Type species: Emslandia emslandensis Gerlach, 1961; emend. Benedeck and Sarjeant, 1981
Translation Gerlach, 1961: LPP
Original diagnosis: Gerlach, 1961, p. 171
Theka round to ovoidal with short apikal protrusions, without inner body and without tabulation. Girdlefurrow strongly spiral and indented. Longitudinal furrow more or less clear, relatively narrow.
Emended description: Benedek an Sarjeant, 1981, p. 315-316
Cyst proximate, subglobular to ovoidal or rounded-pentagonal, with or without an apical mamelon or horn. Phragma thick, two-layered, with endophragm relatively thin, periphragm much thickened and sometimes containing cavities which may, or may not, be open. Paracingulum clearly or faintly indicated parasulcus clearly or faintly indicated or indicated only by offset of the two ends of the paracingulum.
