ISOTYPE: An isotype from North Arm was deposited in the Muséum National d’ Histoire Naturelle – Paris, as no. PC 0776066. Material from the 3 live cultures fixed in CTAB buffer was deposited in the Muséum National d’ Histoire Naturelle – Paris, accompanying the isotype specimen, as no. PC 0776066. TYPE LOCALITY: Blue Beach, San Carlos, East Falkland, Falkland Islands, 51 º 34.2676 ʹ S, 59 º 2.1236 ʹ W. The type locality of this species at San Carlos is historically significant as the landing site of the forces who liberated the Falkland Islands in 1982.	en	Küpper, Frithjof C., Peters, Akira F., Kytinou, Eleni, Asensi, Aldo O., Vieira, Christophe, Macaya, Erasmo C., De Clerck, Olivier (2019): Dictyota falklandica sp. nov.

C7329803FFCF431D502E67F2FA0ABC5F.taxon	description	Vegetative and reproductive morphology Dictyota falklandica grew upright, but lacked a conspicuous base. The species was attached by patches of rhizoids, present near basal parts of thalli (Fig. 8). Apices were obtuse, with protruding lens-shaped apical cells. Irregular branching in the apical parts of thalli might be related to regained meristematic activity of additional apical cells which dot the margins of the apical parts of the thallus (Figs. 7, 9). Dichotomies were evenly spaced every 13 – 15 mm. The branching angle was approximately 45 – 50 °. Surface and margins were smooth, and lacked teeth or proliferations (Fig. 11). The thallus was composed of a single-layered cortex and medulla (Figs. 13 – 15). Tangential divisions of cortical and medulla cells, resulting in a multi-layered cortex or medulla, were not observed, not even in the most basal regions. Cells contained multiple discoid plastids devoid of pyrenoids. Cortical cells were rectangular to nearly isodiametric in surface view (Fig. 9), (22 –) 30 (– 38) μm long, (12 –) 17 (– 22) μm wide and 10 – 12 μm high (Figs. 12, 14). Medullary cells were (77 –) 101 (– 129) μm long, (46 –) 57 (– 77) μm wide (Fig. 9) and 95 – 120 μm high (Fig. 14). Male and female gametophytes were not observed. Immature sporangia occurred in irregular groups or longitudinal lines on the thallus surface (Fig. 12). Sporangia were not surrounded by an involucrum and were borne on a single stalk cell. Thalli had tufts of hairs randomly scattered on both surfaces (Fig. 13).	en	Küpper, Frithjof C., Peters, Akira F., Kytinou, Eleni, Asensi, Aldo O., Vieira, Christophe, Macaya, Erasmo C., De Clerck, Olivier (2019): Dictyota falklandica sp. nov.

C7329803FFCF431D502E67F2FA0ABC5F.taxon	biology_ecology	Temperature tolerance Two months after the start of the experiment, cultures of the three isolates exposed to 25 ° C for 11 days showed clear signs of stress – two were dead, and one culture was mostly bleached with only small tissue parts remaining pigmented. In contrast, the cultures at 20 or 15 ° C for the same duration had healthy (brown – dark brown) pigmentation and growth.	en	Küpper, Frithjof C., Peters, Akira F., Kytinou, Eleni, Asensi, Aldo O., Vieira, Christophe, Macaya, Erasmo C., De Clerck, Olivier (2019): Dictyota falklandica sp. nov.
