Tetragma gei is a moth of the Prodoxidae family. It is found in herb-rich steppe and forest openings in Washington, Idaho, Wyoming and South Dakota.

The wingspan is 11–17 mm. Adults are almost entirely pale ochreous or creamy white. Females possess an elongated, telescoping abdomen used to reach in the deeply recessed ovaries of the host plant.

The larvae feed on Geum triflorum. Young larvae feed inside the developing seeds.
