Greenidea psidii
van der Goot, 1917
Greenidea psidii is a of in the , Greenideinae. It was described by van der Goot in 1917 and has been recorded in Brazil, Hawaii, and the continental United States. The species is associated with plants in the Psidium, particularly Psidium guajava (guava) and Psidium cattleianum ( guava). It has been recently detected as a non- species in new geographic regions, raising interest in its potential as an emerging pest.
