Hydrothecal rim uneven, with two large cusps, separated by two large embayments (Fig. 4A). Operculum composed of two semi-circular, pleated valves, attached to rim embayments and closing as a roof.
Measurements (in µm). Hydrotheca: diameter at aperture 220–230; height, up to diaphragm 730–800, diameter at diaphragm 80–100, length of pedicel 100.
Ecology and distribution. Eurybathic species, found at depths from 0.5 (García Carrascosa 1981) to 1214 m (Schuchert 2001); the present material was collected from the Porcupine Seabight at 150 m, on Sertularella gayi.
