【摘要】 园蛛是农林害虫重要的捕食性天敌,我国已记录41属328种。本文对内蒙古园蛛科(Araneidae)蜘蛛进行了系统的分类研究,包括研究简史、种类、分布、形态特征、外生殖器的比较解剖等。记录了内蒙古园蛛科(Araneidae)蜘蛛共48种,隶属于3亚科15属,其中包括6个新种:类有角园蛛Araneus angulatoides sp. nov.,包头园蛛Araneus baotouensis sp. nov.,蝶斑园蛛Araneus fuscocolorata sp. nov.,拟肥胖园蛛Araneus pseudopinguis sp. nov.,距状肥蛛Larinia calcariformis, sp. nov.和乌氏园蛛Araneus uritai sp. nov. ;一雄性新发现:临沭园蛛Araneus linshuensis Yin et al., 1990。并对国内原记载的个别种进行了修订。区系分析表明,内蒙古的园蛛科蜘蛛主要以古北界种类占绝对优势,仅分布于古北界的种为32种,占总数的66.67%,古北界-东洋界共有种为16种,占总数的33.33%。内蒙古的园蛛科蜘蛛主要归属于我国动物区系中的东北区、华北区、蒙新区三个区,其中分布于东北区的种类最多,为13种,占27.08% ,仅有少量华北区(2种占4.17%)和蒙新区(3种占6.25%)的成分;蒙新区东部草原亚区种类丰富,占蒙新区种类总数的92.85%。更多还原

【Abstract】 In this paper, the author has collected and identified 48 species belonging to 3 subfamily 15 genus of the Family Araneidae from Inner Mongolia, China. Of which, 6 species are new to science, named Araneus angulatoides sp. nov.,Araneus baotouensis sp. nov., Araneus fuscocolorata sp. nov.,Araneus pseudopinguis sp.nov.,Larinia calcariformis, sp. nov. and Araneus uritai sp. nov. ;one male new recovery:Araneus linshuensis Yin et al., 1990.; 2 species is reviewed. An analysis of the species of Araneidae composition in this area and a comparison of the spider faunas between Inner Mongolia and its adjacent provinces and country are made in the paper as well. The distribution and ecology of the spiders are discussed with related to the characters of the geography. Based on a analysis of all the species and their distribution, the more species from Inner Mongolia are palaearctic realm of origin (66.67% of all). There is 16 species (33.33%of all) are palaearctic realm and oriental realm of origin. 13 species (27.08% of all) collected from the North-east China region; 3 species (6.25%of all) collected from Meng-Xinjiang region, 2 species (4.17%of all) collected from Hua-Bei region.
