Eudorylaimus confusus
Thorne, 1974
1.2 mm; a = 26; b = 3.4; c = 31; V = 63
Body practically striaght. Lip region angular, set off by constriction.
Lateral field 1/4 body width. Spear 17u long with aperture
occupying 1/3 its length. Esophagus enlarged near middle by rather
abrupt expansion. Esophageal glands arranged similar to those of
Aporcelaimellus,
the anterior pair being separated by a distance about equal to width of
esophagus. Very little evidence of a cardiac disc, the cardia elongate-conoid
with intestinal cells almost conpletely surrounding it. Vulva longitudinal
with moderately sclerotized labia. Vagina cylindroid, extending half
way across width. Ovaries reflexed half way to vulva. Eggs
1 1/3 times as long as body width. Prerectum slightly longer than
body width, sometimes with a slight posterior extension. Tail with
a very slightly digitate bluntly rounded terminus. Cuticle of tail
with easily seen radial striae. Males not collected.
Eudorylaimus confusus is distinguished by Eudorylaimus-like
spear and rather abruptly expanded esophagus and by the Aporcelaimellus-like
arrangement of the anterior pair of esophageal gland nuclei. Also
the bluntly rounded, subdigitate terminus.
Habitat: A widely distributed species from cultivated,
prairie and windbreak soils from Boulder, Colorado to Hadashville, Manitoba,
Canada.
