Original description Diagnosis. A primitive Plectofusulina with a poorly differentiated diaphanotheca, small chomata and weak septal folding.
Original description Diagnosis. A primitive Plectofusulina with a poorly differentiated diaphanotheca, small chomata and weak septal folding. Description. Test small, ellipsoidal with pointed poles and strongly convex lateral slopes. Diameter (D) = 0.565–0.800 mm (rarely1.200 mm) (Holotype = 0.565 mm); width (w) = 0.850–1.000 mm (rarely 1.880 mm) (Holotype = 0.850 mm); w/D = 1.17–1.57 (Holotype = 1.50); proloculus diameter = 0.050–0.100 mm (Holotype = 0.050 mm); number of whorls: 3.5–4 (Holotype: 4); number of chambers: 13–17; height of last whorl = 0.100–0.300 mm (Holotype = 0.100 mm); wall thickness = 0.010–0.025 mm (Holotype = 0.010 mm). Proloculus spherical, moderately broad for the genus. Septal loops are very discrete. Deviations of axis of coiling are moderate. The height of the chambers increases slowly. Wall microgranular with a very faint diaphanotheca. Chomata moderately developed, extend third to half the chamber height, relatively symmetrical and tuberiform. Tunnel irregular to straight. Type level. Early Desmoinesian. Type locality. Cedro Peak (Manzanita Mountains, New Mexico). (Vachard et al. (2013)). [details]
