“…The amber fossil contains both a male and female specimen of Pristocerinae, an occurrence of conspecifics in the subfamily that has only previously been recovered in Pristocera skwarrae, which was never photographed or drawn, and was lost in World War II (see Colombo et al 2021). While the two specimens were not preserved copulating, we have chosen to assign them to the same species as conspecifics.…”

“…There are about 90 flat wasps fossil species described, with the oldest known extinct Bethylidae coming from early Cretaceous amber deposits (Engel et al 2016). However, the greatest number of fossil bethylids comes from the Eocene, specifically Oise, Rovno, and Baltic amber deposits (Colombo et al 2020a(Colombo et al , 2021.…”

“…With over 1,000 species in 26 genera, Pristocerinae are the most speciose subfamily within Bethylidae and are found worldwide (Azevedo et al 2018;Colombo et al 2020aColombo et al , 2021. The subfamily is known for its remarkable sexual dimorphism, with males possessing robust bodies, wings, and conspicuous eyes and ocelli while females are wingless, lack ocelli, and have eyes that are extremely reduced or missing (Alencar et al 2018).…”

“…Of these species, 11 are known from males only, three are known from females only, and only one species, Pristocera skwarrae (Brues), was described from a fossil that contained both a male and female. Additionally, Brues (1933) does not include any illustrations of the species and it was presumed to be lost during World War II (Colombo et al 2021).…”

“…About 50% of extinct Bethylidae come from Baltic amber deposits dated to the late Eocene, including four of the 15 extinct Pristocerinae from the genera Pseudisobrachium Kieffer, Cleistepyris Kieffer, and Pristocera Klug (Colombo and Azevedo 2019;Colombo et al 2021). Here we present a new extinct genus of Pristocerinae from Baltic amber, †Archeonesia Tribull, Pankowski & Colombo, gen. nov. with the type species †A.…”

A new extinct genus and species of Pristocerinae, †Archeonesia eocena Tribull, Pankowski & Colombo, gen. et. sp. nov., are described from upper Eocene Baltic amber from the Yantarny amber mine in the Kaliningrad region, Russia. Descriptions, remarks, illustrations, and comparisons to all extinct and extant Pristocerinae are provided. †Archeonesia is described as a new genus because neither the male nor the female can be placed in any previously described genera, although the female is most similar to Acrenesia and the male is most similar to Cleistepyris. Rare for Bethylidae, and Hymenoptera in general, this fossil contains both a male and female specimen that we are describing as conspecifics. A brief review from the paleoentomological literature is provided to describe how insect fossils containing evidence of reproductive behavior have been used to associate conspecifics in extinct species.
