New species of Hymenoptera associated with galls on Calliandra brevipes Benth. (Fabaceae, Mimosoidea) in Brazil

Four species of Hymenoptera: Tanaostigmodes ringueleti (Brèthes, 1924), T. mecanga sp.nov. (Chalcidoidea, Tanaostigmatidae), Allorhogas taua sp. nov. (Braconidae, Doryctinae) and Eurytoma sp. (Chalcidoidea, Eurytomidae) were reared from two different types of galls of Calliandra brevipes Benth. (Fabaceae, Mimosoidea) in Juiz-de-Fora, Minas Gerais State, Brazil. The two Tanaostigmatidae species are probably the gall inducers; the Braconidae species probably is phytophagous inquiline in round gall type. The two new species are described and illustrated, including their immature stages.
