Licmophora antarctica Carlson ( Figure 30 )

Literature: (Al-Handal and Wulff 2008b, p. 428, figs. 2–5; Carlson 1913, p. 30, pl. 3, figs. 23, 24).

Description: Length 63–108 µm, width 6–10 µm, striae 10– 12 in 10 µm.

Ecology and distribution: A marine epipelic and epiphytic species. Although L. antarctica is widely distributed in Potter Cove and has been found to be common as epiphytes on most macrophytes (Al-Handal and Wulff 2008b), it does not seem to be widely distributed in other localities in Antarctica. It has been reported by Frenguelli and Orlando (1958) from North Antarctica and from Admiralty Bay ( Fernandez et al. 2014).
