Revision of the fossil species of Thaumatodryinus Perkins from Dominican amber, with a new combination and description of a new species (Hymenoptera, Dryinidae)

Abstract

The fossil species of Thaumatodryinus from Dominican amber are studied, and the first revision is presented with a key to the known taxa. We recognize three species, T. miocenicus Olmi, 1995, T. priscus (Olmi, 1998), comb. nov. and T. fuscescenssp. nov. The current classification of the genus and relationships between fossil and living species are discussed. Comments on the host records for Thaumatodryinus are presented.

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

“…To date, Bocchus is the most common genus of Dryinidae in Rovno amber fauna and Bocchinae is the dominant subfamily (44.4% of specimens versus 33.3% for Dryinus and Dryininae) at the specimen level. This is unusual, as Dryininae strongly dominate not only in Baltic amber, but also in Kachin (33 Dryininae species according to Olmi et al 2022) and Dominican (ten Dryininae species versus one belonging to Bocchinae; Martins and Melo 2020) ambers, both at the specimen and species levels.…”
