. Circles of six inner and six outer labial setae situated close together on the anterior end, subapically, with a circle of four cephalic setae posterior to the circles of inner and outer labial setae. Amphideal fovea situated between the circles of the outer labial and cephalic setae. Amphideal fovea varies in shape between species and may differ in males and females of the same species: may be ovoid with an anterior round aperture, horseshoe-like or crescent contoured or more complex. An only posterior antidromously reflexed ovary present; vulva shifted anteriorly. Tail never clavate, more or less short, cylindrical or occasionally conical, with rounded tip; terminal caudal capsule absent or weakly developed.
