Imma tetrascia is a moth in the family Immidae. It was described by Edward Meyrick in 1912. It is found in Australia, where it has been recorded from Queensland[1] and Western Australia.[2]
The wingspan is 19–20 mm. The forewings are pale ochreous yellowish with four rather irregular transverse fuscous lines or shades, the first very near the base, the second at one-third, broken and interrupted in the middle, the upper portion oblique, the third beyond the middle, somewhat oblique, the fourth from four-fifths of the costa to the tornus, rather curved, sometimes very faint except towards the costa. There is a slender dark fuscous streak around the apex and upper portion of the termen. The hindwings are rather dark fuscous.[3]
