Photo Gallery- Konza Prairie

1.1 mm; a = 39; b = 5.0; c = 25; V = 50
Body less cylindrical and much more arcuate than in the other known Discolaimium, usually twisted until a true lateral view of the head is difficult to obtain.  Posteriorly it tapers uniformly to the dorally convex-conoid, arcuate tail. Lips half as wide as neck base, set off by deep constriction and somewhat higher in proportion to width than those of other species.  Spear about as long as width of lip region, the aperture occupying about half its length.  Esophagus enlarged in its posterior three-fifths by a rather sudden expansion, similar in details to the two preceeding species.  Ovaries reflexed half way to vulva.  Vagina similar to that of the type species.  Rectum about as long as anal body diameter, prerectum twice length of rectum.  Males unknown.
Diagnosis:  Discolaimium with the above measurements and general description.  Easily recognized by the higher lip region, by the arcuate, posteriorly tapering body and by the elongate-conoid tail.
Habitat:  Five females from a cultivated field, Fort Collins, Colorado, one of which was observed feeding on a Rhabditis larva.  A single female from soil, about underbrush at an elevation of 7,500 ft., Mt. Wolverine, near Salt Lake City, Utah, U.S.A.
