Introduction
The family Astriclypeidae includes only two extant genera, known from the Indo-West Pacific region. One genus and two species are recorded in Australian waters.
The family is distinguished from other clypeasteroid families by the following combination of character states: medium to large sized, flattened; margin thin; internal skeletal supports well developed, with paired posterior ambulacral lunules or notches; anterior ambulacral lunules present in some forms; petals well defined; posterior interambulacra discontinuous, others variable; interambulacra about as wide as ambulacra at ambitus; periproct on oral side; food grooves bifurcating just outside primordial plates.
