Morphology and Anatomy:

Body length 2.2-2.5 mm
Cuticle of two layers.
Labial region offset from body contour by distinct constriction.
Odontostyle short and thick; aperture typically 73-77% of odontostyle length.
Odontophore rod-like; guiding ring simple.
Basal expansion of esophagus about half of total length.
Female gonad diovarial, amphidelphic; vulva transverse.
Vaginal canal a simple tube, sclorotized pars refringens vaginae present.
Tail similar in both sexes; short, conoid with rounded terminus, longer than anal body diam (abd).
