Buccella is a genus of late Cenozoic benthic foraminifera that made its first appearance during the Oligocene and is found living in recent oceans.
Buccella, named by Andersen, 1952, is assigned to the Trichohyalidae, a family making up part of the rotaliid superfamily Chilostomellacea.
The aperture is interiomarginal, midway between umbilicus and periphery, and may be partially covered by the umbilical granules.
Mesorotalia McCulloch, 1977, appears to be a junior synonym.
Aubignyna, Neobuccella, and Trichohyalus are related genera.
