12. Paranocephala microti (Hansen, 1947) Tenora, Murai eg Vaucher, 1984. Syn.: Andrya microti Hansen, 1947, Aprostatandrya microti (Hansen, 1947) Spassky, 1951. Original host: MJcr^£u^j^c^r^£a_sJe_r, North America. Holotype: deposited in the Helminthological Collection of the U. S. National Museum. Comments: The species is extremely close to the species P. omphalodes from which it differs only in a smaller number of testes. However, the species P. microti is even closer to the species P. caucasica

. RAUSCH (1948) states: "Since A. microti and A. caucasica are so similar morphologically, and since both are parasites of voles, the possibility of their specific identity should be considered. " The same results are in RAUSCH and TINER (1949). We do not exclude that P. microti and P. caucasica are synonyms of P. omphalodes. 13. Paranoplocephala kirbyi Voge, 1948. Original host: MJ;Çr^u^j^lifojnij:us_, North America. Holotype: deposited in the Helminthological Collection of the U. S. National Museum. Comments: This species is very close to the species P. microti and P. caucasica. VOGE (1948) had not known the study of HANSEN (1947) and that is why she did not give the characters distinguishing the species P. kirbyi from P. microti. It is also interesting that, the similarly to the species P. caucasica and P. microti, VOGE in 1948 found such individuals in the P. kirbyi population which had a tendency to have one-sided genital openings, as well as ir jividuals with alternating genital openings, mostly in sets. RAUSCH (1952) relates the species P. kirbyi with P. macrocephala. However, according to our opinion the species P. kirbyi fundamentally differs from the species P. macrocephala in the distribution of the testes. We do not exclude that the species P. kirbyi is only one form of the species P. omphalodes. On the other side, the original description of Paranoplocephala kirbyi Voge, 1948 shows some signs of the genus Anoplocephaloides

: "The uterus in early mature proglottids is composed of two narrow tubes the end of which project beyond the median excretory ducts; a small duct from the région of the shell gland connects the transverse tubes just anterior to the ovary. In more posterior mature segments the end of the uterine tubes become forked and the main tubes give off side branches. In gravid segments the sac-like uterus fills entire segment, and no other/structure but the excretory ducts remains." - See VOGE (1948), p. 302 and the figures 2, 3, p. 301. Only new material from U.S.A. can explaine more exactly the generic position of P. kirbyi. 14. Paranoplocephala ondatrae (Rausch, 1948) Tenora et Murai, 1980. Syn.: Andrya ondatrae Rausch, 1948, Aprostatandrya macrocephala (Douthitt, 1915) sensu Rausch et Schiller, 1959 pro parte, Aprostatandrya ondatrae (Rausch, 1948) Spassky, 1951. Original host: Ondatra.

zibethiçus. North America. Holotype: deposited in the Helminthological Collection of the U.S. National IV! useum. Comments: This species is a characteristic parasite of Pndajra_zibejhi^us. RAUSCH and SCHILLER (1849) consider it to be a synonym of the species A. macrocephala. The approach of SPASSKY, ROMANOVA and NAJDENO

VA (1951) was the same. RAUSCH and SCHILLER (1949), who consider P. ondatrae to be a synonym of A. macro cephala, on page 309 of their study report the following: "testes across entire field, over excretory canals on both sides, sometimes beyond aporal canal." However, on page 313, in Fig. 14 the same authors drew the testes only across the entire field, not over the excretory canals.
