Description (from Thorne, 1974)
Body arcuate, especially in posterior fifth where it frequently ends in a ventrally bent or hooked tail. Lip region continuous with neck contour but usually appearing set off because of amphidial openings on the twisted neck. Lips rounded with papillae not interfering with contour. Tooth 8-10 um long, elongate deltoid. Esophagus enlarged near middle by gradual expansion with gland nuclei obscured by dense tissues. Cardiac glands enveloping cardia, not extending out over anterior end of intestine. Intestinal cells packed with dark brown granules. Vulva longitudinal with broad vagina. Ovaries often reflexed almost to vulva. Eggs about 2 1/2 times as long as body width. Prerectum 2 to 3 times as long as body width. Rectum length about equal to anal body diameter.
A single male collected from native prairie sod near Opal, South Dakota. Spicula lightly arcuate resting on a thin trough-like gubernaculum. Supplements sub-mammiform, six in number. Testes not present. Obviously a nonfunctional individual.
Habitat: Widely distributed in both virgin and cultivated soil in Colorado, Nebraska, North and South Dakota, Minnesota and Manitoba and Saskatchewan, Canada.
