The tetrastichine wasps (Hymenoptera: Chalcidoidea: Eulophidae) associated with galls on Erythrina species (Fabaceae) in South Africa, with the description of five new species

摘要

Five new tetrastichine eulophid species are described from both sexes from South Africa: Quadrastichus ingens, Q. gallicola and Q. bardus induce leaf, petiole and shoot galls on indigenous Erythrina species (Fabaceae); Aprostocetus nitens and A. tritus are parasitoids of the Quadrastichus species; Q. bardus and A. nitens are also recorded from Tanzania and comments are provided on A. exertus La Salle, known from Tanzania and South Africa as a parasitoid of Q. erythrinae Kim and Q. ingens. A key is provided for the separation of the six eulophid species now known from South Africa.
