Classification:

Refer to the subfamily Sectonematinae for a discussion of the placement of this family in the Aporcelaimidae rather than the Nygolaimidae.

Morphology and Anatomy:

• Large Nematodes 2.5-5.5 mm.
• Thick cuticle
• Lip region varied, continuous with bodu contour or strongly offset.
• Mural tooth on ventral wall of stoma.
• Stoma with rasp-like region of denticles.
• Esophagus with disc-like cardia.
• Tail in both sexes short and hemispherical.

Nygolaimium strongly resembles Scapidens but is distinguished by the denticle region of the stoma and presence of a cardia disk (Andrassy, 2009).
