Introduction
The pteromalid genus Acroclisoides (type species Acroclisoides megacephalus Girault & Dodd, 1915) belongs to the family Pteromalidae, subfamily Metasteninae (Burks et al. 2022). We are using Metasteninae Ashmead, 1904 instead of Pachyneurinae Ashmead, 1904, as the latter name is a junior homonym of Pachyneurinae Schiner, 1864 (Diptera). Up to now, it comprised 15 species worldwide (UCD Community 2025). Three of the known species, Acroclisoides africanus Ferrière, 1940, A. borocerae (Risbec, 1957) and A. spilopterus (Masi, 1917), inhabit the Afrotropical region. Four species, Acroclisoides laticeps Girault & Dodd, 1915, A. major Girault & Dodd, 1915, A. megacephalus Girault & Dodd, 1915 and A. tectacorisi (Girault, 1924), are distributed in the Australian region. Six other species, Acroclisoides indicus Ferrière, 1931, A. luzonensis Gahan, 1920, A. maculatus Sureshan & Narendran, 2002, A. quintus Xiao & Huang, 2000, A. sativus Kumar & Khan, 2012 and A. sinicus (Huang & Liao, 1988), are distributed in the Oriental region. Three species, Acroclisoides bicolor Luo & Qin, 1991, A. emeljanovi Dzhanokmen, 1982 and A. sinicus (Huang & Liao, 1988), are known from Palearctic region. Euneura borocerae Risbec, 1957 was transferred to Acroclisoides by Bouček (1976), but the examination of the type specimens in MNHN showed that the species in fact belongs to Agiommatus Crawford, 1911 as Agiommatus borocerae (Risbec, 1957), comb. nov.
The biology of most Acroclisoides species is known: they are egg parasitoids of hemipteran genera of the family Pentatomidae: Agonoscelis Spinola, 1837, Antestiopsis Leston, 1952, Atelocera Laporte, 1832, Axiagastus Dallas, 1851, Bathycoelia Amyot & Serville, 1843, Biprorulus Breddin, 1900, Erthesina Spinola, 1837, Halyomorpha Mayr, 1864, Nezara Amyot & Serville, 1843, Oechalia Stål, 1862, Placosternum Amyot & Serville, 1843, Plautia Stål, 1864 (Thompson 1958; Herting 1971; Thirumalai and Ananthakrishnan 1977; Luo and Qin 1991; Clarke and Seymour 1992; Coombs and Khan 1998; Field et al. 1998; Xiao and Huang 2000; Grissell and Smith 2006; UCD Community 2025) and of the family Acanthosomatidae: Acanthosoma Curtis, 1824 (Dzhanokmen 1982). Also, Acroclisoides includes species that are apparently facultative or obligate hyperparasitoids of scelionids of the genera Aphanurus Looss, 1907, Asolcus Miyake, 1900, Telenomus Haliday, 1833 and Trissolcus Ashmead, 1893 (Baltazar 1966; Grissell and Smith 2006; Sabbatini et al. 2019; UCD Community 2025) and also of eupelmids of the genus Anastatus Motschulsky, 1859 (Grissell and Smith 2006; Sabbatini et al. 2019; UCD Community 2025).
This paper revises and keys the known species of Acroclisoides based on examination of all available material including types, redescribes the previously included species, describes new Afrotropical, Australian, Oriental and Palearctic species, illustrates all the species through macrophotography, and provides new host and distribution records.
Materials and methods
The specimens examined in this study are deposited in the collections of the National Institute of Biological Resources (Incheon, Republic of Korea; NIBR), the Science Museum of Natural Enemies (Geochang, Republic of Korea; SMNE), G.B.Pant University of Agriculture & Technology (Pantnagar, India; BUAT), the Zoological Institute of the Russian Academy of Sciences (St Petersburg, Russia; ZISP), the Natural History Museum (London, United Kingdom; NHMUK), the Muséum National d’Histoire Naturelle (Paris, France; MNHN), the University of California (Riverside, USA; UCR); the Canadian National Collection of Insects, Arachnids and Nematodes (Ottawa, Canada; CNC), the Institute of Zoology of the Chinese Academy of Sciences (Beijing, China; IZAS), the Queensland Museum (Brisbane, Australia: QMBA), the National Museum of Natural History, Smithsonian Institution (Washington D.C., USA; USNM), Muséum national d’histoire naturelle (Paris, France; MNHN), Centre de Biologie pour la Gestion des Populations (Montpellier, France; CBGP), Musée royal de l’Afrique centrale / Koninklijk Museum voor Midden-Afrika (Tervuren, Belgium; MRAC), and the Mitroiu Collection (Iași, Romania; MICO).
Morphological terminology, including sculpture and wing venation, follows Bouček and Rasplus (1991), Gibson (1997), and Burks et al. (2022). The flagellum consists of two anelli, six funicular segments, and the four-segmented clava. The antennal formula includes the number of segments: scape, pedicel, anelli, funicular segments, claval segments. The mandibular formula indicates the number of teeth in the left and right mandibles. The following abbreviations are used: POL – posterior ocellar line, the minimum distance between the posterior ocelli; OOL – ocello–ocular line, the minimum distance between a posterior ocellus and compound eye; C1–C4 – claval segments; M – marginal vein; S – stigmal vein; PM – postmarginal vein; F1–F6 – funicular segments; Mt2–Mt8 – metasomal tergites. The scape is measured without the radicle; the pedicel is measured in lateral view. The distance between the clypeal lower margin and the toruli is measured from the lower margins of the toruli. The distance between the toruli and the median ocellus is measured from the lower margins of the toruli to the lower margin of the median ocellus. Eye height is measured as the maximum diameter, eye length as the minimum diameter. The mesosoma and metasoma are measured in lateral view, the latter including the ovipositor sheaths.

Comments.
Acroclisoides bicolor Luo & Qin belongs to a group of species where both sexes have a hyaline fore wing. This species is very similar to A. marimbae Tselikh & Mitroiu, sp. nov.; the differences between these species are given in the key. It is also similar to A. sinicus (Huang & Liao) and A. solus Grissel & Smith, from which it differs in having the fore wing hyaline (although some female specimens of A. solus may also have hyaline wings, see the comments under A. solus) and the posterior corner of gena rounded.
Material from China was misidentified as A. indicus Ferrière. Here this material is regarded as A. bicolor Luo & Qin, 1991.

Comments.
It is important to note that the material from Ghana was misidentified as A. africanus Ferrière by D.S. Hill. Here this material is regarded as A. fusus Tselikh & Mitroiu, sp. nov., because it can be distinguished from A. africanus by the fore wing with one spot near S (vs hyaline); propodeum with median carina and large and smooth nucha (vs propodeum without median carina and with small, alutaceous nucha); lower margin of clypeus in middle part arched and emarginate (vs arched and straight).

Comments.
Acroclisoides solus Grissell & Smith was synonymized with A. sinicus (Huang & Liao) by Sabbatini Peverieri et al. (2019), based on morphological and molecular evidence. However, after examining many additional specimens (see above), we noticed that with a few exceptions they can be grouped in two morphs based on the characters mentioned in the key. Moreover, no type specimen of A. sinicus was sequenced in the mentioned study, so based on these findings we prefer to treat these specimens as two different species until further evidence proves otherwise. The specimens listed in Sabbatini Peverieri et al. (2019) and deposited in MICO, not repeated here, should be treated as A. solus, except the following one that probably belongs to A. sinicus: “1♀ S. Korea: Chungbuk, Okcheon-gun, Bougimyeon, Soesan-li, 150 m, Malaise trap, 10.ix–03.x.2004, 36°16.594'N, 127°36.742'E, Tripotin rec. (MICO)”. The species was introduced both in Europe and North America from Asia, but its exact origin is still unknown. Acroclisoides solus belongs to a group of species where females have a fore wing with one spot near S However, two females from South Korea listed in Sabbatini Peverieri et al. (2019) had hyaline fore wings even if they were genetically very close to the spotted females. Thus they run to A. bicolor in the present key; nevertheless they should be regarded as exceptions and can be separated from A. bicolor by the shape of gena (with a distinct spine in A. solus and without in A. bicolor).
