Description.
Valves elongate, linear or tapered from a broader apical pole. Wall a single layer usually with internal costae on the virgae, and a pseudoseptum on the rim of the valve at each pole, forming a complex structure with the valvocopula. Midline absent or indistinct (not subtended by a longitudinal costa), annulus usually evident, though sometimes coinciding with the valve-mantle junction.
