ASTRAL species tree, input trees derived from multi-partitioned MrBayes analyses of individual gene trees (i.e. using the 6 character in sets in Fig 2 to inform the partitioning strategy).
Node values indicate support values of MrBayes posterior used as ASTRAL bootstrap replicates, branch colors correspond to species clades. Weevils from top clockwise: Eupholus azureus Macleay, Eupholus schoenherrii schoenherrii (Guérin-Méneville), Celebia arrogans (Boisduval), Rhinoscapha sp. “Large-brown Mt.Wilhelm 2700m”, Gymnopholus (Symbiopholus) acarifer Gressitt, Gymnopholus regalis Gressitt, Eupholus cuvierii (Guérin-Méneville), Rhinoscapha tricolor Faust, Rhinoscapha doriae Pascoe, Gymnopholus nitidus Gressitt & Sedlacek.
Fig 2.
Shows approximate position of character sets used for each locus in PartitionFinder 2 for ASTRAL analyses, overlaid on the frequency of PIS in the final UCE data set.
UCE Core refers to the section of the locus that corresponds to the length of UCE probe. Numbers 1–5 on left of UCE Core correspond to matching characters sets on the right, such that e.g. both sections 5 are the same character set. Character sets 1–5 correspond to one fifth of the length of the locus (left and right of UCE Core) minus the sites from the UCE Core.

Left: Boxplot of number of UCEs by preservation type.
Average number of UCEs for modern ethanol preserved specimens was higher than for museum pinned specimens. Right: Plot of number of UCEs vs their date of collection. Plot shows general trend of fewer UCEs captured for the older the specimens, however the exact rate of decrease would require more specimens systematically sampled by precise preservation type.
Fig 4.
Left: Histogram of the number of potentially informative sites per locus from final data matrices, calculated with pis function it the R library ips.
Right shows linear regression between the number of phylogenetically informative sites and loci length. Loci of shorter length tend to have a narrower range of informative sites whereas longer loci tend to have a wider range, giving the distribution a clubbed appearance.

Phylogenetic tree results of the Eupholini weevils, branch colors correspond to species clades: LEFT: RAxML tree from concatenation of loci.
Dashed lines denote nodes that differ between trees. Node values indicate bootstrap support values. RIGHT: ASTRAL species tree, input trees derived from multi-partitioned MrBayes analyses of individual gene trees. Node values are derived from posterior distribution of MrBayes trees (minus burn-in) where each sample of the MCMC generation represents a bootstrap sample to ASTRAL.

Table 1.
Pairwise comparisons of topological distances between different tree reconstruction methods used.
Tree to tree topological distance metrics used the subtree prune and regraft distance (SPR_DIST), Robinson-Foulds distance (RF_DIST), path distance metric between pairs of taxa (PATH.DIFF_DIST). The ASTRAL trees based on multiple partitions are the ASTRAL RAxML tree using six character-sets (astral_raxmltree), ASTRAL RAxML tree based on single character-sets/partitions (astral_singlepart_raxmltree), ASTRAL MrBayes tree using six character-sets (astral_mrbtree) and ASTRAL MrBayes tree based on single character-sets/partitions (astral_singlepart_mrbtree). Results of lower triangle shown.
Fig 10.
Linear regression of logit proportion of UCE loci captured versus specimen age.
Number of UCE loci and specimen age for; Xylocopa (carpenter bees) from Blaimer et al. 2016, Aphelocoma (scrub-jays) from McCormack et al. 2016, Eupholini (smurf weevils) from this study. Specimen age is in years from when individual was first collected and preserved. Regressions show a decline in the number of UCE loci captured as specimen age increases, the rate of decline is similar between studies.
