Can DNA sequences from one hundred genes resolve Euwallacea phylogeny?

Euwallacea ambrosia beetle species (Curculionidae: Scolytinae: Xyleborini) are native to tropical and subtropical regions of the world and include invasive species in temperate regions. Given their propensity for colonization, Euwallacea species are established in many forested regions throughout the tropics and subtropics having arrived naturally or through human activities. The taxonomy of Euwallacea species is in great need of revision. The most complete species-level molecular phylogeny shows that several species are not monophyletic. The intraspecific morphology of each species is very similar suggesting the existence of cryptic species. In addition, new species with obvious morphological differences have been recently described and more await description. Our preliminary data suggests that ~100% more species are undescribed. In this study, we reconstruct a phylogeny for Euwallacea morphospecies so to guide the revision of the genus. In order to maximize the number of Euwallacea morphospecies and the number of genes, we employed next generation hybrid capture DNA sequencing methodology. We generated DNA data for 100 genes for 100 morphospecies including decades old museum specimens. Details of the phylogenetic results are forthcoming.
