Description (from Thorne, 1929)
Characters somewhat similar to Aphelenchus parietinus
Bastian but with these differences: Body only .31 mm in length. Spear
much larger with distinct trilobed base. Tail ending in a mucro formed
by a sudden contraction of the terminus.
The transverse striae are exceedingly fine, being
scarcely visible. There are two very indistinct wings. The
lip region is set off and has a cutinous framework about the entrance to
the pharynx. A narrow vestibule reaches half the spear length, at
its base forming an indistinct guiding ring for the spear. The median
bulb is as long as the neck width and almost as wide as the body cavity
with a conspicuous valvular apparatus near its center. The nerve
ring encircles the narrow tube leading from the bulb to the intestine one
body width below the bulb. The renette pore is opposite the nerve
ring. The anus is distinct and from it the slender rectum extends
forward two anal body-widths. A prominent feature is a ventral narrowing
of the body just posterior to the elevated vulva. The anterior ovary
is out-stretched the posterior rudimentary and only three body-widths long.
Eggs are three times as long as the vulva body-width and fill the body
Five specimens, all of which are adult females.
