Test attached, early stage probably free, ovate in outline, chambers in polymorphine or pyruline arrangement, low, strongly over-lapping the earlier chambers and separated by oblique sutures, later with a narrow to broad keel-like to flangelike chamber attached to the substrate and surrounding the earlier part of the test; wall calcareous, hyaline, perforate radial, surface smooth; aperture terminal, slit-like. L. Cretaceous (Albian) to Holocene; cosmopolitan.
 
Remarks: Lingulopyrulinoides was described as a polymorphinid with biserially arranged chambers and a marginal keel completely surrounding the test but appears to be a Webbinella that has been detached from the substratey
