Abstract

The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow&hyphen;water tropical carbonate, coral reef&hyphen;related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y&hyphen;shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil ( B. pygmaea , B. inflata , B. philippinensis , B. melo , B. curdica ), and from fossil and modern ( B. pulchra , B. schlumbergeri ) specimens. For the first time, fossil and Recent Borelis specimens are illustrated via micro&hyphen;computed tomography scanning images. Depending on the occurrence of Y&hyphen;shaped septula, two lineages are distinguished. Deriving from the middle–upper Eocene Borelis vonderschmitti , the first lineage includes B. inflata , B. pulchra and B. pygmaea , lacking Y&hyphen;shaped septula. The first species bearing Y&hyphen;shaped septula is the Rupelian B. philippinensis of the western Indo&hyphen;Pacific. The westward migrants of B. philippinensis into the Mediterranean gave rise to B. melo (Aquitanian–Messinian) and B. curdica (Burdigalian–Tortonian). These two species became isolated from the Indo&hyphen;Pacific by the Langhian eastern closure of the Mediterranean basin and disappeared during the Messinian Salinity Crisis. Since the Tortonian, B. schlumbergeri , which descended from B. philippinensis , has inhabited the Indo&hyphen;Pacific along with B. pulchra . From the central Pacific Ocean, B. pulchra reached the Caribbean area before the early Piacenzian closure of the Central America seaway.
