Nomenclatural note
Type not designated if a new name was intended. It is possible that this was a new name for Navicula clementis var. rhombica Brockmann, 1950; however, Williams (2024: 35) notes: "Hendey proposed Navicula clementis var. rhombica Brockmann (1950, p. 18, pl. 2, figs 43, 45) as a synonym and, if so, Hendey's name Navicula inclem­entis was probably intended as a replacement name rather than a new species. Navicula clementis var. rhombica was described from the west coast of Schleswig-Holstein and was later transferred to Placoneis rhombica (Brock­mann) Lange-Bertalot (in Metzeltin, Lange-Bertalot & F. Garcia-Rodriguez 2005, p. 195) who noted that Navicula inclementis could not be a synonym as 'size dimensions and striae differ considerably'; they refer to 'Navicula (Placo­neis?) inclementis' (Metzeltin, Lange-Bertalot & F. Garcia-Rodriguez 2005, p. 195). Elsewhere, Placoneis rhombica is considered a synonym of Placoneis cle­mentis (Grunow) E.J.Cox (1987, p. 155, figs 28-33). In short, specimens of Navicula inclementis require further study and if they do indeed belong to Pla­coneis, a new name will be required. To that end, only two slides in Hendey's collection have potential as examples: BM I02546 (Hendey 3357, 'Wales, Anglesey') and BM 12743 (Hendey 3539, 'Wales, Anglesey')." - (22 January 2018) - M.D. Guiry
