Filatima nucifer is a moth of the Gelechiidae family. It is found in Mexico (Sonora) and the United States, where it has been recorded from Texas. The wingspan is 15–16 mm. The forewings are whitish cinereous, profusely sprinkled with fuscous, forming a small reduplicated spot on the base of the costa, and a few ill-defined groups, at the base of the cilia, around the apex and termen, otherwise evenly and profusely distributed over the wing-surface. There are three small rust-brown spots, two discal and one plical, the first discal scarcely before the middle, the second at the end of the cell. The plical spot is straight below the first discal. The hindwings are greyish at the base, becoming brownish grey outwardly.
