Tylodoridae Tylenchidae is a family of nematodes.

They are an important group of soil dwelling species that frequently contributes as much as 30% to the nematode species richness of soil samples.

[2] They diverged relatively early on and many species pose little risk to economically important plant species.

[2] Due to their early divergence, species tend to have relatively basal characteristics.
