Abstract: In the present paper,the writers attempt to deal with the problem of the delimitation of the boundaries of zoogeographical regions in Hubei on the basis of the mosquitoes fauna of the province.Among the 11 genera and 72 species of mosquitoes listed,53 species (or 73.6%) belong to the species entirely or mainly distributed in the oriental region, 11 species (or 15.3%) to those entirely or mainly distributed in the palaearctic region, and 8 species (or 11.1%) to those distributed in both oriental and palaearctic region.Basing on the comparison of the mosquito fauna of the adjacent provinces, including Hunan, Jianxi and Henan, the writers suggests that Hubei province should be included in the oriental region but the North-Western part, lying north of 32° N latitude of the province be included in the palaearctic region.
