Morphology and Anatomy:


 

Morphological characters considered intermediate between those of Deladenus and Hexatylus, hence the name.

Female:

  • Body ranging from vermiform to semiobese and from straight to dorsally curved.
  • Lateral fields raised.
  • Lip region moderately high, continuous with body contour.
  • Head with six sectors; four submedian and two smaller and lateral.
  • Oral aperture elongate.
  • Stylet tylenchoid with three distinct knobs sloping posteriorly; cone slightly shorter than  shaft, with 4 to 5 guiding rings (one or two on the cone, three always on the shaft).
  • Esophagus neotylenchoid: without a median bulb, and glands free in the body cavity; pharyngo-intestinal junction located immediately posterior to the nerve ring.
  • Excretory pore posterior to the nerve ring.
  • Intestinal lumen widening immediately after the esophago-intestinal junction; rectum broad.
  • Female reproductive system of monodelphic, prodelphic; spermatheca apparently absent; vulva a transverse slit.
