The biogeography and age of salticid spider radiations (Araneae: Salticidae)

► Four gene phylogeny confirms strong geographical affiliation of major clades. ► Most African rainforest-dwellers appear to fall into one clade, the thiratoscirtines. ► Bayesian analysis indicates radiation of major clades 47-20 million years ago. ► The new Saltafresia includes plexippoids, aelurilloids, euophryines, and others.
