Durikainema
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", a parasite of the eastern grey kangaroo ("Macropus giganteus"). "D. phascolarcti", parasite of the koala ("Phascolarctos cinereus"), was described in 1998.
