Brachyunguis (Andinaphis) paradoxus, new Argentinean subgenus and species are described . The new subgenus and new species are characterized by the absence of marginal papillae, processus terminalis of the antennal segment VI longer than the base of segment, tarsal formula 3.3.3 and its host-plant, Senecio (Asteraceae) . These characters are very atypical among Brachyunguis and even Aphidini. Apterous and alate viviparous females and oviparous females are described. The subgenus and species are keyed in two modified previous keys.
