Morphology and Anatomy:

• Robust nematodes
• Ccuticle with transverse striations.
• Mouth opening simple, hexagonal, encircled by six leaf-like elements separated by six small pointed elements, arising from internal surface of buccal capsule.
• Buccal region comples with an anterior cavity circular.followed by a proximal pharygeal portion,.
•  The posterior part of the buccal comples is formed by lobes of the esophagus that extend anteriorly to form a pharyngeal extension between the true buccal capsule and the esophagus, The proximal lobes of the  pharyngeal extension are sclerotized, the radial and chordal lobes erect, distinct, slightly muscular. The chordal lobes are are ornamented with numerous irregular teeth.
• Esophageal corpus cylindrical with distinct isthmus, esophageal bulb slightly wider than long;
