Original Description
Sagittal ring subpolygonal, 58 to 68 microns high, 51 to 63 microns thick, joined directly to front and back of lattice shell. Complete specimens have a slender. apical connector bar and no apical or axial spines. A short vertical spine projects near the base of the sagittal ring. Short broad frontal spine. Single sculptured tubercle arising from base of sagittal ring at intersect with primary lateral processes. On some specimens, the only basal connector bars are primary lateral bars ; other specimens have primary lateral spines and no basal connector bars. A pair of short sagittal-ring spines projects from the front-base of the sagittal ring.
Basal ring oval, indented sagittally, 81 to 109 microns wide, 47 to 61 microns thick, enclosing two or four basal pores. Basal ring joined to front-middle and back-base of sagittal ring ; lattice bars joined to basal ring irregular in number and position. Lattice shell 102 to 132 microns wide, 84 to 150 microns high, surrounding apex and base of sagittal ring; slight horizontal constriction at basal ring. Broad lattice bars separate small, subrounded, lattice pores on the lateral portions of the lattice shell. Three pairs of very large, sagittal lattice pores are covered by thin, perforate, lattice plates. Portions of lattice shell surrounding apex and base of sagittal ring composed of delicate, smooth, lattice bars separating many small, subcircular lattice pores. Three tribladed lattice bars joined to middle and apex of sagittal ring. Some or all of these tribladed lattice bars and the front and back of the basal ring bear symmetrical pairs of short lattice spines. No frontal, vertical or sternal pores or lattice-shell tubercles.
