Exosphaeroides fluvialis gen. et sp.n. is recorded from a number of estuaries along the mainland coast of Queensland and Cymodetta gracilipes sp.n. is recorded from sediment amongst mangroves and in a ‘dry’ location on Lizard Island, in the Great Barrier Reef. The brackish water species Cymodetta gambosa Bowman & Kühne is redescribed and the genus is transferred from the hemibranchiate to the platybranchiate group of Sphaeromatidae. Another brackish water sphaeromatid, Exosphaeroma alatum Baker, is also redescribed and is removed from the hemibranchiate Sphaeromatidae to form the type‐species of a eubranchiate genus, Ptyosphaera gen.n. Details are given of the occurrence of sphaeromatid isopods in brackish water in Australia. Sphaeroma triste Heller, a wood‐boring sphaeromatid, is reported from Australia for the first time. A discussion is given concerning the colonization of brackish water and freshwater by sphaeromatids throughout the world.
