摘　　要：本文在对河北(含京、津地区)拟步甲科昆虫进行种类鉴定和地理分布资料整理的基础上,得出该地区已知拟步甲科昆虫5亚科19族38属64种(亚种),并以此为依据分析了该地区拟步甲的物种多样性组成及地理分布特点。结果显示,河北拟步甲在种类组成上由多到少依次为:拟步甲亚科Tenebrioninae 20属40种(62.5%)>漠甲亚科Pimeliinae 9属12种(18.8%)>朽木甲亚科Alleculinae 3属5种(7.8%)>伪叶甲亚科Lagriinae 3属4种(6.2%)>菌甲亚科Diaperinae 3属3种(4.7%);在区系组成上,河北拟步甲与华北区关系最为密切,共计38属63种(98.4%),其次为蒙新区28属47种(73.4%),其他动物区的成分较少;河北拟步甲在河北昆虫地理区划的分布呈现:山麓平原区30属42种(65.6%)>冀西北间山盆地区24属40种(62.5%)>冀北山区12属14种(21.9%)>坝上高原区11属14种(21.9%)>冀西山区9属10种(15.6%)>低平原区8属9种(14.1%);河北特有种7种,其中6种分布在山麓平原区。The species diversity and distribution characteristics of the darkling beetles from Hebei,China were preliminarily analyzed,based on the data of sixty-four species（ subspecies） belonging to thirty-eight genera,nineteen tribes and five subfamilies distributed in Hebei（ including Beijing and Tianjin）. The results showed that the species with highest diversity was Tenebrioninae（ 40 species,occupying 62. 5% of the total）,followed by Pimeliinae（ 12 species,accounting for 18.8%）,Alleculinae（ 5 species,accounting for 7. 8%）,Lagriinae（ 4 species,accounting for 6. 2%）,and Diaperinae（ 3species,accounting for 4. 7%）. The distributional relations of darkling beetles from Hebei were closest to the North China region（ 63 species,occupying 98. 4% of the total） in the Chinese zoogeographic regions,followed by the Mongolia-Xinjiang region（ 47 species,accounting for 73. 4%）,while the species of the other regions accounted for a small proportion. The diversity of species in Hebei zoogeographic regions from most to least were Piedmont plain region（ 42 species,occupying 65.6% of the total）〉 West-northern Hebei basin region（ 40 species,accounting for 62. 5%）〉 Northern Hebei mountain region（ 14 species,accounting for 21. 9%）〉 Bashang plateau region（ 14 species,accounting for 21. 9%）〉 Western Hebei mountain region（ 10 species,accounting for 15. 6%）〉 Low plain region（ 9 species,accounting for 14. 1%）. There were seven endemic species,of which six distribute in Piedmont plain region.
