【摘要】 作者在2007—2008年对京津冀地区进行了5次叶蜂区系调查。根据野外采集标本和中南林业科技大学昆虫模式标本室馆藏标本,经鉴定该地区共有叶蜂10科101属317种(包括亚种)。其中包括:62个科学上尚未记载的新物种、5个中国新纪录种和104个河北新纪录种(含4个北京新纪录种与1个天津新纪录种)。另外,作者对该地区的叶蜂区系成分进行了初步分析。结果表明:京津冀地区叶蜂区系成分划分为全北广布成分、古北广布成分和东亚成分等3个区系成分类型,东亚成分是京津冀地区叶蜂区系成分组成的主体,中国特有种在东亚成分中占多数。建议将京津冀地区划分为3个生物地理小区,即:冀东南平原区、冀西北山地丘陵区和张北坝上高原区;京津冀地区叶蜂种类存在4种地理分布类型,即:冀东南平原分布型、张北坝上高原分布型、冀西北山地丘陵分布型和张北坝上高原-冀西北山地丘陵分布型。更多还原

【Abstract】 The sawfly fauna in the district of Beijing,Tianjin and Hebei Province(DBTH) from China was analyzed based on the data of 5 investigations performed from May 2007 to July 2008 by the author and the specimens deposited in the Insect Collection of Central South University of Forestry and Technology.Totally 317 sawfly species including subspecies belong to 10 families,10 subfamilies and 101 genera are recorded from the region.Among them,62 species are undescribed sawfly species.Five species are new records to China,and 104 species are new records to Hebei,4 species are new record to Beijing and 1 species is new record to Tianjin City.In addition,the faunal elements in DBTH sawfly fauna are primarily analysed.The results show that it contains 3 patterns of faunal elements in DBTH,those are Holarctic,Palaearctic and Eastern Asia faunal elements.The endemic elements to China are the core of Eastern Asia elements.The sawfly distribution in DBTH is divided into 3 biogeography districts: Southeast plain of Hebei,Northwest hill district of Hebei and Zhangbei highland district of Hebei.The sawfly species of DBTH are divided into 4 patterns of geography distribution:Southeast plain distribution of Hebei,Zhangbei highland distribution of Hebei,Northwest hill distribution of Hebei,Zhangbei highland - Northwestern hill of Hebei distribution.更多还原
