could be only a provisional solution. In addition, we want to state that in the material of tapeworms deposited in the Muséum Histoire Naturelle, Geneva, there are tapeworms of rodents of a character given in this study for the genus Andrya. We received a similar communication from HAUKISALMI and HENNTONEN (1986) on material from Finland. In this sense it is necessary to carry out further detailed studies (compare our paper and SCHMIDT, 1986). KEY FOR THE IDENTIFICATION OF THE SPECIES OF THE GENUS ANDRYA RAILLIET, 1893 1. Uterus not beyond ventral excretory canals, testes in poral part of segments not across level of poral part of ovary (Fig. 5) Andrya rhopalocephala (Riehm, 1881) 2. Uterus beyond ventral excretory canals, testes in the poral part of segments beyond level of poral part of ovary (Figs 3 and 4) Andrya cuniculi (Blanchard, 1891) II. HISTORY OF THE GENUS PARANOPLOCEPHALA Lühe, 1910 The history of the above-mentioned genus has been discussed at great lengths in several papers (see RAUSCH, 1976; TENORA, MURAI and VAUCHER, 1984, 1986). A completely new opinion about the position of the genus Paranoplocephala given in the above-mentioned study was due to two fundamental facts: - The main one is in the finding of RAUSCH (1976) that: "A comparison of P. omphalodes with A. macrocephala from rodents in North America has revealed no morphological differences that I consider to have taxonomic significance at the generic level. " It was also RAUSCH (1976) who was the first to note that Aprostatandrya Kirschenblat, 1938 is a synonym of Par anoplocephala Lühe, 1910. - The second fact is an important communication from TENORA and MURAI (1980), and later from TENORA, VAUCHER and MURAI (1981-1982) reporting that the species P. omphalodes has a network-like uterus. Due to the above-mentioned facts the genus Paranoplocephala was transferred into the subfamily Monieziinae. Thus an opinion which had lasted for more than half a century was revalued, a tradition about the character and development of the uterus of the species P. om phalodes which had perpetuated in all the generally used journals (compare e.g. BAER, 1927; JOYEUX and BAER, 1936, SPASSKY, 1951; LOPEZ-NEYRA, 1954; YAMAGUTI, 1959; TENORA, 1976). The studies of RAUSCH, 1976; TENORA, VAUCHER and MURAI (1981-1982); TENORA, MURAI and VAUCHER (1984, 1985) give more detailed data about this problem. The authors further present a diagnosis of the genus Paranoplocephala Lühe, 1910 and the species structure of this genus. Contrary to SCHMIDT (1986) they range in Paranoplocephala wide spectrum of species. Paranoplocephala Lühe, 1910 Syn. : Aprostatandrya Kirschenblat, 1938 Diagnosis: After RAUSCH (1976) emend. Monieziinae Spassky, 1951. Strobila of medium size with numerous segments sometimes small. Segments usually wider than long, with relative length increasing posteriad, usually wider than neck. Scolex usually with prominent, motile suckers. Excretory system simple, with dorsal and ventral canals bilaterally, with posterior anastomose. Genital pores unilateral or irregularly alternating, sometimes in sets. Genital ducts passing dorsal to excretory canals. Vagina opening posterior to orifice of male duct. External and internal seminal vesicle present. Testes numerous, distributed a) aporally, b) aporally and anterior to ovary, c) anterior between the ventral excretory canals or beyond these canals, d) aporally, anterior and porally to ovary. Uterus first mucose, ventrally (anteriorly) later transversally, forming an aggregation which gradually pushes back the testes
