Summary

Only nine species of the genus Haemonchus are considered valid, namely, H. contortus (Rudolphi, 1803) Cobb, 1898 (type), H. bedfordi Le Roux, 1929, H. dinniki Sach, Gibbons & Lweno, 1973, H. krugeri Ortlepp, 1964, H. lawrencei Sandground, 1933, H. longistipes Railliet & Henry, 1909, H. mitchelli Le Roux, 1929, H. similis Travassos, 1914 and H. vegliai Le Roux, 1929. These are redescribed.

H. bispinosus Molin, 1860, H. placei Place, 1893, H. cervinus Baylis & Daubney, 1922, H. okapiae van den Berghe, 1937 (in part), H. tartaricus Evranova, 1940, H. contortus contortus Das & Whitlock, 1960, H. contortus cayugensis Das & Whitlock, 1960, H. contortus bangalorensis Rao & Rahman, 1967, H. contortus hispanicus Martínez Gómez, 1968, H. contortus kentuckiensis Sukhapesna, 1974 and H. contortus var. uktalensis Das & Whitlock, 1960 are considered synonyms of H. contortus (Rudolphi, 1803) Cobb, 1898.

The synonymy of H. lunatus Travassos, 1914, H. atectus Lebedev, 1929, H. pseudocontortus Lebedev, 1929 and H. fuhrmanni Kamensky, 1929 with H. contortus is confirmed. H. okapiae van den Berghe, 1937 (in part) is considered a synonym of H. mitchelli Le Roux, 1929 and H. bubalis Chauhan & Pande, 1968 is considered a synonym of H. similis Travassos, 1914.

H. bovis Bonelli, 1941 and H. contortus var. kashmirensis Fotedar & Bambroo, 1965 are considered species inquirendae. An illustrated key to the species of the genus is provided.
