Abstract
The species of Encarsia Förster (Hymenoptera: Aphelinidae) known from China are revised. This study is based largely on newly-collected material from Fujian and Guangdong provinces in mainland China, and from the island of Taiwan. A total of 76 species are treated, including 29 new species, one new combination and 16 new records for China. All species are fully described or diagnosed, and illustrated. Three new specific synonymies are proposed and two lectotypes are designated. Four species are described from males only, three belonging to the perflava-group (ancistrocera, echinocera, viggianii), having modified antennae, and one (magnivena) in the strenua-group having very unusual fore wings. A key to the Chinese species of Encarsia, based largely on females, is provided.
