038DF813516962391BDBFEE9E096FC2E.taxon	discussion	Notes: Regarding the differences between C. undatus and C. tonlesapensis, Tudesque & al. (2021) indicated, apart from the different interpretation of the cuculli, differences in the eccentricity of the central area as well as differences in areola and stria density. Following a comparison with the original description, some issues with the scale bars given by Stoermer & al. (1990) were noted, resulting in different values with, for example, areolar density of ca. 30 – 120. What appears to be a larger valve in Fig. 5 would be less than 3 µm in diameter (Stoermer & al. 1990), which is well below the given minimum of 10.5 µm. There may be the need for a more detailed comparison of both taxa to determine and document the relevant differences.	en	Schultz, Konrad, Tudesque, Loïc, Vijver, Bart Van de (2024): Transfer of Stephanodiscus tonlesapensis Tudesque, Le Cohu & Van de Vijver to the genus Cyclotubicoalitus (Stephanodiscaceae, Mediophyceae).
