Dimensions. d=18 x 22 mm; s=96.

Description. Solitary, bowl-shaped; septa crowded, arranged in 5 complete cycles in 6 systems; fossa deep.

Remarks. Umbgrove (1925) based his new genus Porosmilia on the same specimen that Dietrich (1917) used for his genus Areopsammia . Because Umbgrove's taxon is a junior synonym, Dietrich's Areopsammia has priority. Moreover, the generic name Porosmilia was previously used by de Fromentel (1860). Therefore, Umbgrove's taxon is a junior homonym.

Type locality of species. Maastrichtian of The Netherlands (St. Pietersberg) .

Distribution. Maastrichtian of The Netherlands.
