  • Likelihood scores (ln L) were estimated using a heuristic search (TBR branch swapping, 10 random addition replicates). Underlining indicates topology with greatest likelihood. The constraint trees are also the species toplogies used in the minimize-deep-coalescences (Maddison and Knowles 2006) and COAL analyses (Degnan and Salter 2005).

  • a Species name abbreviations: Pam, P. amoena; Pcy, P. cyanea; Pca, P. caerulea; Pro, P. rositae; Ccy, Cyanocompsa cyanoides.

  • b This was also the topology recovered in all the unconstrained searches, which also gave identical ln L scores.

  • c These data sets included all sequence data from all loci.

  • d This data set included only the largest independently segregating block of sequence for those loci showing evidence of recombination.
