The types of Aphis mali var. fulviventris, var. nigricollis, var. nigriventris, var. obsoleta, var. pallidicornis, var. tergata, var. thoracica, and var. triseriata (all Fitch 1855) were rediscovered in the aphid collection of the United States of America National Museum of Natural History. Previously considered nomina dubia, we here establish them, along with Fitch's other two A. mali varieties, var. bivincta and var. immaculata, as junior synonyms of Rhopalosiphum oxyacanthae (Schrank) [=R. insertum (Walker)].
