Morphology and Anatomy:

  • short, thin body,

  • lip region continuous with body contour

  • six lines in lateral field, a short,

  • short thin stylet with minute knobs,

  • pharyngeal glands withlong dorsal overlap of intestine

  • vulva at 89% of body length,

  • ovary long, usually reaching nerve ring, reflexed once or twice in some individuals, oocytes in multiple rows close to the germinal zone, reducing to two rows distally,

  • spermatheca containing sperm

  • short post-uterine sac

Male:

Feeding:

The nematode was not recovered from beetles and whitegrubs in the bark of dead trees so entomoparasitic forms are uncertain.

Yaghoubi et al (2019) suggest since the nematodes were recovered from bark samples and have a delicate stylet, members of the genus Anguillonema amay be fungus feeders; however, culturing experiments have not been conducted.
