Apiomorpha is a genus of scale insect that induces galls on species of Eucalyptus. Galls are initiated by first-instar nymphs (crawlers) on new plant growth and, when mature, the galls exhibit marked sexual dimorphism. Those induced by females are among the largest and most spectacular of arthropod-induced galls whereas those of males are small and most are tubular. Apiomorpha is known only from Australia and New Guinea although its host, Eucalyptus, has a wider distribution into Indonesia as well. Apiomorpha is currently classified in the Eriococcidae, but this family is not monophyletic.
