Abbreviations; An, anus; BC, buccal capsule; BR, basal ring; Ca, caudal alae; Cl; cloaca; GO, glandular oesophagus; In, intestine; MO, muscular esophagus; Mo,stoma; NR, nerve ring; Ph, phasmid; Pr, proctodeum; Re, rectum; Ta, tail. (adapted from Khalifa et al., 2019).

Llive specimens; reddish fixed specimens yellowish brown.
Medium-sized nematode, finely transversely striated cuticle,
Stoma circular, dorso-ventrally elongate, surrounded by thin translucent membrane with six flat, crescent-shaped elevations and four submedian cephalic papillae
Small lateral amphids behind papillae.
Buccal capsule sclerotized, thick-walled, barrel shaped, with well-developed basal ring; basal, narrowed part of buccal capsule proper anterior to basal ring somewhat thickened.I nner surface of capsule smooth, without spiral ridges
Esophagus in two parts; anterior muscular portion club-shaped and posterior glandular portion elongate, ending with paired bilobed valves.
Nerve ring situated at the end of first third level of muscular esophagus or at the beginning of its second half.
Excretory pore posterior to junction of esophageal parts.
Tail of both sexes conical.
