Measurements (from Thorne, 1939)
L = 1.9 mm; a = 41; b = 5.2; c = 56; V = 51

Description (from Thorne, 1939)
    Lip region discoid, about half as wide as neck base.  Amphids stirrupform with obscure apertures, one-third as wide as head.  Sensillae about opposite spear base.  Pharynx one-third head width.  Guiding ring extensible.  Esophagus with swellings anterior to nerve ring similar to those of Discolaimus major.  Posterior three-fifths of esophagus enlarged, somewhat irregular in width.  Intestine six cells in circumference.  Vulva transverse.  Vagina extending one-third across body.  Ovaries nearly symmetrical, reflexed two-thirds the distance back to the vulva.  Eggs three to four body widths long.  Lateral cords one-third body width, usually with conspicuous cells connected with the lateral pores.  Tail somewhat longer than anal body diameter, convex-conoid to a blunt terminus.  Male unknown, gravid females contained no sperms
    Diagnosis: Discolaimus with the above measurements and general description.  Closely related to D. major from which it differs in the more slender body, a = 41 : 33, conoid tail and relatively longer eggs.
    A Dorylaimus spear was present in the intestine of one specimen.  Doubtless the species is nemativorous.
    Habitat: In soil collected by Mr. E. W. Davis, U. S. Bureau of Entomology and plant Quarantine, about roots of Covillea tridentata near Littlefield, Arizona, U. S. A.
