Abstract
Bethylidae are found frequently in Cenozoic amber (Azevedo et al., 2018), especially in the lowermost Eocene Oise amber of France, where one species of Bethylinae (Eupsenella eocenica De Ploëg & Nel, 2004), three species of Epyrinae (Elektroepyris magnificus Perrichot & Nel, 2008, Chloromyia gallicus (Perrichot & Nel, 2008), and Epyris moulyi Falières & Nel, 2018), one species of Scleroderminae, and two species of Pristocerinae (Eopristocera bilobata Falières & Nel 2019 and one in the genus Pristocera) (Falières & Nel, 2019a, b) have previously been recorded. Thus the Oise amber fauna confirms that this important hymenopteran family was already well established and diverse in the Paleogene. Here we describe the first representative in this amber of the small extinct subfamily Protopristocerinae, previously known from two genera and species from the Baltic amber, plus an uncertainly assigned genus from the mid-Cretaceous Burmese amber.
