Hymenoptera Chrysidoidea morphological discontinuity geographical disjunction


The Afrotropical pristocerine genus Pristonesia is revised. Seven species are recognized, one previously described species, P. nyamuragira (Benoit), and six species are described and illustrated as new: P. oracil sp. nov., P. parcetil sp. nov., P. querfil sp. nov., P. sicril sp. nov., P. tainatril sp. nov., and P. uvenil sp. nov. A key to the Afrotropical species is presented. Additionally, the main morphological diagnostic characters and the morphological relationships of Pristonesia with other pristocerine genera are discussed. The diagnostic characters are revised, and the genus can be identified by the presence of apical projections on the harpe; a setose apical aedeagal lobe; a predominantly flattened cuspis; and the absence of a cupula on the ventral side of the genitalia.
