Aphis echinaceae, n. sp. is described from specimens collected in Douglas County, Minnesota, on Echinacea angustifolia (DC.). The aphid is illustrated with biometric data for alate and apterous vivipara. Its short cauda and siphunculi, and presence of secondary sensoria on antennal segments III, IV, and V in both morphs makes this Aphis morphologically similar to A. debilicornis (Gillette and Palmer), A. lugentis Williams and A. caliginosa Hottes and Frison, and root feeding aphids of the subgenus Pseudoprotaphis Kadyrbekov and genus Protaphis Börner. A diagnosis is provided.
