Desmodorida (lat.) - a detachment of roundworms from the class Chromadorea [1] . There are free-living marine forms, less often freshwater or soil. Cuticle with ringing (sometimes with scales, sclerotia). The head cuticle forms the head shell, differing in structure (it is smooth) from the rest of the body. Amphids are round or spiral. The head tangoreceptors are located in 3 or 2 circles (the first and second circles in the form of papillas, the second and third with bristles). Spicules and genital tubes of females are paired. Pharynx with a bulb [2] [3] .
