Heibergella kendelbachia.(Morbey, 1975) Lentin and Williams, 1981. In part from Morbey (1975). Cyst proximate, rhomboidal, occasionally spheroidal, ovoidal in shape. Wall thin, reticulate and punctate. Vaguely to distinctly ornamented with random, sparse or densely distributed processes up to ca. 2 µm in length, sometimes distinctly denser at apices and laterally at equator. Processes with conical, tapered cylindrical, and slender-like stems, and simple or bifurcate terminations. Cingulum defined by one or two transverse folds, occasionally by discernible sutural ridges (septa). Sulcus seldom distinguishable. Tabulation indeterminate if present. Archeopyle intercalary, type I, 2I or 3I, operculum free or displaced. Size: length 48-69 µm, cingulum diameter 37-50 µm, cingulum 8-15 µm wide.
--------------------------------------------------
Original diagnosis: Morbey, 1975, p.38: Rhombodella kendelbachia
Cyst proximate, rhomboidal, occasionally spheroidal, ovoidal, in shape. Wall thin, reticulate and punctate. Vaguely to distinctly ornamented with random, sparse or densely distributed processes, upto ca. 2 µm in length, sometimes distinctly denser at apices and laterally at equator. Processes with conical, tapered, cylindrical, and slender hair-like stems, and simple or bifurcate terminations. Cingulum defined by one or two transverse folds, occasionally by discernible sutural ridges (septa). Sulcus seldom distinguishable. Tabulation indeterminate if present. Archeopyle, when evident, apical. Apical orientation of specimens difficult unless excystment has taken place.
Dimensions: Apical length 48(57)69 µm 12 specimens measured). Cingulum diameter 37(45)50 µm. Apical length: Cingulum diameter 3:2-6:5 µm. Cingulum ca. 8-15 µm in width.
