Diagnosis
Nygolaimidae , Nygolaiminae . Small- to large-sized nematodes, 0.7–3.7 mm long. Cuticle dorylaimoid. Lip region continuous with the adjoining body (but very exceptionally offset), often asymmetrical, truncate or somewhat cap-like, with fused lips and low papillae. Amphid fovea cup-like, its aperture barely less than one-half of the lip region diameter. Mural tooth linear, about as long as lip region diameter. Guiding ring weak, plicate. Pharynx entirely muscular, enlarging gradually, the basal expansion surrounded by a weak but perceptible sheath and often occupying more than half (up to three-fifths) of neck length. Cardiac cells conspicuous, rounded to ovoid. Female genital system diovarian, with simple uterus, absence of pars refringens vaginae and transverse vulva. Tail similar in both sexes, convexconoid to nearly hemispheroid. Most species bisexual. Spicules dorylaimid. Gubernaculum present. Ventromedian supplements 2–7 in number, irregularly spaced, with hiatus.
