Bodies of both sexes slightly arcuate, tails usually bent ventrally. Lateral field about 1/3 as wide as body. Lip region slightly angular set off by depression. Spear 16-18u long, the aperture occupying 1/2 its length. Pharynx about 1/3 head width with refractive guiding ring. Esophagus enlarged near middle by gradual expansion. Cardia elongated with details as illustrated. Vulva longitudinal with vagina as illustrated. Egg slightly longer than body width. Ovaries reflexed about halfway to vulva. Prerectum slightly longer than body width, with short posterior extension. Male with 13-16 closely spaced supplements. Spicula arcuate with strong ventral angle and bent guiding pieces. Tails of both sexes arcuate, acute.
Habitat: Cultivated fields, Gary, Huron, Aberdeen and native
sod, Cottonwood, Bear Butte and other points in South Dakota. Native

This species resembles Dorylaimus carteri but is readily distinguished
by its relatively shorter tail, by the supplements which begin just opposite
the anterior end of the spicula, and by the spear which has an aperture
occupying one-half its length. Esophagus enlarged near middle until
two-thirds the neck width; cardia elongate-conoid; female rectum and prerectum
each slightly longer than anal body diameter. Ovaries reflexed about
two-thirds the distance back to the vulva; lateral cord one-sixth the body
width; supplements 14-18 separated by spaces about twice as wide as the
Measurements and figures given are from specimens collected near Ogden, Utah. The type specimens from Holland have a slightly longer esophagus, 29 per cent, and vulva farther back, 58 per cent of total length
Habitat: Small numbers from stream bank soil collected at various
points in the Wasatch and Uintah Mountains, U.S.A. Reported from
many localities in Europe.
