03B6B918FFFFFFC7B1B763AD16D9F353.taxon	description	SEM: Sternum valve: Striae regularly spaced, slightly radiate (Figs 14 – 16). SV areolae small, slightly elongate and decussate (no axial rows of SV areolae). Hexagonal areola pattern (i. e., honeycomb-like) with a decussate regular arrangement, as observed in a corroded SV (Fig. 15). One marginal row of elongate areolae present (Fig. 15); hyaline marginal area absent (Fig. 15). SV sternum narrow (Figs 14, 16), very slightly enlarged on central area before last quarter of valve (Fig. 15 arrows). SV corroded areola hymenes (Fig. 20 arrowhead) with probable slits perpendicular to the areola walls. SV marginal supplementary short striae present (Fig. 16 arrowheads); often one stria slightly shorter in center, on one side of valve (not shown). Internal side: presence of a round to oblong foramina (Figs 25 – 26). Marginal SV areolae covered (funnel-like, Fig. 25 arrow) with lateral foramina (Fig. 25 arrowhead). Sternum valve valvocopula (SVVC, Figs 23, 27 arrowheads) as an open and imperforated large band, without fimbriae (Figs 22, 24 arrow). SV sternum thickened (Fig. 24). Cingulum composed of 4 narrow open copulae (Figs 18, 34), up to 6 (not shown). Raphe valve: Valve weakly silicified, flat to slightly concave (Figs 29, 34). Striae regularly spaced, parallel to radiate close to apices, composed of small round areolae. One row of marginal slightly elongate areolae (Fig. 32 arrowheads). Raphe sigmoid, proximal raphe endings straight, simple and close together, terminal raphe endings close to margin (Figs 33 – 34). Short hemi-fascia (Fig. 30 arrow), sometimes almost lacking (Fig. 32). Axial area narrow. RV areolae externally closed by hymenes with radiate slits (Fig. 35). Internally, raphe located in an elevated axial area (Figs 36 – 39). Raphe valve valvocopula (RVVC) open (Fig. 34), without fimbriae (Fig. 38 arrowhead). Terminal raphe endings bent in opposite directions (Fig. 36). No areolae on apices (Fig. 39). Diagnostic features of Cocconeis kurakakea sp. nov.: The new species is characterized by its small size, linear-elliptic shape, and RV and SV striae that are almost undetectable with the LM. Using the LM we can only distinguish the asymmetrical small RV fascia (hemi-fascia), the decussate pattern on the SVs and the sigmoid structure of the SV sternum and raphe. With the SEM, the SV areola structure and pattern, the RV hemi-fascia and high cingulum make the species easily distinguishable.

03B6B918FFFFFFC7B1B763AD16D9F353.taxon	etymology	Etymology: The epithet kurakakea refers to the marae Kurakakea, located in the village of Tavananui (Nukutavake, Tuamotu Archipelago). This marae (ancient sacred site where religious and tribal ceremonies were celebrated), the most important marae of the atoll, was destroyed by a cyclone in 1983. Habitat: Undetermined filamentous green macroalgae on the coral reef slope.	en	Riaux-Gobin, Catherine, Witkowski, Andrzej, Jordan, Richard W., Parravicini, Valeriano, Planes, Serge (2018): Cocconeis kurakakea, a new diatom species from Nukutavake (Tuamotu Archipelago, South Pacific): description and comparison with C. diruptoides and C. pseudodiruptoides.

03B6B918FFFFFFC7B1B763AD16D9F353.taxon	distribution	Distribution: Presently, the new taxon is only recorded from Nukutavake, and hence may be narrowly endemic.	en	Riaux-Gobin, Catherine, Witkowski, Andrzej, Jordan, Richard W., Parravicini, Valeriano, Planes, Serge (2018): Cocconeis kurakakea, a new diatom species from Nukutavake (Tuamotu Archipelago, South Pacific): description and comparison with C. diruptoides and C. pseudodiruptoides.
