Microphotographs were taken of the bodies. Study shows that： Encyrtus sasakii Ishii reproduces annually and overwinters as pupa in their host. Besides the individual differences resulting from development, the 1st and 2nd instar larvae have long breath pedicles in the end of abdomen, and with the larva molting during development, the exuvia accumulate at the end of the body, form a hollow sac called caudal sac that cover the breath pedicle during 3rd and 4th instar larvae. The scutulis of females are yellow, and foreside of wings is light fumed with a dark blotch covered by dense black thick hairs. While the males are black brown, the wing is light in color without a dark blotch.展开更多

Metaphycus liaoi sp. nov. is similar to M. stagnarum. In females of Metaphycus liaoi, the maximum width of antennal scape is located in basal half; ovipositor clearly longer than mid tibia. In males of M. liaoi, F1 is clearly shorter than pedicel; antennal scape clearly flattened and expanded, about 3 x as long as broad. The specimens including the holotype are deposited in Institute of Zoology, Chinese Academy of Sciences, Beijing （IZCAS）.展开更多
