A molecular phylogeny of the Ctenuchina

The Ctenuchina are a subtribe of tiger moths in the subfamily Arctiinae. Ctenuchina are known for their mimicry of noxious insects and association with toxic host plants. Previous molecular studies on tiger moths have been done to create a comprehensive taxonomy; however, there is a lack of understanding when it comes to the phylogenetic relationships between the Ctenuchina and other Arctiinae generic groups. With this study, I will construct a phylogeny for the Ctenuchina using molecular data from 8 loci for 49 species that span the diversity of the lineage. The resulting phylogeny will provide a robust classification for these moths that will facilitate future studies of their life history. To date, I have completed 60.4% of the sampling necessary to complete this project. The preliminary phylogeny shows evidence for a monophyletic Ctenuchina, with the exception of one sample of Orcynia calcarata (Euchromiina) that may be misplaced due to missing data. There is also support for some monphyletic genera (e.g., Correbidia, Heilura). Within Ctenuchina I found one specific genus, Eucereon, that appears to be polyphyletic and requires revision. The addition of the CO1 locus, as well as the finalization of the other loci, may resolve some of these uncertainties. The final phylogeny will establish monophyly of the Ctenuchina as well as elucidate generic relationships within the lineage.
