Feeding:

 Parasites of the  coelomic cavities of terrestrial oligochaetes of the superfamily Megascolicoidea. It predominates in pheretimoid oligochaetes native to South–East Asia and Australasia. Several pheretimoid earthworm species (Amynthas leucocircus, A. lignophilus, A. mucrorimus)  are particularly susceptible to invasion of drilonematids and are hosts to several genera and families of nematode parasites (Spiridonov & Ivanova 2005)
