Introduction
Only two extant genera are known in the family Echinolampadidae, occurring in circum-tropical waters. One species is recorded in the Australian fauna.
The family is distinguished from other cassiduloid echinoids by the following combination of character states: size medium to large; usually ovoid; petals long, open, usually with unequal poriferous zones, single pores in ambulacral plates beyond petals; periproct inframarginal, bourrelets well developed; phyllodes widened, with few or many pores; narrow, naked, granular zone in interambulacrum 5; buccal pores.
