Dorylaimellus parvulus
Thorne, 1957
Photo Gallery-Konza Prairie

L= 0.53 mm; a= 25; b= 2.5-3.0; c= 33; V=57

    Body rather cylindrical, almost straight when relaxed by gradual heat.  Lateral cords very narrow with only about 15 pairs of obscure gandular bodies.  Lip region about one-third as wide as neck base, set off by a slight depression.  Generally the head is twisted until amphids appear in profile.  The tiny inner portions of the lips about the vestibule are amalgamated until they frequently appear as a small disc.  Cuticularized pieces about vestibule minute, easily overlooked.  Spear length about equal to width of lip region.  Spear extensions in two sections, the flanges well developed.  Esophagus with the usual elongated swelling a short distance behind the spear, constricting to a very narrow tube as it passes through the nerve ring, then gradually enlarging near the middle.  Cardia cylindroid, one-fourth as wide as body and slightly longer than wide.  Intestinal cells with conspicuous, refractive, dark brown granules.  Ovaries very short, their length less than twice the body width.  Eggs two to three times as long as the body width.  Prerectum five times as long as body width. Tail a little longer than anal body diameter with hemispheroid terminus.

    Diagnosis: Dorylaimellus with the above measurement and general description.  Distinctive because of its small size, long slender spear and very short prerectum.

    Habitat: Frequently collected in small numbers from mountain soils near Salt Lake City, Utah, U.S.A
