Se describen dos especies de Uroleucon (Hem. Aphididae, Aphidinae, Macrosiphini) a partir de especímenes colectados sobre compuestas indígenas sudamericanas en la región de Aysén del General Carlos Ibáñez del Campo (Chile), la cual está situada entre los paralelos 43º 38’ 22” S y 49º 09’ 50” S. Uroleucon chiliotrichi sp. n. se describe a partir de hembras vivíparas ápteras recogidas sobre Chiliotrichum diffusum. Uroleucon amigoi sp. n. se describe a partir de hembras vivíparas ápteras y aladas y de hembras ovíparas recogidas sobre Adenocaulon chilense. Se exponen las diferencias de ambas nuevas especies con las especies sudamericanas de Uroleucon más parecidas a ellas.
