Abstract: We report the rediscovery of the holotype of Pristocera masii Soika, 1933
(Hymenoptera: Bethylidae: Pristocerinae), originally described from a single
male from Venice, Italy. The holotype was considered lost but during a
scientific visit at the Museo Civico di Storia Naturale “Giacomo Doria” in
Genova, Italy we were able to find the holotype. Here we provide a detailed
redescription, with photographs and drawings of the main diagnostic characters
delimiting this species. Pristocera masii is transferred into Acrepyris Kieffer,
1905 because its hypopygium is simple, not deeply divided as in Pristocera
Klug, 1808, and its aedeagus has three distinct valvae, a remarkable and
exclusive feature of Acrepyris. The resulting new combination, Acrepyris masii
(Soika, 1933), is established here.
