Lasiomorpha noakesi is a moth in the Eupterotidae family. It was described by Joicey and Talbot in 1917. It is found in New Guinea. The length of the forewings is about 38 mm. The ground-colour of the wings is deep purplish-brown, heavily scaled and covered with short hairs at the base. The forewings have a large hyaline patch without scales below, but is sprinkled with scales of the ground-colour above. The patch is traversed by a dark line parallel to its outer edge which separates a narrow border more thickly scaled than the larger proximal part. There is a small tuft of yellow hair on the middle discocellular. The hindwings are without markings.
