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.
