Durikainema is a genus of two nematodes in the family Robertdollfusiidae. Species have a head with a cuticular cephalic inflation, elongated papillae and amphids, and well-developed musculature. Characteristics of the males include a single spicule and a long attenuated tail. Durikainema species parasitize macropods. The genus was circumscribed in 1982 with the type species Durikainema macropi,[1] a parasite of the eastern grey kangaroo (Macropus giganteus). D. phascolarcti, parasite of the koala (Phascolarctos cinereus), was described in 1998.
