A nematode family
of intestinal parasites of vertebrates with arthropods as intermediate hosts
Chabaud (1975) separated the family Spirocercidae from the Spiruridae on the basis of the buccal capsule being laterally flattened in Spiruridae but not in Spirocercidae,, the mouth being dorso-ventrally elongate in the Spiruridae but hexagonal in the Spirocercidae, and the absence of teeth the buccal capsule of Spiruridae but generally present in Spirocercidae.
