Belondiridae

The Dorylaimida family Belondiridae Thorne, 1939 includes two subfamilies (Axonchiinae Thorne, 1964 and Belondirinae Thorne, 1939) and a total of 18 genera, o.a. Axonchium Cobb, 1920 and Syncheilaxonchium Coomans & Nair, 1975.

Typical for this family is the absence of sclerotized pieces around the oral opening and the presence of a non flanged rod-like odontophore and a short tail in both sexes. They are mostly soil dwellers with a few taxa found in aquatic habitats and can be found world-wide.
