The polychaete worm family Pectinariidae is represented in Australian waters by five species (
Amphictene favona n.sp.,
A. uniloba n.sp.,
Pectinaria antipoda Schmarda, 1861,
P. dodeka n.sp. and
P. kanabinos n.sp.).
Pectinaria antipoda is redescribed and a neotype designated. Generic diagnoses are given for all genera including three not known from Australian waters. Additional characters are described for each genus that may facilitate the separation of species. A key to all genera and to species present in Australia is given, as are tables summarising the characters of all described species.
