Molecular phylogenetics of the moth genus Omiodes Guenée (Crambidae: Spilomelinae), and the origins of the Hawaiian lineage

► The moth genus Omiodes occurs in the Paleotropics, Neotropics, and Hawaii, but its monophyly has been questioned. ► We used sequence data from mitochondrial and nuclear genes to estimate phylogenies for the genus and related genera. ► With the exception of two species, Omiodes from all regions comprised a well-supported monophyletic group. ► Hawaiian Omiodes were monophyletic with a paleotropical origin, but the origin of the genus as a whole was unresolved.
