摘　　要：湖北地区已知蚤类87种,其中属东洋界种类41种,占47.1%;属古北界种类38种,占43.7%,广布两界种类8种,占9.2%.古北界种类中,位于鄂西华中第一高峰的神农架林区发现了37种,其中与古北界青海藏南亚区共有的蚤类达18种,具有明显的古北界特征,呈现"古北界岛屿"现象.分析研究后认为,湖北地区蚤类区系应划归东洋界.东洋界与古北界分界线在秦岭以东,湖北地区的走向,应由陕西丹凤入豫后沿南阳盆地西缘南下入鄂抵武当山向东经桐柏山、大别山向东为妥.In the present paper the writers attempts to deal with the problem of the delimitation of the boundaries of the zoogeographical regions in Hubei on the basis of the Fleas fauna of the provence. Among the 87 species of Fleas listed, 41 species （or 47.1 %） belonged to the species entirely or mainly distributed in the Oriental region, 38 species （or 43.7%） to those entirely or mainly distributed in the Palaearctic region, and 8 species （or 9.2%） to those distributed in both Oriental and Palaearctic regions. The writers suggest that the Fleas fauna of Hubei Province should be included in the Oriental region. Mt. Shennongjia is situated at 3150 meters above sea level in west Hubei province, and 54 species fleas was found these. Among them 37 species （or 68.5%） are entirely or mainly distributed in the Palaeactic rogion. The composition is similar as in Qinghai-south Xizang subdistrict. It shows mt. Shennongjia has significant characterstics of ＂Palaeactic rogion island＂. The boundary line between Palaearctie and Oriental regions in Qinling easten of siphonptera is from Danfeng County of Shanxi to from wst edge of Nanyang basin of Henan to Wudong Mt. of Hubei and extension towards Mt. of Tongbai and Mt. of Dabie.
