Review of the species of the genus Leptomastidea Mercet, 1916 (Hymenoptera, Encyrtidae) of the World, with description of a new species from Montenegro and with separation of a new genus from Turkmenia

The review contains a key to females of the species of the genus Leptomastidea Mercet, 1926 of the World fauna and annotated synopsis of 25 species with data on their distribution, hosts, plants, and use in biological control [for L. abnormis (Girault)]. L. ljubodragi sp. n. is described from Montenegro. A new genus Proleptomastidea gen. n. is erected for Leptanusia enigmatica Trjapitzin, 1971 from Turkmenistan. Leptanusia turkmenica Myartseva, 1978 is transferred to the genus Anagyrus Howard, 1896 and, thus, a new combination, Anagyrus turkmenicus (Myartseva, 1978), comb. n., is formed.
