). Ocellulimbi were deeply sunken, 3–4 pores tall and 6–12 pores wide, and were overhung by 5–6 spines. There was a rimoportula at each pole, with symmetrical coverings that were slightly oblique to the transapical axis, and being about 2.0–2.2 μm from the end of the valve. The external opening of the rimoportula was a slit-like pore. The striae were biseriate. The walls were bilayered with a single pore internally per chamber. The girdle bands were smooth and open.
, which was similar in morphology, but whose sternum was generally prominently lanceolate and whose pore field was about twice as wide as measured by the number of pores.
