Body cylindroid except at extremities. Striae about 2u apart throughout most of body. Lateral fields with 3 incisures. Head unlike that of any other aphelench with 6 rounded lips bearing a sclerotized basin-like structure. Cheilorhabdions forming a sclerotized spear guide. Spear 32u long without basal knobs, its muscles attached to a sclerotized collar of cuticle, not to cephalic arches. Esophageal bulb longer than neck width, with valve in posterior position. Isthmus shorter than neck width. Excretory pore about opposite nerve ring. Hemizonid 5 annules back of pore. Ovary outstretched with oocytes in single file, sometimes extending to median bulb. Posterior uterine branch composed of a few degenerate cells. An egg was 23u x 87u and contained a developing larva, indicating that the species may be viviparus. Tail dorsally convex-conoid to small elongate terminus.
Considerable variation occurs in tail annulation, sometimes fine annules extending almost to terminus. No annules near lip region, differing from type specimens from Utah which had minute annules extending to lip region. However, these minor differences are considered as geographical variants and not of specific rank.
