Similar to interambulacral plate fragments referred to as Mesodiadema by Kier (1968) and others in having wide adradial and interradial zones of secondary tuberculation, but differs from that taxon in having strongly crenulate tubercles. The type species of Mesodiadema is a primitive Irregularia from the Lower Jurassic and its relationship to the Triassic material unknown. Lenticidaris differs from Miocidaris in having wider interambulacral plates which are much more imbricate and spines that are smooth.
Isolated interambulacral plates from the Carnian of Italy have been attributed to this genus by Vadet (2000). However, such plates are strictly indeterminate and could belong to one of a number of different genera.
