Morphology and Anatomy:

The genus Nothotylenchus was established byThorne for species of Anguinidae with indistinct metacorpus bulb that is not muscular, does not have a valve, andt is not used in active feeding (anguinid species with the median pharyngeal bulb indistinct, non-muscular, non-valvate, and not assisting in active feeding,  (Esmaeli et al., 2016).

Validity of the genus is well established based on morphological, morphometric and molecular data (Siddiqi, 2000; Andr�ssy, 2007, Subbotin and Riley, 2012; Hashemi and Karegar, 2020)

.
  • Median bulb not differentiated, valve lacking. 
  • Deirids present. 
  • Lip region flattened, head frame weak.
  • Stylet delicate.
  • Nothotylenchus is close to Ditylenchus in its general appearance, its esophagus differs in that it has a vallveless underdeveloped metacorpus compared to the well-developed, muscular, valvate metacorpus of Ditylenchus. 
  • Postcorpus pyriform, not ovrtlapping intestine.
 

Female:  Monodelphicl, prodelphic.

Columned uterus with four rows of 4-9 cells. The gonad differs from Ditylenchus mostly in the columned uterus.

Ref: Esmaeli et al., 2017
Males:  When present, with gubernaculum and leptoderan bursa.

Economic Importance:

Only a few species are parasites of higher plants, most are mycophagus (Esmaeli et al., 2017).

Feeding:

Food Sources and Feeding strategies for the genus Nothotylenchus

  Phytoparasitic species are ectoparasites, probably feeding mainly on root hairs. Probably all species can feed on fungi in the absence of plant hosts.
