Homalaspis plana occurs in the East Pacific from the Galápagos Archipelago to southern Patagonia.[3] There is a single record from the west coast of South Africa, likely resulting from shipping or aquaculture imports.[4]
Homalaspis plana lives in the intertidal zone and down to 272 m (892 ft). It is a commercially valuable species.[3]
