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.
