Tylencholaimus sp.

In the Netherlands, the genus Tylencholaimus is represented by eight species. It are relatively small nematodes, usually they reach one millimeter in length. The picture shows a female head. Tylencholaimus can easily be recognized by the offset lip region and the spear, with a broadening at its basis. This broadening serves to adhere the muscles which protrude the spear.

In general Tylencholaimus species live in sandy soil although they also occur in freshwater. Tylencholaimus can be easily cultivated on fungi and we assume, that in the soil, their main diet is fungal material. Tylencholaimus and relatives are sensitive to pollutants, their presence in the soil is a good sign.
