Introduction
The family Asterometridae is known from the Indonesian-Japanese region and from northern Australia. Two genera are known and both are recorded in Australian waters, each represented by two species.
Asterometrids are similar to members of the family Ptilometridae but are distinguished from them and other comatulids by the following features: the centrodorsal is small and more or less pentagonal with a conical apex, the relatively few cirri are arranged in 10 definite columns each of 2–3 sockets, and the radial areas of the centrodorsal are separated from each other by distinct ridges.
