ARENAGULA Bourdon and Lys, 1955

 

 

Type species: Arenagula globula Bourdon and Lys, 1955; OD.

Arenagula Bourdon and Lys, 1955 (*318), p. 336.

Test large, about 1.25 mm in greatest breadth, chambers forming a low trochospiral coil, five chambers in the first whorl, later increasing in breadth and number as the whorl expands rapidly, spiral side convex, umbilical side flattened; wall agglutinated, canaliculate, may have incipient pillars projecting slightly from the septa; aperture valvuline in the early stage, later cribrate, consisting of large irregular openings scattered over a con-vex plate covering the umbilicus and final chamber face. M. Eocene (Lutetian) to Oligocene, ?Miocene; France; Greece; USA: Florida; Pacific: Marshall Islands.

 

Remarks: Poignant (1964, *2438, p. 215) regarded Cribrobulimina floridana Cole, 1942, from the Eocene of Florida, and Arenagula globula as conspecific with Lituonella kerfornei Allix, 1922 from the M. Eocene. We regard these as three distinct species of Arenagula.
