Relatively small nemas 0.5-2.0 mm long.  Bodies usually curved with arcuate tails, rarely straight or subdigitate. Lip region angular, set off by depression or constriction.  Spear aperture occupying 2/5 or less of its length; guideing ring sclerotized. Esophagus usually enlarged near middle by rather abrupt expansion.  Dorsal esophageal gland nucleus close to its orifice.  Cardiac disc variable, present or obscure.  Vulva transverse with sclerotized labia or longitudinal.  Males present for many species, absent in others.  Junction of intestine and prerectum within range of supplements.

Type species: Eudorylaimus carteri (Bastian, 1865) Andrassy, 1959

Recent work by Tjepkema, Ferris and Ferris proved that at least some species of Eudorylaimus are predators and
subsisted on colonies of  Panagrellus redivius.
