Tubificoides kozloffi sp.nov., and Tubificoides brevicoleus sp.nov. are described from intertidal habitats of Washington and British Columbia. Tubificoides foliatus sp.nov., a species previously identified as belonging to the Tubificoides gabriellae complex, is described from California and British Columbia. Tubificoides cuspisetosus sp.nov., Tubificoides palacoleus sp.nov., and Tubificoides crenacoleus sp.nov. are described from the Arctic. A key to the species-groups of Tubificoides is given.
