Description: Length of valve side 118–127 µm, areole 2.5– 3 in 10 µm. Figures 27 – 38: Marine benthic diatoms in Potter Cove, King George Island, Antarctica, summer 2015. (27) Corethron pennatum . (28) Fragilaria striatula . (29) Synedropsis sp. (30) Licmophora Remarks: Specimens observed had slightly convex valve margins and coarser areole. Valve outline appears similar to Triceratium broeckii but in this species areole clearly decrease in size at the center. antarctica . (31–32) Licmophora belgicae . (33) Licmophora gracilis .
