  abstract = {{P}hylogenetic patterns and the underlying speciation processes can be deduced from morphological, functional, and ecological patterns of species similarity and divergence. {I}n some cases, though, species retain multiple similarities and remain almost indistinguishable; in other cases, evolutionary convergence can make such patterns misleading; very often in such cases, the "true" picture only emerges from carefully built molecular phylogenies, which may come with major surprises. {I}n addition, closely related species may experience gene flow after divergence, thus potentially blurring species delimitation. {B}y means of advanced inferential methods, we studied molecular divergence between species of the {V}irola genus ({M}yristicaceae): widespread {V}irola michelii and recently described, endemic {V}. kwatae, using widespread {V}. surinamensis as a more distantly related outgroup with different ecology and morphology-although with overlapping range. {C}ontrary to expectations, we found that the latter, and not {V}. michelii, was sister to {V}. kwatae. {T}herefore, {V}. kwatae probably diverged from {V}. surinamensis through a recent morphological and ecological shift, which brought it close to distantly related {V}. michelii. {T}hrough the modeling of the divergence process, we inferred that gene flow between {V}. surinamensis and {V}. kwatae stopped soon after their divergence and resumed later, in a classical secondary contact event which did not erase their ecological and morphological differences. {W}hile we cannot exclude that initial divergence occurred in allopatry, current species distribution and the absence of geographical barriers make complete isolation during speciation unlikely. {W}e tentatively conclude that (a) it is possible that divergence occurred in allopatry/parapatry and (b) secondary contact did not suppress divergence.},
