The identification of females within the subfamily Ostertagiinae Lopez-Neyra 1947.
As a result of the examination of many thousands of female nematodes classified as belonging to the sub-family Ostertagiinae Lopez-Neyra 1947, it became possible to compile descriptions of different female types, each of which corresponds to a polymorphic species as determined by male morphology. The female types have been designated as follows: Ostertagia ostertagi (males O. ostertagi and O. lyrata), Ostertagia circumcincta (males O. circumcincta, O. trifurcata and Teladorsagia davtiani), Ostertagia leptospicularis (males O. leptospicularis and O. kolchida) and Spiculopteragia asymmetrica (males S. asymmetrica and Apteragia quadrispiculata).
