The taxon was erected by Vadet (1991) but without clear differential diagnosis. In Vadet et al. (1996) it is distinguished from Rhabdocidaris in having only the adapical two primary tubercles crenulate, ambital and adoral tubercles being apparently non-crenulate. It is very close in appearance to Nudicidaris, differing only in having subconjugate pore-pairs. Vadet (2004) erected another genus Remycidaris which he separated from Nudicidaris on the basis of its slightly wider pore-pairs. It is likely that both Remycidaris and Guittonicidaris are based on the same type species. All three genera are treated here as synonyms.
