Abstract.  A phylogenetic hypothesis for the tribe Ithomiini (Lepidoptera: Nymphalidae: Danainae) is presented, based on sequences of the mitochondrial cytochrome oxidase subunits I and II (COI–COII) region and regions of the nuclear genes wingless and Elongation factor 1-alpha. Branch support for each clade is assessed, and a partition congruence index is used to explore conflict among gene regions. The monophyly of the clade is strongly supported, as are many of the traditionally recognized subtribes and genera. The data imply paraphyly of some genera and tribes, but largely support recent classifications and phylogenetic hypotheses based on morphological characters.
