According to the specimens and literature recorded,there are 30 species of 10 genera belonging to 2 tribes of Lixinae from Northeast China described,including 1 new species: Adosomus subgranulosus sp.nov.,1 new record species from China:Adosomus koreanus Voss, 1937,2 new record species from Northeast China.The identification characteristic and the keys of the genera and species are provided.The morphological characteristics of the species are described,and the colour pictures and genitalia of microscopic examination species are accompanying in this study.The third part is conclusion and argumentation.This paper provided the primary base for systematic study of Lixinae of China.Moreover, it is of great importance in guiding the control of agricultral and forestry pests,and protection of biodiversity in Northeast China.All the specimens examined were deposited in the Insect Collection of Northeast Forestry University,China.
