Morphology and Anatomy:

•  Body slender, sigmoid;
• Swollen pharyngeal region 8-6.4% of total body length.
• Cuticle with vacuolar ornamentation at level of pharynx, on slender body region posterior to pharynx, at level of testis, and around cloacal opening.
• Cuticle at mid-body interrupted by a more or less conspicuous lateral field.
• Ten or twelve ccephalic adhesion tubes with widened base and slightly enlarged tip, located either on head capsule or posterior to amphidial fovea within a distance of one head capsule width.
• Amphidial fovea loop-shaped or consisting of an inner and an outer loop in males, spiral in females and juveniles.
• Anterior part of pharynx cylindrical, with elongated, muscular terminal bulb and with or without less pronounced anterior swellings around mid-corpus and/or at level of head capsule. Terminal bulb of pharynx without thickened lumen wall.
• Buccal cavity short and narrow, without teeth.
• Tail with numerous annules.
