Paratylencholaimus Wu, Xu, Xie & Wang, 2019

The genus Paratylencholaimus is considered similar close to Goferus and Phellonema in having simple amphidial fovea, odontostyle without stiffening pieces and the female didelphic. It differs in having the lip region offset, odontophore rod-like (vs. arcuate),the posterior third of the esophagus with a cylindrical basal expansion and the rounded to conoid-round tail. It differs from Tylenholaimus in having a dorylaimoid rather than a tylencholaimoid cuticle.

Cuticle dorylaimoid with fine transverse striations.
Lip region cap-shape, offset from the body.
Amphidial fovea not sclerotized.
Odontostyle straight, tubular with small aperture, without dorsal accessory pieces.
Odontophore rod-like and basal part slightly expanded. Guiding ring simple.
Esophagus slender in anterior part, expanded in the posterior 1/3 of esophageal length.
Tail short, rounded to conoid-round.

Female:

Didelphic-amphidelphis
Vulval lips not sclerotized.

Feeding:

Nematodes in the Tylenchcholaimellidae are generally considered to be fungivores.. However, Wu et al (2019) noted dark intestines in some of the nematodes cultured in a medium of Sphagnum moss and bark, perhaps suggesting feeding on fibrous or cellular material besides fungi (Wu et al., 2019).
