dc.description.abstractSubtribe Withaniinae (Solanaceae) comprises seven genera and c. 40 species, with an almost cosmopolitan distribution. Athenaea and Aureliana are exclusively South American, with diversity centres in the Brazilian Atlantic Rainforest. The generic status of Athenaea and Aureliana was investigated using molecular phylogenetic analysis of five plastid regions (ndhF gene, trnL intron and trnL-trnF, psaI-accD and trnC-ycf6 intergenic spacers), nuclear internal transcribed spacers (ITS) and morphometric analysis of the calyx. Divergence time estimates were also performed. Withaniinae was recovered as monophyletic. The diversification time estimated for Withaniinae was 6.3 Myr, and the estimated diversification time for the Athenaea and Aureliana clades was 2.3 Myr. Athenaea and Aureliana species formed a strongly supported clade. However, the genera were not monophyletic, and support for internal relationships was moderate to weak. The morphometric analysis of the increasing size of the fruit calyx that included all species of the genera showed a cline that did not allow us to conclude that the species could be separated into two genera. Because the accrescent calyx is the only morphological character that distinguishes them, we recognize Athenaea as a synonym of Aureliana and propose five new combinations. The list of accepted species is presented.en
