中文摘要：

经对河北大学博物馆保存的台湾拟步甲定名标本和相关资料整理,共计得到6亚科28族125属476种（亚种）。通过在属级水平上对台湾与中国大陆各省份拟步甲区系的相似程度和历史渊源分析,得到如下初步结论：（1）在种类组成上,台湾拟步甲的物种数量从多到少依次是：树甲亚科Stenochiinae 177种（37.2%）〉拟步甲亚科Tenebrioninae 136种（28.6%）〉菌甲亚科Diaperinae 73种（15.3%）〉朽木甲亚科Alleculinae 45种（9.5%）〉伪叶甲亚科Lagriinae 43种（9.0%）〉心甲亚科Phrenapatinae 2种（0.4%）;（2）台湾拟步甲与福建的相似性最大,表明两地的区系分布有密切的历史渊源,而与大陆其他省份的关系较远;（3）构成台湾拟步甲区系的主体是东洋界华南区成分,属数高达125属（100%）,其与华中区和西南区的分布联系紧密,与前者共同分布的属达到66属（52.8%）,与后者共同分布的属达到61属（48.8%）,与华北区、青藏区、蒙新区和东北区的联系比较疏远,共有属分别为30属（24%）、22属（17.6%）、19属（15.2%）和19属（15.2%）;（4）台湾拟步甲的特有属较少,已知6属（4.8%）,而特有种显多,高达236种（47.6%）。

英文摘要：

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%）.
