青藏高原及其毗邻地区拟步甲共7亚科47族268属1950种(亚种),以拟步甲亚科Tenebrioninae(842种)为最多,然后依次为伪叶甲亚科Lagriinae(377种)、漠甲亚科Pimeliinae(372种)、树甲亚科Stenochiinae(143种)、菌甲亚科Diaperinae(139种)、朽木甲亚科Alleculinae(76种)和弗甲亚科Phrenapatinae(1种)。青藏高原及其毗邻地区拟步甲的区系组成突出中日界成分(54.10%),其与世界其他动物地理区系的关系以东洋界+中日界共有成分最多(17.16%),其次为古北界+撒哈拉-阿拉伯界(10.82%)。青藏高原拟步甲突出青藏区成分(62.33%),与西南区关系最直接(19.14%),蒙新区次之(7.12%)。基于青藏高原及其毗邻地区拟步甲的区系特点,讨论了其作为一个独立的动物地理区的可能性。
In total,1950 species( subspecies) of darkling beetles belonging to 268 genera,47 tribes and 7 subfamilies have been recorded from Qinghai- Xizang Plateau and adjacent areas. Tenebrioninae( 842 species) was the most,then Lagriinae( 377 species),Pimeliinae( 372 species),Stenochiinae( 143 species),Diaperinae( 139 species),Alleculinae( 76 species) and Phrenapatinae( 1 species).They were mainly distributed in Sino- Japanese realm and Oriental realm( 17. 16%),Palearctic realm and Saharo- Arabian realm( 10. 82%) were lesser in the world fauna and the Sino- Japanese realm was distinct( 54. 10%). They were also mainly distributed in Southwest region( 19. 14%) and then Mongolia- Xinjiang region( 7. 12%) in China fauna and the Qinghai- Xizang region was distinct( 62. 33%). Based on the faunal characteristic of darkling beetles from Qinghai- Xizang Plateau and adjacent areas,we discussed the possibility of this area to be a single zoogeographical region.
