A review of Japanese Encyrtidae (Hymenoptera), with descriptions of new species, new records and comments on the types described by Japanese authors

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).
