ABSTRACT Members of the Anagrus atomus (L.) (Hymenoptera: Mymaridae) species complex within the atomus species group of the nominate subgenus of Anagrus Haliday are common egg parasitoids of typhlocybine leafhoppers (Hemiptera: Cicadellidae: Typhlocybinae) in grape and other agroecosystems in Europe and North America. Here, all the species in this complex are reassessed using both molecular and morphometric methods. Findings indicate that this complex includes A. erythroneurae S. Trjapitzin and Chiappini syn. n., A. lindberginae Nugnes and Viggiani syn. n., A. nepetellae Viggiani and Nugnes syn. n., A. parvus Soyka syn. n., and A. ustulatus Haliday syn. n., all of which are synonymised with A. (Anagrus) atomus based on the presented genetic evidence. We consider the slight morphological differences among these nominal species to be at most due to intraspecific, rather than interspecific, variability. As such, populations of A. atomus in the New World (the Nearctic region, Argentina, and Chile) and New Zealand, where it is likely not native, appear to be the result of inadvertent spread with agricultural crops and other plants by European settlers.

重新评估 Anagrus atomus 物种复合体（膜翅目：Mymaridae）内的分子和形态变异：欧洲和北美叶蝉（半翅目：Cicadellidae）的卵寄生物

摘要 Anagrus atomus (L.) (膜翅目：Mymaridae) 物种复合体在 Anagrus Haliday 的命名亚属的 atomus 物种组中的成员是葡萄和欧洲其他农业生态系统中 typhlocybine 叶蝉（半翅目：Cicadellidae：Typhlocybinae）的常见卵寄生物和北美。在这里，该复合体中的所有物种都使用分子和形态测量方法重新评估。结果表明，该复合体包括 A. erythroneurae S. Trjapitzin 和 Chiappini syn。n., A. lindberginae Nugnes 和 Viggiani Syn。n., A. nepetellae Viggiani 和 Nugnes syn。n., A. parvus Soyka syn。n. 和 A. ustulatus Haliday Syn。n.，根据所提供的遗传证据，所有这些都与 A. (Anagrus) atomus 同义。我们认为这些名义物种之间的细微形态差异至多是由于种内变异，而不是种间变异。因此，新大陆（近北冰洋地区、阿根廷和智利）和新西兰的 A. atomus 种群似乎不是本地人，似乎是欧洲定居者用农作物和其他植物无意传播的结果.
