The Oriental and Australasian species of Acmopolynema Ogloblin (Mymaridae) are reviewed; a key to 19 species with known females is given. The genus Baburia Hedquist is synonymized under Acmopolynema and its type species is transferred to Acmopolynema as A. narendrani (Hedquist) comb. n. Ten new species of Acmopolynema are described: A. capeyorki sp. n. (Australia), A. dilemma sp. n. (China), A. garemma sp. n. (Indonesia), A. isaura sp. n. (Indonesia), A. lurindu sp. n. (Nepal), A. neznakomka sp. n. (Papua New Guinea), A. nupta sp. n. (Nepal), A. orchidea sp. n. (Taiwan), A. problema sp. n. (India), and A. shinbana sp. n. (Malaysia). The following new synonymies are proposed: A. maculata Subba Rao and A. nixoni Subba Rao under A. orientale (Narayanan, Subba Rao & Kaur), A. reticoxilla Xu & Lin under A. longicoxillum Xu & Lin, A. himalum Hayat & Anis under A. indochinense (Soyka), and Baburia fasciata Hedquist under A. tachikawai Taguchi. The genera Chaetomymar Ogloblin and Acanthomymar Subba Rao are synonymized under Palaeoneura Waterhouse, which is redescribed along with its type species, P. interrupta Waterhouse (Australia). Ten species of Chaetomymar, 32 Australian species described originally in Polynema Haliday, Polynema nigrum (Subba Rao) (type species of Acanthomymar), and Acmopolynema unimaculatum Hayat & Anis are transferred to Palaeoneura as new combinations. Polynema ara Girault (= P. blackbourni Girault, syn. n. and P. helena Girault, syn. n.) is transferred to Richteria Girault; P. elatum Girault, P. glabricorpus Girault, P. grotiusi Girault, P. lodgei Girault and P. wallacei Girault are transferred to Agalmopolynema Ogloblin, all comb. n. from Polynema. One new genus and one new subgenus are described: Boccacciomymar gen. n., with type species Palaeoneura turneri Waterhouse (Australia) and Prosto, subgen. n. of Boccacciomymar, with type species Polynema victoria Girault (Australia). Polynema schumanni Girault and P. quadripetiolatum Girault are synonymized under Boccacciomymar (B.) turneri (Waterhouse), comb. n. from Palaeoneura. Palaeoneura evanescens Waterhouse is transferred to Boccacciomymar as B. (B.) evanescens (Waterhouse), comb. n.; Polynema aligherini Girault and P. victoria are transferred to Boccacciomymar (Prosto) as, respectively, B. (P.) aligherini (Girault), comb. n. and B. (P.) victoria (Girault), comb. n. Two new species of Boccacciomymar (Boccacciomymar) and four new species of B. (Prosto) are described: B. (B.) conquistador sp. n. (Australia), B. (B.) decameron sp. n. (Australia), B. (P.) maria sp. n. (Australia), B. (P.) nigugu sp. n. (Australia), B. (P.) pobeda sp. n. (New Zealand), and B. (P.) tak sp. n. (New Zealand). A key to the Australian Polynema-group genera of Mymaridae is provided. The Neotropical genus Xenopolynema Ogloblin, stat. rev., with type species X. areolatum Ogloblin stat. rev., is removed from previous synonymy under Polynema, reinstated as a valid genus, and re-diagnosed based on the type specimens from Argentina and new material from Chile; its relationships with Boccacciomymar are discussed.
