黑龙江省肖叶甲科种类及地理分布

Faunistic and Distribution of Eumolpidae (Coleoptera: Chrysomeloidea) Species in Heilongjiang Province, China

2005年4月—2007年10月对黑龙江省肖叶甲科的种类及地理分布进行了调查,并根据中国动物地理分区方法,将黑龙江省肖叶甲动物地理分为11个省级区划单元;并根据其的分布记录,构成C数据矩阵,采用最大值法进行聚类运算。结果共记录肖叶甲14属57种(亚种),其中包括隐头叶甲亚科34种、锯角叶甲亚科15种、肖叶甲亚科8种,分别占总数的59.6%、26.3%和14.1%。其他两亚科即隐肢叶甲亚科和瘤叶甲亚科在黑龙江省无分布。在区系成分上有3属共9种只在古北区分布,属于古北种;1种为黑龙江省特有种;其他在古北、东洋两区均有分布,属于广布种。统计分析发现本科的大多数种类均分布于该省东南部,气候较温和湿润的区域。其中东南山区,包括牡丹江东部和西部,共有41种,占总数的71.9%;其次是松嫩平原地区22种和兴安岭山区15种,分别占总数的38.6%和26.3%。聚类分析结果与地理区划结果基本吻合,第一组即牡丹江西部省与牡丹江东部省关系最为密切,第二组松江平原省与松嫩北部省关系最近,而西部干旱草原省与其他各省关系最远。

Surveys were conducted to study faunistic and distribution of Eumolpidae species in Heilongjiang Province between April 2005 and October 2007. Fauna of Eumolpidae in Heilongjiang Province were first divided into 11 geographic sub-regions based on the principles of zoogeographic distribution in China and using distribution records of Eumolpidae species in 11 geographic sub-regions, a C matrix was constructed then a clustering analysis maximum value method was used. A total of 57 species （subspecies） belonging to 14 genera were recorded, including, Cryptocephalinae, Clytrinae, and Eumolpinae, 34 species （accounting for 59.6% of the total）, 15 species （26.3%）, and 8 species （14.1%） respectively. Species of Lamprosomatinae and Chlamisinae have not been found in Heilongjiang Province. Only nine species （belonging to three genera） are distributed in the Palearctic Region and one species is endemic to Heilongjiang Province. The others are widely distributed in the Palearctic and Oriental Region. The analysis indicated that 71.9% of the total species （41 species） are distributed in the southeast of the Province, where the climate is warmer and more humid than other regions. Fifteen and 22 species found in Xing＇an Mountain and Songnen Plain, account for 26.3% and 38.6% of the total number of species respectively. The clustering analysis of region similarity of Eumolpidae demonstrated that the closest relationship was between the western and eastern parts of Mudanjiang Region, then Songjiang Plain Region and Northern Songnen Region. The western dry grasslands region had the most alienated relationship with the others.
