Some significant species are Haemonchus placei (in cattle, sheep, and goats), Haemonchus similis (in cattle and sheep), and Haemonchus contortus, the stomach, barberpole, or twisted wire worm of cattle, sheep, goats, and other ruminants, of which a few cases have been reported from humans; accidental parasite of humans.

Haemonchus bedfordi
found in African buffalo and some gazelles.
Haemonchus contortus
found in the abomasum of most ruminants and the cause of serious losses in sheep from haemonchosis. There have been attempts to subdivide the species, e.g. H. contortus cayugensis, but the differences between the subspecies have not been substantiated.
Haemonchus dinniki
found in gazelles.
Haemonchus krugeri
found in impala.
Haemonchus lawrenci
found in duiker.
Haemonchus longistipes
found in camel, dromedary.
Haemonchus mitchelli
found in gazelle, eland, oryx.
Haemonchus placei
the parasite of cattle which can cause hemonchosis in that species.
