Stenoma straminella is a moth in the Depressariidae family. It was described by Walker in 1864. It is found in Brazil (Amazonas). Adults are pale straw-colour, the forewings hardly acute, with four black points. The first point close to the base, the second at one-fourth of the length, the third a little beyond the second and more hindward and the fourth beyond the middle. There is an incomplete outward-curved row of submarginal black points and the exterior border is rather oblique. The hindwings are whitish.
