Introduction

The family Pedinidae is circum-tropical in distribution. The single extant genus contains nine species, three of which are recorded in Australian waters.

Pedinidae are the sole family in the order Pedinoida and are distinguished by the following combination of character states: test subspherical, high subconical to depressed hemispherical; plates rigid though fragile, not imbricating; ambulacral plates simple or trigeminate, compound; tubercles perforate, non crenulate; primary spines with solid axis, secondaries hollow; globiferous pedicellariae terminate in two–three teeth, two types of ophicephalous pedicellariae; lantern diadematoid-type.
