Etymology. Named after its host plants Astronium and Myracrodruon, whose Brazilian common name is ‘aroeira’. Distribution. Brazil (Distrito Federal, Goiás, Mato Grosso do Sul, Minas Gerais, São Paulo). Host plants. Astronium fraxinifolium Schott, A. graveolens Jacq., Myracrodruon urundeuva Allemão (Anacardiaceae). Some adults were collected on Schinopsis brasiliensis Engl. (Anacardiaceae) which is a likely host. The immatures induce irregular leaf roll galls.
