Abstract: The study of Japanese encyrtids has been started with desctiption of first new
species by Howard in 1898. Later many authors devoted their attention to the
study of Encyrtidae in Japan. Almost all type specimens of Encyrtidae, described
by Tei Ishii and Tetsusaburo Tachikawa, were examined, and all Encyrtidae
recorded from Japan, which were available in Japanese collections, are revised.
Fifty-two genera and 150 species were recorded to date from Japan. Five new
species are described and illustrated: Aphidencyrtoides tachikawai Japoshvili
sp. nov., Leptomastix teii Japoshvili sp. nov., Psyllaephagus enokicola
Japoshvili sp. nov., P. higashiurai Japoshvili sp. nov. and P. kamitanii
Japoshvili sp. nov. One genus, Parablastothrix Mercet, 1917, and five species,
Adelencyrtus comis (Noyes & Ren, 1987), Anagyrus bicolor Noyes & Hayat,
1994, Leptomastix auraticorpus Girault, 1915, Parablastothrix maritima
Logvinovskaya, 1981, and Syrphophagus aeruginosus (Dalman, 1820), were recorded
for the first time from the country. Nine new synonymies are established:
Aschitus Mercet, 1921, syn. nov. of Microterys Thomson, 1876; Anicetus eous
Trjapitzin, 1965, syn. nov. of A. annulatus Timberlake, 1919; Blastothrix
kermivora Ishii, 1828, syn. nov. of B. erythrostetha (Walker, 1847);
Cerchysiella togashii Tachikawa, 1988, syn. nov. of Bethylomimus academus
Trjapitzin, 1967; Cheiloneurus japonicus Ashmead, 1904, syn. nov. of Ch.
claviger Thomson, 1876; Epitetracnemus Girault, 1915, syn. nov. of Adelencyrtus
Ashmead, 1900; Ericydnus japonicus Tachikawa, 1963, syn. nov. of E. longicornis
(Dalman, 1820); Eugahania mongolica Hoffer, 1970, syn. nov. of E. yanoi
Tachikawa, 1956; Leptomastidea rubra Tachikawa, 1956, syn. nov. of L. bifasciata
(Mayr, 1876). Thirty two new combinations are proposed: Adelencyrtus bandus

Ren, 1987) comb. nov. (from Epitetracnemus), A. intersectus (Fonscolombe, 1832)
