Greenideinae
Greenideinae is a subfamily of aphids (Aphididae) comprising approximately 179 extant species across 18 genera in three tribes: Cervaphidini, Greenideini, and Schoutedeniini. Species are primarily distributed in eastern and southern Asia, with many exhibiting specialized associations with woody host plants, particularly in Fagaceae. The subfamily has been extensively studied for its complex symbiotic relationships with microbial associates, including the primary endosymbiont *Buchnera aphidicola* and diverse secondary symbionts.
