Native to Australia. Introduced to Afrotropical region: South Africa; Neotropical region: Argentina; Oriental region: Thailand (Huang et al. 2018).


Parasitoid of Lineage A of the eucalyptus gall wasp Leptocybe invasa, and of Selitrichodes neseri (Tetrastichinae, Eulophidae) and of Megastigmus pretorianensis (Megastigmatidae), all part of the Leptocybe gall associated community on Eucalyptus camaldulensis (Gevers et al. 2020). Originally thought to be a gall-former in seed capsules of Eucalyptus camaldulensis and has also been reared from seed capsules of Syzygium cordatum in South Africa (Grissell, 2006). Reared from Leptocybe invasa galls on Eucalyptus species in Thailand (Doganlar & Hassan, 2010), and South Africa (Gevers et al. 2020). Also a parasitoid in the Quadrastichodella nova gall community on Eucalyptus (Klein et al. 2015).
