). With characteristics of the genus. Body moderately robust, cephalic end rounded, cuticle with transverse striations. Posterior part of body often curved ventrally. Narrow lateral alae beginning in cervical region, terminating at anal region. Mouth opening spindle-shaped, with three conspicuous papillae on either side—the central one likely an amphid. Mouth opening bordered by transparent cuticular collarette bearing weak longitudinal rib-like structures (“teeth”). Inner circle of three small papillae present. Two bud-shaped deirids, one on either side, often asymmetrical, adjacent to lateral alae, and posterior to nerve ring. Tail conical, gently tapering, bearing mucron. Hemizonid posterior to nerve ring. Oesophagus muscular, clavate, expanded anteriorly to form pseudobuccal capsule. Bilaterally symmetrical cephalic plates present, separated by narrow sutures and attached to thickened cuticular plates of pseudobuccal capsule (
