湖北地区有瓣蝇类分布及地理区划研究

STUDY ON THE DELIMITATION OF ZOOGEOGRAPHICAL REGIONS IN HUBEI, ON THE BASIS OF CALYPTRATAE FAUNA

湖北地区已发现有瓣蝇类 2 80种 ,其中属于东洋界种类 112种 ,占 4 0 0 % ;属于古北界种类 12 8种 ,占 4 5 7% ;广布两界种类 4 0种 ,占 14 3%。经与邻近的江西、湖南和河南蝇类分布种比较研究后认为 ,湖北地区有瓣蝇类区系基本应划归东洋界。

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 calyptratae fauna of the province. Among the 280 species of calyptratae listed, 112 species (or 40 0%) belong to the species entirely or mainly distributed in the oriental region, 128 species (or 45 7%) to those entirely or mainly distributed in the palaearctc region, and 40 species (or 14 3%) to those distributed in both oriental and palaearctic region. Basing on the comparison with the calyptratae fauna of the adjiacent provinces, including Hunan, Jianxi and Henan, the writers suggest that Hubei Province should be included in the oriental region.
