region about one-fourth as wide as neck base. Cuticle conspicuously
thick especially at the anterior end. Lateral cords about one-twentieth
as wide as body. Amphids encircling base of lips, forming a deep
pocket. Sensillae located a distance from anterior end equal to about
three times the lip width. Spear
length equal to width of collar surrounding lip region. Aperture
occupying about one-third of the spear length. Anterior portion of
esophagus with a slight, elongate swelling anterior to nerve ring.
Esophagus enlarged in posterior two-thirds, set off by a short isthmus.
Conspicuous spiral muscles surround the basal
portion of the esophagus. Cardia elongateclavate. Granules
of intestinal cells fine, brown, scattered. Female prerectum length
about four times body diameter; rectum length one and one-half times anal
body diameter. Male prerectum extending slightly past supplement
series. Anterior uterus normal but ovary
rudimentary like that of Axonchium serpens. Posterior ovary
reflexed about half way to vulva.
Supplements 17, not contiguous, occupying a space equal to about four and
one-half times the body diameter, the posterior one located close to the
adanal pair. About twenty presupplementary glandular organs extend
to a point opposite the anterior end of the testes.
Diagnosis: Axonchium with the above measurements and general description. The species is conspicuous because of the thick cuticle, deep amphidial pocket completely surrounding the lip region and the number and arrangement of the supplements.
Habitat: One male and two females from soil about roots of quaking aspen, Populus tremuloides, City Creek Canyon, near Salt Lake City, Utah, U.S.A.
