Guatteria (Annonaceae) is, with 265 species, the third largest genus of Neotropical trees after Inga (Fabaceae) and Ocotea (Lauraceae), and its widespread distribution and frequent occurrence makes the genus an excellent model taxon to study diversification patterns. This study reconstructed the phylogeny of Guatteria and inferred three major biogeographical events in the history of the genus: (1) a trans-oceanic Miocene migration from Central into South America before the closing of the Isthmus of Panama; (2) a major diversification of the lineage within South America; and (3) several migrations of South American lineages back into Central America via the closed Panamanian land bridge. Therefore, Guatteria is not an Amazonian centred-genus sensu Gentry but a major Miocene diversification that followed its dispersal into South America. This study provides further evidence that migration into the Neotropics was an important factor in the historical assembly of its biodiversity. Furthermore, it is shown that phylogenetic patterns are comparable to those found in Ocotea and Inga and that a closer comparison of these genera is desirable.10aAnnonaceae10aDispersal10aGuatteria10aNeotropics10aRainforest trees10aRapid diversification1 aErkens, Roy, H J1 aChatrou, Lars, W1 aMaas, Jan, W1 aNiet, Timotheus1 aSavolainen, Vincent uhttps://annonaceae.myspecies.info/node/506002224nas a2200241 4500008004100000245013100041210006900172300001200241490000700253520141300260653001501673653001401688653001401702653001501716653002101731653002601752100002101778700002101799700001701820700002001837700002401857856010101881 2007 eng d00aA rapid diversification of rainforest trees (Guatteria; Annonaceae) following dispersal from Central into South America0 arapid diversification of rainforest trees iGuatteriai Annonaceae a399-4110 v443 a
