Morphology and Anatomy:

• Robust nematodes with round head and conical tail,
• Cuticle finely transversely striated.
• Anterior sensilla in three circles (6+6+4).
• Amphidial fovea rounded spiral surrounded by striations (with one exception).
• Cephalic setae at the level of the amphidial fovea.
• Buccal cavity large, cuticularized, with a large dorsal tooth and two small ventrosublateral teeth.
• Pharynx with a pyriform posterior bulb. No secretory-excretory system observed.

Over many years, a considerable number of species have been assigned to and removed from this genus by various authors.
