Long subcephalic (cervical) setae, arranged in six or eight groups about the level of the amphids, at some distance posteriorly to the cephalic capsule. In each group several subcephalic setae arranged in a short longitudinal row where the setae gradually increase in length posteriorly. Other somatic setae can be short or very long, scarce or abundant, and irregularly distributed along the body. Amphideal fovea circular, just before, just behind or at the level of subcephalic setae. Buccal cavity conical. Copulatory apparatus variable in shape. Tail conico-cylindrical, consisting of proximal conical and slender cylindrical distal parts.
