Abstract
Encyrtidae is a large family of parasitic wasps, containing some 5,100 described extant species (Noyes, 2023). Five monotypic genera of the earliest fossil Encyrtidae are known from middle Eocene Sakhalinian amber (~45 Ма) (Simutnik, 2014, 2020; Simutnik et al., 2021). Some 20 species in 18 extinct genera of Encyrtidae have been described from late Eocene (~35 Ma) Baltic, Danish, and Rovno ambers (summarized in Simutnik et al., 2023). Several undescribed encyrtids were reported by Noyes & Hayat (1994) and Manukyan (1999) from Baltic amber. One more monotypic genus was described from amber found in Lower Lusatia (Germany), which is probably also dated to the late Eocene (Simutnik et al., 2025). In addition, one species is known from a late Oligocene (23–24 Ma) compression fossil from Rott, Germany (Statz, 1938), and two more species from two extant genera are described from early-middle Miocene (15–20 Ma) Dominican amber (Zuparko & Trjapitzin, 2014; Poinar, 2020).
