  abstract = {{A}frican rainforests ({ARF}s) are species rich and occur in two main rainforest blocks: {W}est/{C}entral and {E}ast {A}frica. {T}his diversity is suggested to be the result of recent diversification, high extinction rates and multiple vicariance events between west/central and {E}ast {A}frican forests. {W}e reconstructed the diversification history of two subtribes ({A}nnickieae and {P}iptostigmateae) from the ecologically dominant and diverse tropical rainforest plant family {A}nnonaceae. {B}oth tribes contain endemic taxa in the rainforests of {W}est/{C}entral and {E}ast {A}frica. {U}sing a dated molecular phylogeny based on 32 nuclear markers, we estimated the timing of the origin of {E}ast {A}frican species. {W}e then undertook several diversification analyses focusing on {P}iptostigmateae to infer variation in speciation and extinction rates, and test the impact of extinction events. {S}peciation in both tribes dated to the {P}liocene and {P}leistocene. {I}n particular,{P}iptostigma(13 species) diversified mainly during the {P}leistocene, representing one of the few examples of {P}leistocene speciation in an {A}frican tree genus. {O}ur results also provide evidence of an {ARF} fragmentation at the mid-{M}iocene linked to climatic changes across the region. {O}verall, our results suggest that continental-wide forest fragmentation during the {N}eogene (23.03-2.58 {M}yr), and potentially during the {P}liocene, led to one or possibly two vicariance events within the {ARF} clade {P}iptostigmateae, in line with other studies. {A}mong those tested, the best fitting diversification model was the one with an exponential speciation rate and no extinction. {W}e did not detect any evidence of mass extinction events. {T}his study gives weight to the idea that the {ARF} might not have been so negatively impacted by extinction during the {N}eogene, and that speciation mainly took place during the {P}liocene and {P}leistocene.},
