A new species of Bocchus from upper Eocene Rovno amber (Hymenoptera, Dryinidae)

Abstract

A new fossil species of Dryinidae (Hymenoptera, Chrysidoidea) from upper Eocene Rovno amber (Ukraine) is described: Bocchus rexsp. nov. It is compared with two other species of Bocchus known from European amber: B. primaevus Martins & Melo from Baltic amber and B. schmalhauseni Perkovsky, Olmi, Vasilenko, Capradossi & Guglielmino from Rovno amber. A new key to the Cretaceous and Paleogene species of Bocchus is presented. The Dryininae are the most common representatives in all the amber dryinid faunas since the mid-Cretaceous. The Rovno amber fauna is an exception; possible explanations for the abundance of Bocchus species within this amber are presented.

Unexpected Diversity of Xenoscelinae in Priabonian European Amber: The Third Xenosceline Species from Rovno Amber

“…It appears highly likely that the comparatively warmer climate of the Rovno amber forest [ 67 ] was more favourable to xenoscelines and many other thermophile forms [ 53 ] and references therein than the Baltic one, and this is the reason for their comparatively high diversity in the Rovno coleopterofauna [ 37 , 38 , 42 , 45 , 52 , 53 , 57 , 59 , 68 , 69 , 70 ].…”

A review of the biology of the pincer wasps (Hymenoptera: Dryinidae)

“…Eighty-three fossil species of Dryinidae have been described (Olmi et al 2020;Olmi, Eggs, et al 2022).…”

“…Dryinids evolved at least 129 Mya during the Lower Cretaceous (Martynova et al 2019; Olmi et al 2010, 2020; Perkosky et al 2019). Eighty‐three fossil species of Dryinidae have been described (Olmi et al 2020; Olmi, Eggs, et al 2022).…”
