Syn.: Dorylaimus eudorys Ditlevsen, 1911
Measurements (from Thorne, 1974)
L = 5.4 mm; a = 64; b = 5.6; c = 100;
L = 6.5 mm; a = 68; b = 5.8; c = 117; T = 51
Description (from Thorne, 1974)
Body
slightly
arcuate posteriorly. Lateral field about 1/4 body width. Cuticle
about 8 um thick near head. Lip
region typical. Spear
21 um long with aperture 3/4 its length. Basal 2/3 of esophagus enlarged
by gradual expansion. Prerectum of young female 3 times body width,
that of male extending forward almost to end of supplement series.
Supplements 12, rounded, irregularly spaced. Spicula with distinct
ventral angle. Lateral guiding piece only 25 um long.
A single male and two immature females from forest
nursery soil west of Brookings, South Dakota. Collected by R. B.
Malek.
Tails of these specimens are slightly longer and
cuticle thicker than those reported from Utah. Form of spicula, short
gubernaculum and conoid tails distinguish them from other species in the
area. A. amphidysis, Anderson, 1996 differs in thinner cuticle
and form of spicula and gubernaculum. One specimen was infested by
a species of Duboscquia, probably D. penetrans.
