Morphology and Anatomy:

Although in a different family of the Cosmocercidea (Atractidae), species of Labeonema are considered to be morphologically very similar to Raillietnema of the family Cosmocercidae. One difference is that females of Labonema are monodelpghic prodalphic while those of Raillietnema are didelphic amphidelphic while the postion of the vulva is near mid body in both (Moravec et al., 2025)
