genera,28 tribes and 6 subfamilies are documented. Comparing the similarity of darkling beetles fauna between Taiwan and mainland of China by using clustering analysis in the genera level,the preliminary results were showed as followed: 1. The quantity of species of each subfamily were ordered from more to less: Stenochiinae( 177 species),occupying 37. 2% Tenebrioninae( 136species),occupying 28. 6% Diaperinae( 73 species),occupying 15. 3% Alleculinae( 45 species),occupying 9. 5% Lagriinae( 43 species),occupying 9. 0% Phrenapatinae( 2 species),occupying0. 4%; 2. The fauna of Taiwan darkling beetles is evidently close to that of Fujian,and far from the fauna of other provinces. It indicates that the geography of Taiwan and Fujian has a quite close relationship; 3. The fauna of Taiwan darkling beetles is typical fauna of South China Region belonging to Oriental Realm( 125 genera,accounting for 100%). The distributional relation of darkling beetles from Taiwan is closest to Central China Region( 66 shared genera,52. 8%) and Southwest Region( 61 shared genera,48. 8%),meanwhile far from North China( 30 shared genera,24%),Qinghai- Xizang( 22 shared genera,17. 6%),Mongolia- Xinjiang( 19 shared genera,15. 2%) and Northeast Region( 19 shared genera,15. 2%); 4. Endemic genera of Taiwan darkling beetles are relatively few with only 6genera( 4. 8%) recorded,however,endemic species are evidently abundant,including 236 species( 49. 5%).
