Summary:Abstract Comparative studies of three species T. circumcincta , T. trifurcata and T. davtiani , which are preliminarily different morphs of the same species, have been carried out in this paper. Insignificant differences in morphological sizes and characters between males were identified and fragments of ITS-2 ribosomal DNA of three species of the genus Teladorsagia were investigated. There were no sequence differences between T. circumcincta and T. trifurcata . Minor differences were noted between T. circumcincta and T. davtiani species at the level of 0.8%. With complete similarity between T. circumcincta and T. trifurcata and a low percentage of differences between T. circumcincta and T. davtiani in different specimens, they represent different morphological forms of one species of T. circumcincta .
