Eighteen species of Tubificidae are reported from intertidal and shallow-water subtidal habitats in the area near Esperance, on the southern coast of Western Australia. Five species are new to science, while all others were previously known from other parts of Western Australia. Pirodriloides breviclitellatus sp. n. differs from P. albanensis (Erséus, 1990), the only other member of Pirodriloides, by lacking penial papillae and numerous coelomocytes. Bathydrilus difficilis sp. n. is partly sympatric with the closely related B. edwardsi Erséus, 1984, but has larger spermathecae (and receives a higher number of spermatozeugmata at copulation) than the latter. Duridrilus globosus sp. n. has spermathecal pores that are ventral instead of lateral, and the openings of its male ducts are less complex than those of the otherwise similar, Saudi Arabian, D. tectus Erséus, 1985. Limnodriloides solitarius sp. n. is closely related to the North Pacific L. macinnesi Erséus, 1990, discriminated only by details in the male ducts; it has larger atrial ampullae and distinct penial papillae inside their copulatory sacs. Finally, Smithsonidrilus fecundus sp. n., known also from Rottnest Island, was previously interpreted as an apomorphic lineage within S. minusculus (Erséus, 1983), characterized by the lack of spermathecae; it is now regarded as a separate taxon. Taxonomic notes are given also for most of the other species reported. A total of 95 species of marine Tubificidae have now been recorded from Western Australia.
