Benthic species of Dorylaimus Dujardin 1845 (Nematoda: Dorylaimidae) and Arctidorylaimus n.gen. (Arctidorylaimidae n.fam.) from the Mackenzie and Porcupine river systems, Northwest Territories, Canada
Arctidorylaimidae n.fam. and Arctidorylaimus n.gen. are proposed to accommodate A. arcticus n.sp., a dorylaimid with longitudinal body ridges from aquatic habitats. A diagnosis of the family and genus, key to closely related genera, and description and illustrations of the new species are provided....

| Summary: | Arctidorylaimidae n.fam. and Arctidorylaimus n.gen. are proposed to accommodate A. arcticus n.sp., a dorylaimid with longitudinal body ridges from aquatic habitats. A diagnosis of the family and genus, key to closely related genera, and description and illustrations of the new species are provided. The main differential characters of these new taxa are the offset head, short, conoid tails in both sexes, and the spaced, mammillate supplements of the male. Dorylaimus lineatus, a new record for Canada, and Dorylaimus stagnalis are described from Canadian populations and their diagnostic characters compared and illustrated. The genus Dorylaimus is reviewed and a key, supplemented with tabulated characters and references, is provided for all valid species. Dorylaimus amplexor and Dorylaimus sulcatus are placed in species inquirendae. |
