Aristotelia argentifera is a moth of the Gelechiidae family. It was described by Busck in 1903. It is found in North America, where it has been recorded from California and western Nevada. The wingspan is 10.5-11.5 mm. The forewings are clear, deep brown, overlaid on the costal half with dark, blackish brown. From near base of the costa is an outwardly directed oblique white fascia, reaching nearly to the dorsal margin, and edged and continued by strongly metallic silvery and bluish iridescent scales. At the middle of the wing is a costal white dash, continued downward and slightly inward nearly to the dorsal edge by a fascia of metallic scales. At the beginning of the costal cilia is a similar larger white dash, continued obliquely inward and downward by a line of metallic scales. Between
