Central fultoportulae formed by a tube surrounded by two to three satellite pores. Marginal area about one third of valve surface circumferentially undulated with coarse to very coarse striae. Striae of unequal length and density: along major axis 8–12 st/10μm, along minor axis 6–9 st/10μm longer, more outspread and sometimes dichotomous.
