Valve face weakly convex, mantle rounded, distinctly indented at base where it meets expanded hyaline valve margin with raised border. Valve covered with false pseudoloculi, basal layer with poroid areolae, radially aligned. Poroid areolae occluded by two types of vela, mostly cribra with occasional specialised pore present. Rimoportulae single (rarely two), submarginal or at foot of elevation. Valve interior with uninterrupted radial rows of poroid areolae. Valvocopula distinct, with broad pars interior and inner row of elongate pores.
