The recently re-discovered, unique amber named ajkaite, coming from the Late Cretaceous (Santonian) Ajka Coal Formation is an unexpectedly rich source of arthropod inclusions. The present paper describes three new species of wasps from ajkaite, namely Ajkanesia harmincipsziloni Szabó & Brazidec gen. et sp. nov. (Bethylidae: Pristocerinae), Amissidigitus belae Szabó & Brazidec gen. et sp. nov. (Bethylidae: Scleroderminae) and Spathiopteryx soosi Szabó, Brazidec & Perrichot sp. nov. (Spathiopterygidae). Hymenopterans were already reported from the Miocene and Pliocene of Hungary as adpression fossils, but these have only remained identified at higher taxonomical rank. Therefore, the three new ajkaite taxa are the first formally described fossil hymenopteran species from Hungary. The three ajkaite wasps greatly improve our knowledge on the Cretaceous fossil record of their respective (sub)families, which is otherwise very poorly documented. The suggested paleoenvironmental preferences of the new hymenopteran taxa accord with the forested, swampy to lacustrine ecosystem, in which the Ajka Coal has been deposited. Further ajkaite hymenopterans are likely to be stored in Hungarian museum collections.

最近重新发现的独特琥珀名为 ajkaite，来自晚白垩纪（桑托尼纪）Ajka 煤层，是节肢动物内含物的丰富来源。本论文描述了来自 ajkaite 的三种新黄蜂，即Ajkanesiaharmincipsziloni Szabó 和 Brazidec gen。等人。十一月 （Bethylidae：Pristocerinae），Amissidigitus bela e Szabó & Brazidec gen。等人。十一月 (Bethylidae: Scleroderminae) 和Spathiopteryx soosiSzabó、Brazidec 和 Perrichot sp。十一月 (Spathiopterygidae)。在匈牙利的中新世和上新世，膜翅目昆虫已经被报道为压迫化石，但这些仅在更高的分类等级上被确定。因此，三个新的 ajkaite 类群是第一个正式描述的匈牙利膜翅目昆虫化石。三只阿杰凯特黄蜂极大地提高了我们对它们各自（子）科白垩纪化石记录的认识，否则这些记录非常少。膜翅目新分类群的建议古环境偏好与 Ajka 煤沉积的森林、沼泽到湖泊生态系统相一致。更多的 ajkaite 膜翅目昆虫很可能被存放在匈牙利博物馆的藏品中。
