See text Dorylaimida (dorylaims) is a diverse order of nematodes[1] with both soil and freshwater species.

[2] The order originated with the description of Dorylaimus stagnalis by Dujardin in 1845, and in 1876 De MAn proposed the family Dorylamidae, while Cobb added many other genera and subgenera.

Other reclassifications include Jairajpuri (1964, 1969, 1976, 1980, 1983, 1992), Thorne (1964, 1967), Siddiqui (1968, 1983), Andrássy (1969, 1976), and Coomans and Loof (1970).

The scheme shown here is that of Jairajpuri (1992), which excludes the mononchs, alaims (Alaimida) and diphtherophorids (Triplonchida).

[2] The families of order Dorylaimida are divided into three suborders and a number of superfamilies:[2][3]
