Morphology and Anatomy:

This genus consists of a rather heterogeneous group of species and attempts have been made to subdivide them into subgenera.

The muscular sheath surrounding the enlarged basal portion of the esophagus in nematodes of the superfamily Belondiroidea has a very slight spiral in Dorylairnellus aequalis with each muscle band passing around only about 180 degrees of the circumference of the esophagus. The muscle bands completely encircle the esophagus in D. parvulus, and pass around about 3/4 the circumference in D. tenuidens (Hechler, 1969).
