Abstract

Gallastichus mutuus Rasplus & La Salle gen. nov. & sp. nov. (Hymenoptera: Chalcidoidea: Eulophidae) and Ormyrus nkoloensis Rasplus sp. nov. (Hymenoptera: Chalcidoidea: Ormyridae) are described from Cameroon. Both taxa were collected from leaf galls formed on Bikinia letestui (Pellegr.) Wieringa subsp. letestui (Fabaceae: Caesalpinioideae). Gallastichus mutuus appears to be responsible for gall induction, whereas O. nkoloensis is likely a secondary coloniser, either a parasitoid or an inquiline. This is the first recorded instance of a gall being induced in an extrafloral nectary.
