Distribution

Afrotropical region: Mauritius, Reunion, Tanzania. Introduced to: Indo-Australasian region: China, Guam, Hong Kong, India, Japan, Okinawa, Taiwan, Thailand, Samoa, Singapore. Nearctic region: Hawaii & Florida (USA).

Biology

Gall former on the leaves, petioles and twigs of Coral trees (Erythrina species, Fabaceae). Three described species of Aprostocetus and 3 other described species of Quadrastichus are associated with Erythrina galls (Prinsloo & Kelly 2009). In addition a species of Eurytoma erythrinae is believed to be a parasitoid of the eulophid gall inducers (Gates & Delvare 2008). Aprostocetus exertus and Eurytoma erythrinae have the potential to act as biocontrol agents of the Erythina Gall Wasp which is rapidly spreading around the world (La Salle et al. 2009).
