【摘要】 通过新疆叶甲的系统调查,区系和地理分布的初步研究查明:1)新疆叶甲已知种类有404种(17亚种),分隶于11亚科78属,其中以隐头叶甲亚科Cryptocephalinae,叶甲亚科Chrysomelinae和跳甲亚科Alticinae的种类最为丰富,分别为87种(7亚种),97种(2亚种)和71;2)区系组成以古北种占绝对优势,有390种(17亚种),占种数的96.5%,非古北种14种,仅占3.5%.在古北种中,中亚细亚种156种,占种类数的38.6%,泛古北种102种,占25.2%及特有种、中央亚细亚种和欧洲—西伯利亚种等多种成分;3)叶甲地理分布区域分化明显,北疆阿尔泰山、伊犁-塔城谷盆地、准噶尔盆地、天山北部山地和准噶尔西部山地种类较多,分别有111、159、151、122和77种;占新疆2/3以上面积的东疆和南疆,种类较少,尤其是昆仑山山地,还不足10种;4)地域分化亦明显表现在区系组成上,阿尔泰山的中亚细亚种只有14种,仅占该地叶甲种数的12.6%,欧洲-西伯利亚种、欧洲—鄂毕种和西伯利亚种3种成分合计为45种,占到40.5%;伊犁-塔城谷(盆)地和准噶尔盆地的上述3种成分分别为22种和21种都仅占所在盆地14%左右,而中亚西亚种前者占到46%,后者占到34%;5)将新疆动物区系分为12个省级地理区划单元,根据叶甲在各区划单元的分布,进行区系相似性系数聚类分析,其结果同我们所作的2亚界、3区、5亚区和12个省级单元的区划基本相吻合。更多还原

【Abstract】 The analyses of the fauna and geographical distribution of Chrysomelidae in Xinjiang shows that: 1) there are 404 known species(including 17 subspecies) leaf beetles recorded in Xinjiang,belonging to 82 genera in 11 subfamilies; among them Cryptocephalinae having 87 species (7 subspecies), Chrysomelinae having 97 species (2 subspecies) and Alticinae 71 species; 2) the fauna component shows that the Palearctic species are great in number (390 species, including 17 subspecies) and is about 96.5% of the total number in Xinjiang and that there are only 14 Non-Palearctic species (about 3.5%). Among Palearctic species, there are 156 Centro-Asiatic species (38.6%), 102 Pan-Palearctic species (25.2%) and others are endemic species, Centre-Centro-Asiatic species and Europe-Sibirica species; 3) the distribution of leaf beetles in Xinjiang shows several distinct characteristics: more species distributed in Altay mountain, Yili-Tacheng Basin, Zhunggar Basin, the north of Tianshan Mountain and the western hill counties of Zhunggar, with 111, 159, 151, 122, 70, 77 species respectively; the eastern and northern regions, occupying more than 2/3 of Xinjiang in land, have less species, especially in Kunlun Mountain (less than 10 species); 4) as to faunal component, Altay Mountain with much more “Eruope-Sibirica" species (45 species, 40.5% of the total number in the region), and Yili-Tacheng Basin and Zhunggar Basin with much more Centro-Asiatic species (69 species in the former, about 46%; and 52 species in the later, about 34%); 5)we divide the fauna in Xinjiang into 12 geographic regions.更多还原
