General environment
This is a marine species.

Description
Cells with two yellow-brownish chloroplasts, one in each end. Cells rectangular in girdle view. Valves linear to lanceolate with parallel valve margins in middle part. Valves 32-82 µm long, 1.4-2.9 µm wide. External surface of the frustule smooth. Uniseriate striae 4453 in 10 µm. Round-oval areolae, 3.9-7.7 in 1 µm, with hymen close to the external surface. Hymen perforated by circularly arranged pores along the hymen margin, internally more chaotic. Interstriae raised above the internal plane of striae. Mantles structured as the valve face, 1-2 poroids high. Extremely eccentric canal raphe. Wall of canal raphe perforated by areolae. Fibulae irregularly spaced, 7-19 in 10 µm. Two central fibulae with larger interspace than remaining fibulae, corresponding to the central nodule. Raphe slit ends in simple central raphe endings. Internal distal raphe endings end in helictoglossa, forming an excrescence. Outer distal raphe endings extend to cell end and curve towards the side of the valve forming a hook. Epicingulum comprises 2-10 open bands. Each band contains 1-2 longitudinal rows of areolae, 5-12 areolae in 1 µm in the valvocopula. In the most distal band, areolae are more irregularly spaced.
