|H. Kozur and W. Sadeddin 1990||Sieve-plates with long, perforated arms and broad, thickened margin. Central pore very large, surrounded by a ring-like wall. Other pores small, in the arms often biserially arranged. A large stirrup with a robust, but short 4-edged spine is elevated above the central pore. The 4 feet of this stirrup are basally bifurcated, and reach far beyond the margin of the central pore. The lower side of the central pore is partly closed by a finely perforated lattice|
