TAXONOMIC CLASSIFICATION OF THE CESTODE ORDER CYCLOPHYLLIDEA VAN BENEDEN IN BRAUN 1900

A modern taxonomic structure of the cestode order Cyclophyllidea has been developed, with 7 suborders, 25 families and 27 subfamilies being considered as valid. Corrections to the taxonomic rank and authorship of some families have been made. An analysis of literature data concerning modern molecular genetic studies on .the taxonomy has been performed. The positions and validity of such groups as Tetrabothridea and Mesocestoididae are discussed. The most characterisitc morphological traits of each suborder of the helminthes included in this order are given: Acoleata Skrjabin 1940, Anoplocephalata Skrjabin 1933, Davaineata Skrjabin 1940, Hymenolepidata Skrjabin 1940, Mesocestoidata Skrjabin 1940, Taeniata Skrjabin et Schulz 1937, Nematotaeniata Spassky 1958.
