Hung. 13_. 39-57. 1980. ABSTRACT. A new systematic division of cestodes of the suborder Catenotaeniata Spassky, 19 63 is presented. The single family Catenotaeniidae Spassky, 1950 belong­ing to this suborder is divided into two subfamilies: Catenotaeniinae Spassky, 1949 and Skrjabinotaeniinae Genov et Tenora, 1979. The subfamily Catenotaeniinae in­cludes the genera Catenotaenia Janicki, 1904, Hemicatenotaenia (Tenora, 1977) Genov et Tenora, 1979, Pseudocatenotaenia gen.nov. and Quentinotaenia gen.nov. The subfamily Skrjabinotaeniinae comprises the genus Skrjabinotaenia Akhumyan, 1946 and Meggitina Lynsdale, 1953. A hypothesis on the evolution of cestodes of the suborder Catenotaeniata is discussed. INTRODUCTION The suborder Catenotaeniata was established by SPASSKY (19 63) for the cestodes of the family Catenotaeniidae Spassky, 1950. The separation of this family from the suborder Anoplocephalata was necessary with respect tó its morphological-anatomical characters, dif­ferent process of evolution, specialization (during the life-cycle) to invertebrates and to a single order of mammals - rodents. Characteristic features of the larvae of these cestodes are the presence of the apical sucker. In adult specimens, the topography of body organs is arranged in a quite special manner: originally strong asymmetrically formed ovary (except Quentinotaenia ) and originally markedly elongated uterus (except in Meggittina) . FREEMAN (19 73) pointed out independent evolutionary branches of cestodes of the families Catenotaenii­dae, Proteocephalidàe and Taeniidae (which according to SPASSKY, 1978 are taxa at the level of suborders: Catenotaeniata, Proteocephalata and Taeniata) and documented a principal dif­ference between the evolution of these cestodes and of those of the family Anoplocephalidae (Anoplocephalata). Thus, the scheme of FREEMAN (1973) is near to the classification of LOPEZ-NEYRA (1947) who included already the genus Catenotaenia in the family Taeniidae. In spite of the above facts the system proposed by SPASSKY in 1963 has not been generally accepted in the helminthological literature. Often the family Catenotaeniidae has not even been recognized and the species of this family have been ascribed to the subfamily Catenotaeniinae or Anoplocephalinae (fam.: Anoplocephalidae) belonging to the suborder Ano­plocephalata (see GENOV and TENORA, 1979). Our studies of the material (see below) and literature revealed that with regard to the present state in the cestode taxonomy, Catenotaeniidae can be placed as a single known family to the suborder Catenotaeniata. On the other hand, the studies of the peculiarities of these cestodes, not only from morphological, but also ecological and paleobiological view­points, let us to the conclusion that the present system of Catenotaeniata should be revised. MATERIAL The material mentioned by GENOV and TENORA (1979) and original material from Spain and Hungary were used for the present studies:
