Two new freshwater species of the small family Capilloventridae are recorded from rivers in south‐eastern Australia. Capilloventer acheronensis sp. n. has all hair setae anteriorly and dissimilar crotchet setae without hairs posteriorly while Capilloventer longicapitus sp. n. has an elongate prostomium, very long hair setae anteriorly and all bifid setae posteriorly. Immature specimens from south‐west Western Australia appear to represent a further species and are tentatively included within the family. Additional specimens of Capilloventer australis Erséus, 1993 have allowed some features (setae, segmental glands, genitalia and ventral buccal organ) to be described in more detail. The new C. australis specimens are from the upper reaches of Victorian rivers, showing that it is a freshwater species, rather than a marine incursion as the estuarine type locality suggested. There are now more freshwater species than marine species, although the origin and phylogenetic relationships of the family remain unclear.
