Cerocephalinae (Chalcidoidea, Pteromalidae) is a small group of parasitoid wasps characterized by a number of derived diagnostic features. Their hosts are endophytic beetles. So far, 43 species of Cerocephalinae have been described, including one fossil species from the Miocene. In this study, we add two new genera and species from Baltic and Dominican amber to the fossil record. Tenuicornus dominicus gen. et sp. n. is the second genus described from Dominican amber, and Pteropilosa lailarabanorum gen. et sp. n., described from Baltic amber, represents the oldest record of the subfamily, pushing the minimum age of Cerocephalinae back to the Eocene. Diagnostic characters of both species are discussed in comparison with other Cerocephalinae. An updated key to extant and fossil Cerocephalinae is presented.
头角小蜂亚科（小蜂总科，金小蜂科）是一小群寄生蜂，具有许多特化的鉴别特征。它们的寄主是内生甲虫。到目前为止，已描述了43种头角小蜂亚科物种，包括一种来自中新世的化石物种。在本研究中，我们将来自波罗的海和多米尼加琥珀的两个新属和新物种加入化石记录。多米尼加细角小蜂属及种（Tenuicornus dominicus gen. et sp. n.）是第二个从多米尼加琥珀中描述的属，而从波罗的海琥珀中描述的拉伊拉巴拉诺姆翼毛小蜂属及种（Pteropilosa lailarabanorum gen. et sp. n.）代表了该亚科最古老的记录，将头角小蜂亚科的最小年龄推回到始新世。与其他头角小蜂亚科相比，讨论了这两个物种的鉴别特征。给出了现存和化石头角小蜂亚科的最新检索表。
