Davis & Pellmyr, 1992
Greya suffusca is a small prodoxid described in 1992, known only from a restricted area in the Sierra Nevada of California. The is associated with oak and mixed oak-conifer forests, where its larvae develop as seed on the herbaceous plant Osmorhiza brachypoda. It represents one of several narrow-range Greya species with specialized associations.
