Abstract
A new Nearctic lumbriculid genus, Eremidrilus, includes four new California species (E. elegans, E. coyote, E. ritocsi, and E. felini) plus the new combination of Trichodrilus allegheniensis Cook, 1971 from the eastern U.S.A. Eremidrilus has the Trichodrilus arrangement of reproductive organs, but is distinguished by a filiform proboscis and male pores on folded porophores. A combination of other characters distinguishes most Eremidrilus species from most Trichodrilus species: (i) elongate-tubular thin-walled atria, (ii) posterior vasa deferentia forming a loop in XI, (iii) no posterior blood vessels, (iv) nephridia not present in VII. Spermathecae restricted to the first postatrial segment and laterally displaced spermathecal pores differentiate the western Eremidrilus species from the single eastern species. ?? 2003 NRC.
