Monophyly of Callimorphini s.s. and placement of the milkweed tussocks was tested using characters derived from adult morphology of 49 ingroup and 42 outgroups species. This study also assessed the utility of adult genitalic character systems for confident resolution of older divergences. The resulting cladistic analysis demonstrated that phylogenetic relationships among closely related genera were recovered. Relationships among major clades remained poorly supported as determined by taxon and character jackknifes. Based on these results a revised concept for Callimorphini is provided and milkweed tussocks are placed in Phaegopterina rev. placement.

520 $a Monophyly of Callimorphini s.s. and placement of the milkweed tussocks was tested using characters derived from adult morphology of 49 ingroup and 42 outgroups species. This study also assessed the utility of adult genitalic character systems for confident resolution of older divergences. The resulting cladistic analysis demonstrated that phylogenetic relationships among closely related genera were recovered. Relationships among major clades remained poorly supported as determined by taxon and character jackknifes. Based on these results a revised concept for Callimorphini is provided and milkweed tussocks are placed in Phaegopterina rev. placement.
520 $a The phylogenetic relationships of the milkweed tussocks were assessed using 88 characters derived from adult morphology. Based on the phylogeny the ancestor of the ingroup clade fed on cardenolide containing plants, possessed well developed tymbals and hence the potential for ultrasound communication, and lacked coremata for dispersing pheromones. The hypothesis that ultrasound first arose as a redundant cue with subsequent loss of male pheromone was not supported. Instead male pheromone courtship was reacquired after ultrasound courtship in two lineages based on the presence of coremata and behavioral data.
520 $a A phylogeny of 20 Utetheisa species was reconstructed using 106 characters from adult morphology. Based on these data Pitasila and Utetheisa are congeneric. The New World species were not recovered as monophyletic; the rattlebox moth U. ornatrix and the Galapagos endemics were embedded in a clade of Old World species. The Galapagos endemics represent 3 separate invasions of the New World, and 3 independent acquisitions of crypsis in the genus.
520 $a Data from mitochondrial DNA supported independent invasions of the New World. Utetheisa ornatrix placed outside of a clade comprised of Utetheisa species endemic to the Galapagos islands. This preliminary study reveals that sufficient information exists (without saturation) to address relationships and that there is incongruence with morphologically defined species limits between U. galapagensis and U. devriesi.
520 $a The effect of missing data on maximum parsimony reconstruction of phylogeny with morphological data was tested by reconstructing the phylogeny in Bayesian framework. Results indicate that the Bayesian topology was more sensitive to missing data. However, support for recovered clades was stronger in the Bayesian topology.
