Worldwide distributed; reported from more than 50 countries or territories.  According to Andrassy (2009), it "might be the most common soil nematode species" (Presumably he was referring to the subset of nematodes in the Dorylaimida). 

The type locality is Falmouth, England.


  Categorized as predators and omnivores (Yeates et al., 1993; Wood, 1973)
