Diagnosis Test small to moderate in size, up to 5.6 mm in length, fusiform to elongate cylindrical, axis of coiling straight to slightly curved, large proloculus followed by about five to eight rapidly enlarging whorls, or may have a much reduced chamber cavity in the last one or two whorls so that successive outer walls are in contact for some distance, the septa of the outer whorl may even penetrate the tectum into the keriotheca of the preceding whorl, septa thick, strongly and irregularly fluted; wall of thin dense tectum and very thick alveolar keriotheca that apparently twists somewhat in the outer volutions so that the alveoli locally appear perpendicular to the surface when viewed in axial section, but nearby in the same thin section the alveoli are seen in cross-section and give the wall a honeycomblike appearance. L. Permian (Artinskian); Thailand. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
