The Achilixiidae are a family of Fulgoromorpha (planthoppers); species may be found in the neotropical and Asian regions. They are closely related to Achilidae and are sometimes included under Achilidae as a subfamily. Like Achilidae, species generally feed on several species of plant though the nymph stage has been found to feed on fungus. Like other planthoppers, the immature stage is covered in a wax which may help protect it from predators. Achilixiidae are small or medium sized for planthoppers and are greatly compressed, not depressed like the Achilidae.
