Ref. Andrassy, 2009, 2011.



  • Female diovarial, amphidelphic;
  • Vulva a longitudinal slit with sclerotized lips or pore-like..


  • Males common in some species, unknown in about 40% of species.
  • Dorylaimoid spicules. 
  • Ventromedian supplements contiguous, 14 to 36.

Feed as predators on other nematodes.  Classified as predator and omnivore by Yeates et al. (2009).

Wood (1973) observed Labronema sp. feeding and reproducing on algae and moss in tissue culture.
