Ornativalva undella is a moth of the Gelechiidae family. It was described by Sattler in 1976. It is found in south-eastern Iran. The wingspan is about 5 mm. The forewings are dark brown between the costa and the fold and ochreous between the fold and the inner margin. The dividing line between these dark and light areas is W-shaped at the fold. The light area crosses the fold near the middle and extends to the end of the cell. The forewings are ochreous at the apex and along the outer margin and there is a light dot on the costa at two-thirds. Adults have been recorded on wing in May.
