The genus Bathyodontus Fielding, 1950 includes only a handful of described species. Although distributed on all continents (except Australia), it is considered a rare genus, with only one species present in Europe.
Morhologically it is easy to recognize with a small, stout body; an offset head; cup-shaped amphids; a narrow tubular stoma and a broadly rounded short tail including a spinneret. Females are didelphic, males have a great number of supplements. Male are extremely rare.
