Early 21st-century reclassifications substantially rearranged the families within Aphidoidea: some old families were reduced to subfamily rank (e.g., Eriosomatidae), and many old subfamilies were elevated to family rank.
As reclasificacións de principios do século XXI fixeron rearranxos significativos nas familias incluídas en Aphidoidea: algunhas vellas familias foron reducidas á categoría de subfamilias (por exemplo, Eriosomatidae), e moitas vellas subfamilias foron elevadas a familias.
