Don in Cusco (Peru) and Neophyllaphis iuiuyensis Mier Durante & Ortego sp. nov. collected on Podocarpus parlatorei Pilg. in San Salvador de Jujuy (Argentina). The apterous and alate viviparous females of N. cuschensis and the apterous and alate viviparous females, as well as the oviparous females and males of N. iuiuyensis are described. The differences between the nominotypical subgenus and Chileaphis and also the differences among the 4 species of subgenus Chileaphis, viz. the 2 new species and those already known and found in Chile, N. michelbacheri Essig and N. podocarpini Carrillo are outlined.
