Morphology and Anatomy:

• Body stout, partly coiled, slender at anterior end.
• Cephalic collar distinct, with 4 tiny conical submedian papillae and 2 amphids.
• Cervical cuticle inflated into distinctive vesicle extending from cephalic collar to level of nerve-ring and excretory pore.
• Mouth opening circular with 4 teeth  within buccal capsule in sub-median positions, projecting through mouth opening; between teeth are  small denticles, arranged in pairs on dorsal and ventral aspects, in triads on lateral aspects
•  Buccal capsule refractile, heavily sclerotized, cylindrical, about as long as wide, with thin walls anteriorly becoming thicker posteriorly
• Dorsal gutter runs within wall of buccal capsule to level of dorsal knob, then runs as canal on internal surface of buccal capsule, forming a ‘Y’  then running posteriorly to mid-level of buccal capsule on ventral surface.
• Esophagus simple, claviform, with thickened lining; anterior ends projecting into lumen of buccal capsule as esophageal teeth. Nerve-ring and excretory pore in anterior 20% of esophagus.
• Two prominent lateral alae arise at level of nerve-ring, extend along most of body. Deirids small, sub-conical, project from alae near their commencement.

Male:

• Spicules simple, elongate, alate; proximal extremities irregularly knobbed; distal tips simple, blunt;
• Ala terminates close to spicule tip.
• Gubernaculum ovoid; central cordate and lateral paired thickenings of spicule sheaths present.
• Genita cone with anterior lip conical; posterior lip with 2 low projections; 5 conical lobes surrounding posterior lips

Female:

• Vulval close to anus and tail tip
• Vagina short, straight, or twisted to one side, enters muscular, Y-shaped ovejector; sphincters short, muscular; infundibula slightly longer than sphincters, less muscular.
• Egg thin-shelled, ellipsoidal.
