'Stereocidaris' keertii Smith, 2010 is the second cidaroid echinoid being reported 123 years after the first one, i.e. '5.' namadica (Duncan, 1887), on the strength of a single specimen, picked loose, from an abandoned quarry at Karondia, assigning both of them a Turanian age. While keertii, at the first glance, looks very similar to '5. ' namadica, the former has been deemed differentiable from the latter for its wider perradial ambulacral zone filled with smaller, somewhat elongate granules, and the degree of coarseness of the extrascrobicular granulation of their interambulacral plates. In this note it has been argued (with an explanation on the likely reasons for the observed differences between namadica and keertii) that Smith's new taxon (the latter obne) is merely an ecophynotypic variant of namadica !
