    Lip region one-fourth as wide as neck base, set off by deep constriction.  Amphids practically encompassing lip region.  Lips angular.  Vestibule with typical four plates.  Spear length twice lip region width, generally dorsally arcuate.  Esophagus enlarged by gradual expansion slightly posterior to middle until two-thirds neck width.  Nuclei of esophageal glands arranged much like those of EnchodelusCardia elongate-hemispherical.  Intestine six cells in circumference, granules dark brown or metallic in appearance.  Prerectum length two to three times body width.  Rectum length about one and one-half times anal body diameter.  Ovaries long, reflexed about half way to vulva.  Supplements 11-14, rather uniformly spaced, three within range of spicula.  Spicula dorylaimoid with an abrupt ventral angle.  Accessory pieces short, tapering. Female tailbluntly convex conoid.  Male tail dorsally arcuate. Saccate bodies about fifteen on each side of female tail and eight or ten on male.

    Diagnosis: Pungentus with the above measurements and general description.  Distinctive because of the deeply set off, angular lip region, number and arrangement of the supplements and Enchodelus-like arrangement of the esophageal gland nuclei.  Obviously this species represents a bridging type between Enchodelus and Pungentus.

    Habitat: Soil about native plants, Ogden Canyon and Bells Canyon, Utah, U.S.A.
