Revision of Acroclisoides Girault & Dodd, 1915 (Chalcidoidea, Pteromalidae, Metasteninae)

The species of Acroclisoides Girault & Dodd (Pteromalidae: Metasteninae) are revised. Twenty-three world species are recognized based on females, of which eight new species are described: Acroclisoides bimaculatus Tselikh, sp. nov. (Australia), A. fusus Tselikh & Mitroiu, sp. nov. (Africa), A. marimbae Tselikh & Mitroiu, sp. nov. (Africa), A. miklukhai Tselikh, sp. nov. (Papua New Guinea), A. nongae Tselikh, Lee & Ku, sp. nov. (Eastern Palearctic), A. simbis Tselikh & Mitroiu, sp. nov. (Africa), A. supramaculatus Tselikh, sp. nov. (Australia) and A. suryai Tselikh, sp. nov. (India). The genus Golovissima Dzhanokmen, 1982, syn. nov., is synonymized under Acroclisoides Girault & Dodd, 1915; the species Euneura borocerae Risbec, 1957, previously included in Acroclisoides by Bouček (1976), is transferred to Agiommatus Crawford, 1911, as A. borocerae (Risbec, 1957), comb. nov. The hitherto unknown male of A. major Girault & Dodd, 1915 is described for the first time. The following new records are reported: A. laticeps Girault & Dodd, 1915 from Papua New Guinea; A. luzonensis Gahan, 1920 from Indonesia, Malaysia and Republic of Korea; A. sinicus (Huang & Liao, 1988) from Japan and Vietnam; A. solus Grissell & Smith, 2006 from Japan and Russia. All the species are described or redescribed and illustrated by macrophotography, including type material of previously described species, and a key for the identification of the twenty-three known species is given.
