福建省肖叶甲科属种分布类型与动物地理格局(鞘翅目)

DISTRIBUTION PATTERNS AND ZOOGEOGRAPHY OF EUMOLPIDAE OF FUJIAN PROVINCE, CHINA (COLEOPTERA)

研究福建省肖叶甲科属与种的分布类型、动物地理成分以及该省与其他地区的区系关系，发现该省的肖叶甲科属级单元以南方成分为主，兼有南北广布成分，无典型的北方属；种的分布以亚洲季风区分布型（包括五种亚型）为主（占总数８５．７％），兼有热带亚洲分布型以及少量的亚洲广布和北方型种，福建省特有种占总数１４．３％。从动物地理角度分析，福建省肖叶甲科区系属于东洋界（东洋界成分占９２．５％），而古北界成分和两界共有成分所占比例很小，古北界与东洋界成分在我国东部季风区逐渐过渡并相互渗透。福建与我国云南有６０个共有种，与台湾有４０种，与海南岛有４６种；与日本（２７种共有）及中南半岛（３３种共有）的关系也比较密切，与新疆和西藏几乎没有什么联系（仅各有２个共有种）。

This paper studies the distributional patterns of genera and species of Eumolpid beetles of Fujian Province, China, their zoogeography and the fauna relation to other regions within or around China. Most of the Fujian Eumolpid genera are of southern elements, some of them are widely distributed, but hardly any one can be treated as typical northern genus. Most of the species (85.7%) have a typical distributional pattern that covers the whole or a part of the Monsoon Region of East Asia and can be divided into five different variations. 14.3% of the species are endemic to Fujian Province. Some species distribute widely in tropical Asia(10.5% of the total) or in the whole Asia (only one species). Only 4 species can be categorized to northern elements. According to the zoogeographical analysis, Fujian fauna belongs to the Oriental Realm (92.5% of the species are Oriental elements). Fujian has 60 species in common with Yunnan Province, 40 with Taiwan Is., 46 with Hainan Is., 27 with Japan, and 33 with IndoChina, but only 2 are in common with Xizang (Tibet) and Xinjiang. It is remarkable that there is a gradual transition and strong introgression of the Oriental and Palaearctic elements in East China, which is of great interest to the studies on world biogeography.
