A new species of hairworm, Parachordodes tegonotus n. sp. (Gordioidea: Nematomorpha) is described from three species of ground beetles (Carabidae: Coleoptera) from the state of Oregon. This is the first record of Parachordodes Camerano parasitising carabid beetles in North America. Diagnostic characters for the new species include size, colour, the nature and arrangement of the areoles, and the character, shape and extant of ornamentation on the ventral surface of the male tail. Encysted hairworm larvae found in the internal tissues of mayfly and caddisfly larvae at the type-locality were presumed to be those of P. tegonotus, indicating an indirect life-cycle involving paratenic hosts. A worldwide host list shows that some 70 species of ground beetles have been documented as developmental hosts to hairworms belonging to at least five genera, namely Gordius, Parachordodes, Dacochordodes, Gordionus and Paragordionus.
