Examination of the Validity and Systematic Position of Some Paramphistomids of Indian Ruminants Dr. Ottó SEY Department of Zoology, College of Education, Pécs "Examination of the validity and systematic position of some Paramphistomids of Indian ruminants" - Sey, O. - Parasit.Hung. , 12. 31-36. 1979. ABSTRACT. The author examined the validity and the occurrence of a group of species of amphistomes in India and came to the conclusion that Paramphistomum epiclitum Fischoeder, 1904 (synonyms: Cotylophoron indicum Stiles et Goldberger, 1910; P. thapari Price et Mcintosh, 1953; Srivastavaia indica Singh, 1970), P. gra cile Fischoeder, 1901 (synonyms: P. indicum Stiles et Goldberger, 1910; P. cervi of several Indian authors; P. ichikawai of Gupta and Nakhasi, 1977) and Orthocoe- lium giganthopharynx (Schad, Kuntz, Anteson et Webster, 1964) (synonym: P. gotoi, of Tandon, 1955) are valid. The examination of amphistomes of Indian ruminants has been made for more than a century, during which several papers and general works have dealt systematically with the problems of these helmints. Opinions, however, vary concerning the validity and occurrence of certain species in India. The reason of these different opinions may lie in the absence of re-examination by newer methods of species, as the ones described earlier were mainly done on the basis of gross-morphological and anatomical features. Therefore recent descriptions of species by helminthologists of India have been done without clarifying the actual systematic position of some obscure species. Misinterpretation of features and nomenclature in case of histo-morphologically examined species led also to erraneous conclusions. These circumstances did not only increase difficulties in identification but also disturbed the interpretation of the characteristic features of the amphistome fauna of East India. The present paper comprises species Cotylophoron indicum Stiles et Goldberger, 1910; Paramphistomum cervi (Zeder, 1790); P. epiclitum Fischoeder, 1904; P. gotoi Fukui, 1922; P. ichikawai Fukui, 1922; P. thapari Price et Mcintosh, 1953 and Srivastavaia indica Singh, 1970. This group of species includes a certain part of amphistomes which were often discussed. Materials and Methods In 1977/78 a collection of amphistomes was obtained by the author in different Indian slaughter houses (Alîgarh, Bareilly, Delhi, Lucknow, Calcutta), research institutes (Indian Veterinary Research Institute, Izatnagar; Zoological Survey of India, Calcutta) and universities (Allahabad, Calcutta, Chandigarh, Gujarat, Guntur, Luthiana and Mathura). Besides these it was possible to examine several toto mounts and some median sagittal sections of amphistomes deposited in the Zoological Survey of India, Calcutta and the Zoological Department, Panjab University, Chandigarh. Flukes removed from rumina were fixed and preserved in 70 per cent alcohol or 2-3 percent formalin. Median sagittal sections and toto mounts were prepared by the usual methods. About one hundred sections and some preparations of the type specimens of C. indicum,
