ABSTRACT. Taxonomic notes on the Nearctic species of the fairyfly genus Gonatocerus Nees ab Esenbeck, 1834 (Hymenoptera: Mymaridae) are given, including new distribution records. Three new taxa are described: G. (Cosmocomoidea) elizavetae sp.n. (Illinois, USA), G. (Cosmocomoidea) ermi sp.n. (California, USA), and G. (Lymaenon) vladimiri sp.n. (New York, USA). Gonatocerus (Gonatocerus) utahensis Girault, 1917 syn.n. is synonymized under G. (Gonatocerus) californicus Girault, 1911. Four Nearctic species of the subgenus G. (Lymaenon Walker, 1846) are redescribed based on study of their type material. A lectotype is designated for G. pygmaeus Girault, 1911. Identification keys to the described Nearctic species of the subgenera G. (Cosmocomoidea Howard, 1908) and G. (Lymaenon) are provided.
