Table 1.

The eight oldest taxon-poor lineages as identified by the chronogram in figure 1 and the null models in the electronic supplementary material, figure S3 and their contemporary distributions. (These lineages represent relictual taxa and may correspond to taxon cycle stage IV. Also indicated are altitudinal distributions (L =<200 m.a.s.l., M = 200–1000 m.a.s.l., H >1000 m.a.s.l.) and preferred habit requirements (A, all habitats; UF, undisturbed forest; DF, disturbed forest (incl. edge and woodland); CH, coastal habitat; SL, scrubland).)
