| Summary: | Angusticopula cosmica Goeyers & Van de Vijver sp. nov. http://phycobank.org/ 102315 Figs 28–43 Etymology The specific epithet refers to the general outlook of the valves in scanning electron microscopy giving the impression, due to the many granules, of a cosmos with numerous stars. Material examined Holotype CAMPBELL ISLAND • sub-Antarctic region; sample BAS303; 12 Jan. 1970; D. Vitt leg.; BR-4577. Isotype CAMPBELL ISLAND • same collection data as for holotype; slide at University of Antwerp, Belgium; PLP-368. Description Light microscopy (Figs 28–36) Frustules rectangular with valve diameter much larger than the mantle height. Cells always solitary; chains, even short ones, never observed. Numerous discoid plastids present. Valve diameter (n = 50): 18–45 μm, mantle height (n = 1): ca 8 μm. Valves with a low mantle and flat valve face. Internal valves never observed. Central area large, diameter 10–25 μm (50–60% of the total valve diameter, irregularly bordered by marginal striae. Marginal striae ... : Published as part of Goeyers, Charlotte & Vijver, Bart Van De, 2020, Revision of the non-marine centric diatom flora (Bacillariophyta) of the sub-Antarctic Campbell Island (southern Pacific Ocean) with the descriptions of five new species, pp. 1-30 in European Journal of Taxonomy 694 on pages 6-9, DOI: 10.5852/ejt.2020.694, http://zenodo.org/record/3973347 ... |
