Molecular and morphological data indicate that the pest thrips damaging M yoporum species in C alifornia and H awai'i, K lambothrips myopori M ound and M orris, originated in T asmania, A ustralia. This trans‐ P acific dispersal presumably resulted from the international horticultural trade in M yoporum species. The data distinguish the pest from K . adelaideae sp.n. that induces leaf deformation on M . insulare along the coast of mainland A ustralia that is separated by ∼300 km from T asmania by the B ass S trait. K . myopori is more damaging to its non‐native hosts in C alifornia and H awai'i than to M . insulare in T asmania, and further research is needed to determine if this is the result of release from its natural enemies. However, in certain areas of C alifornia, some M yoporum species are invasive weeds, and K . myopori may be considered an example of an accidental but beneficial introduction in this instance because of its detrimental impact on the plant species.
