The evolution of reversed sexual dichromatism and aposematic coloration
have long been of interest to both theoreticians and empiricists. Yet
despite the potential connections between these phenomena, they have
seldom been jointly studied. Large carpenter bees (genus Xylocopa) are a
promising group for such comparative investigations as they are a diverse
clade in which both aposematism and reversed sexual dichromatism can occur
either together or separately. We investigated the evolutionary history of
dichromatism and aposematism and a potential correlation of these traits
with diversification rates within Xylocopa, using a newly-generated
phylogeny for 179 Xylocopa species based on ultraconserved elements
(UCEs). A monochromatic, inconspicuous ancestor is indicated for the
genus, with subsequent convergent evolution of sexual dichromatism and
aposematism in multiple lineages. Aposematism is found to co-vary with
reversed sexual dichromatism in many species; however, reversed
dichromatism also evolved in non-aposematic species. Bayesian Analysis of
Macroevolutionary Models (BAMM) did not show increased diversification in
any specific clade in Xylocopa, whereas support from Hidden State
Speciation and Extinction (HiSSE) models remained inconclusive regarding
an association of increased diversification rates with dichromatism or
aposematism. We discuss the evolution of color patterns and
diversification in Xylocopa by considering potential drivers of
dichromatism and aposematism.
