Literature: (Hendey 1964, p. 281, pl. 39, fig. 6; Witkowski et al. 2000, p. 368, pl. 199, figs. 5, 6).

Description: Length 82–105 µm, width 8–12 µm, fibulae 5–6 in 10 µm.

Remarks: Striae are very fine and difficult to resolve under LM, normally appearing mottled as a result of crossing transverse and oblique lines.

Ecology and distribution: Widely distributed species in temperate and North European waters (Hendey 1964). Also recorded in the sea-ice of the Arctic (Hsiao 1980) and from surface sediment in Antarctica (Prasad and Nienow 1986). Frequent in Potter Cove.
