Morphology and Anatomy:

• Body cylindrical; tapering toward tail.
• Cuticle coarsely annulated along body except for smooth region at anterior end and tail terminus; annules widest at mid body and with longituinal striations.
• Somatic pores and lateral alae absent
• Cuticular plate underlying cuticle around amphids
• Cephalic sensilla setiform.
• Amphid fovea an inverted hook-shape; amphidial shield between branches with crenate edges.
• Stoma very small.
• Pharynx with wide cylindrical muscular corpus, narrow isthmus and small, globular basal bulb.
• Excretory pore ventral to pharyngeal bulb.
• Tail subcylindrical, caudal glands opening through 3 separate pores.
• No spinneret.
