Spirocercidae Chabaud, 1975

Parasites of Vertebrates: Stomach parasites of mammals, birds and reptiles - reported from lizards, cats, dogs, birds, rodents, cougars and others.

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.
