Vadet (1991) distinguished this taxon from Rhabdocidaris primarily because of its relatively coarse scrobicular tubercles and because its ambulacral tubercles are "not incised". These features seem very minor, and the partially dolomitised type specimens provide very poor preservation of tuberculation. However, the spine morphology is distinctly different, spines of Rhabdocidaris being often rather flattened and with spinose ornamentation, whereas those of Laurenticidaris, if correctly attributed, are irregularly pustular. The other species associated here, however, has more typical thorned spines.
Cotteau originally asigned this to the Upper Toarcian but according to Vadet (1991) this is now considered Lower Aalenian.
