Metallarcha achoeusalis is a moth in the Crambidae family. It was described by Walker in 1859. It is found in Australia.
The markings of the forewings are similar to Metallarcha eurychrysa, but the pale yellow is replaced by deep orange. The hindwings are deep orange, with a dark fuscous hindmarginal band.
