Annules of cuticle 1u to 1 1/2u wide. Lateral field a bright band 1/5 body width with traces of 2 incisures. Amphid apertures diagonal, not transverse as usual. Spear 10u-12u long with strong sloping knobs, their muscles attached to a cuticularized band. Dorsal esophageal gland outlet about 7u behind spear. Median bulb about middle of esophagus. Basal bulb elongate, pyriform. Cadia discoid, 1/3 body width. Ovary outstretched with oocytes in single file except for a short region of multiplication. Spermatheca slightly longer than body width.Vulva-anus distance slightly less than length of filiform tail. Terminal portion of the tail often broken off or destroyed by desiccation. Phasmids distinct, 2 or 3 anal body diameters posterior to anus.
     Male more slender than female with well developed bursa. Spicula 30 u long. Gubernaculum thickened, not linear.
    Basiria graminophila is distinctive because of oblique amphid apertures, longer posterior portion of esophagus and longer tail. This species was described from India. The Nebraska specimens vary in having less distinct lateral incisures and slightly longer posterior portion of the esophagus.
     Habitat: Heavy clay soil about roots of various shrubs and trees in river valley 2 miles east of Wauneta, Nebraska.
