Morphology and Anatomy:


Females are strongly obese. curved or coiled ventrally when relaxed.  Interestingly, the males cuved dorsally (ventral surface out) when heat relaxed.

Mature females obese.

Economic Importance:

Nematode-induced galls on the grasses Polypogon monspeliensis and Lachnagrostis filiformibecome become colonized by Rathayibacter toxicus which is responsible for posoning of grazing animals.  The condition is known as "flood plain staggers" or annual ryegrass toxicity" ( Bertozzi and  Davies, 2009).

The nematodes induce galls on shoot meristems and in developing seeds.
