1.1 mm; a = 39; b = 5.0; c = 25; V = 50
Body less cylindrical
and much more arcuate than in the other known
twisted until a true lateral view of the head
is difficult to obtain. Posteriorly it tapers uniformly to the dorally
convex-conoid, arcuate tail.
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
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.,
