Lepidechinus is close to Pholidechinus in structure, but differs from that taxon in having strictly uniserial pore-pairs, pore-pairs being biserially offset in Pholidechinus. Interambulacral plates are more regularly organised and a little thicker than in Palaeodiscus, and much fewer than in Myriastiches.
