Platyptilia omissalis is a moth of the family Pterophoridae. The species was described by Thomas Bainbrigge Fletcher in 1926. It is found in Australia from southern Queensland to Victoria, south-western Australia and Tasmania.
Some authors consider it a synonym of Sinpunctiptilia emissalis.
Adults have a weak, almost hovering flight.
The larvae feed on the leaves of Parahebe species, including Parahebe perfoliata. At first, feeding results in a blotch mine on the upper surface of the leaf. Later, the larvae feed exposed on the upper surface of the leaf. The pupa is elongate, without a cocoon, and rests (fully exposed) on the vegetation attached to a silk pad by hooks at the rear end.
