L = 2.2 mm; a = 50; b = 5.9; c = 63; V = 57

    Cuticle marked by conspicuous transverse striae.  Lip region about one-third width of neck base, set off by distinct constriction.  Lips well separated and distinct.  Amphids about three-fifths head width.  Cuticular pieces about vestibule easily visible.  Guiding ring double.  Spear slightly longer than lip region width, aperture occupying about one-fourth its length.  Anterior end of esophagus set off from spear extension by expansion, about one-third neck width, continuing about this width until it narrows to pass through nerve ring.  Esophagus enlarged near middle by gradual expansion. Cardia hemispherical.  Prerectum length four times body width.  Rectum length about equal to anal body diameter.  Ovaries reflexed half way to vulva.  Eggs two and one-half times as long as body width.  Lateral cords one-third to one-half as wide as body.  Saccate caudal bodies not observed.

    Diagnosis: Pungentus with the above measurements and general description.  Easily distinguished from other species with double ovaries by its short spear.

    Habitat: Soil about roots of sage, Artemesia tridentata, near Goshen, Utah, U.S.A.
