Weevils (Curculionoidea) comprise one of the most diverse groups of organisms on 
earth. There is hardly a vascular plant or plant part without its own species of 
weevil feeding on it and weevil species diversity is greater than the number of 
fishes, birds, reptiles, amphibians and mammals combined. Here, we employ 
ultraconserved elements (UCEs) designed for beetles and a novel partitioning 
strategy of loci to help resolve phylogenetic relationships within the radiation 
of Australasian smurf-weevils (Eupholini). Despite being emblematic of the New 
Guinea fauna, no previous phylogenetic studies have been conducted on the 
Eupholini. In addition to a comprehensive collection of fresh specimens, we 
supplement our taxon sampling with museum specimens, and this study is the first 
target enrichment phylogenomic dataset incorporating beetle specimens from 
museum collections. We use both concatenated and species tree analyses to 
examine the relationships and taxonomy of this group. For species tree analyses 
we present a novel partitioning strategy to better model the molecular 
evolutionary process in UCEs. We found that the current taxonomy is problematic, 
largely grouping species on the basis of similar color patterns. Finally, our 
results show that most loci required multiple partitions for nucleotide rate 
substitution, suggesting that single partitions may not be the optimal 
partitioning strategy to accommodate rate heterogeneity for UCE loci.
