There has been no taxonomic study of southern Australian Flabelligeridae since Haswell described several species in 1892, and although at least 3 genera occur in our region, the identity of .local species remains uncertain. Pherusa is the most common flabelligerid in Port Phillip Bay. There appear to be at least 3 species in our region, distinguishable by the number of pairs of branchiae (6 pairs, 10 pairs, or 15 pairs).
Inshore including bays and estuaries, on muddy bottoms, sometimes among seagrass.
