Wingspan 15–20 mm. The imago is similar to some forms of Celypha lacunana. Orthotaenia undulana shows more discrete markings. It lacks the incision on the basal edge of the central band and the central lacuna. The distal edge of the central band may have a double projection or a single broad one when these are merged.
It may also resemble Celypha cespitana and Celypha rivulana but has no strong markings in the distal third of the wing.
