The variability of Aphis schinifoliae Blanchard, 1939, is discussed and males are described. Apterous and alatae viviparous females, oviparous females, and males of a new species. Aphis schinivora, are described. A key to Aphidini species that could be found on Anacardiaceae in South America is given. Resumen. — Se han estudiado los pulgones recogidos en localidades de Argentina y Chile, principalmente andinas, sobre especies de Schinus (Anacardiaceae). Se expone la variabilidad de Aphis schinifoliae Blanchard, 1939 y se describen los machos. Se describen las hembras viviparas apteras y aladas, las hembras oviparas y los machos de una nueva especie, Aphis schinivora. Se presenta una clave para las especies de Aphidini que pudieran encontrarse en Sudamerica sobre especies de Anacardiaceae.
