Eucharitidae (Hymenoptera, Chalcidoidea), a family new to the fauna of Saudi Arabia, with the description of the previously unknown male of Eucharis (Psilogastrellus) affinis Bouček

Abstract

The family Eucharitidae (Hymenoptera: Chalcidoidea) is recorded for the first time for the fauna of Saudi Arabia based on Hydrorhoa caffra (Westwood) and Eucharis (Psilogastrellus) affinis Bouček. The record of H. caffra suggests that Al-Baha and Asir provinces should be considered as part of the Afrotropical rather than the Palaearctic region. The previously unknown male of E. affinis Bouček is described and figured. Macrophotographs of the species are provided.
