Heterohelicodea is a superfamily of globigerid forams with planispiral or enrolled biserial tests, found in marine sediments of Early Cretaceous to the present, in which chambers vary from globular to elongate and the primary aperture is equatorial in position. It is in the suborder Rotaliina and the order Rotaliida.. Heterohelicoidea includes three families, the Chiloguembelinidae, Guembelitriidae and the Heterohelicidae, the latter are divided into three subfamilies
