The role of the Panamanian Seaway and its closure for the exchange of goby lineages. During Tortonian and Messinian between 63 and 75% of species were shared between the East Pacific and the West Atlantic. Clades of putative East Pacific origin (blue) persisted in the West Atlantic well up until the Zanclean–Piacenzian interface and in the case of Aruma into the Calabrian. Palatogobius of supposed West Atlantic origin (orange) occurred also in the Calabrian of the East Pacific
