The genus name possibly reflects the ventarl toot located deep in the stoma.
|
The genus Bathyodontus is distinguished by the ventral tooth
located at the base of the stome, and the axial terminal pore at the
tail tip. It resembles genus Oionchus in the cylin droid
body and esophagus, and the axial terminal pore. |

 |
- Body cylindrical from the middle of the neck to a short distance
in front of the anus.
- Lips amalgamated, practically continuous with the neck contour,
bearing an inner circlet of six and an outer circlet of ten
papillae.
- Conspicuous, granular lateral cords are about 1/3 the body width
except at the extremities.
- Amphids small, cup shaped.
- A single ventral tooth is located at the base of the cylindroid
buccal cavity.
- Five esophageal glands.
- Cardia large, irregularly shaped.
- Tail hemispherical with a terminal an axial pore,which
probably has a a spinneret-like function.
Female:
- Didelphic, amphidelphic, ovaries reflexed
- Vulva a transverse slit
