The present paper describes 1 new species, Coccygidium absolutus Chen & Yang. Coccygidium nihonense Sharkey is recorded for the first time from China. A key to 6 Chinese species of genus Coccygidium Saussure is also provided. All type specimens are deposited in the Beneficial Insects Laboratory, Department of Plant Protection, Fujian Agricultural University, Fuzhou, Fujian. 1. Coccygidium nihonense Sharkey, rec. nov.

Wuyi, Fujian Prov., 1981-07-31, Huang Juchang. Distribution: China (Mt. Wuyi, Fujian; Qingliu, Fujian); Japan. 2. Coccygidium absolutus Chen & Yang, sp. nov.
