(Lagomorpha) in Norway" - Tenora, F. .- Murai, É. - Berg, C.Parasit. Hung. 12. 53-54. 1979. ABSTRACT. New findings of the species M. pectinata from L. timidus in Norway are reported. The authors redescribed the material from Norway. It is stated that the material of the species M. pectinata from Norway is similar (as to the number of testes and the size of eggs) to the material of the same species parasiting in Lagomorpha in America. When studying the helminthofauna of Lepus timidus in Norway a series of tapeworms of the species M. pectinata was obtained. Regarding the fact that the material of the species M. pectinata differed in some traits (above all in numbers of testes and in the size of eggs) from the description of European material the results obtained are presented in the following text. Results Mosgovoyia pectinata (Goeze, 1782) Host species: Lepus timidus L. - Localization: small intestine. - Localities: Malmöya, Isl. in south-eastern Norway (M 2, M 4, M 14, M 16, M 17), Tranöya, Isl. in northern Norway (T 7). Description: compiled on the base of ten fully gravid specimens. Strobile 180-230 mm long, maximum width 10-llmm. Scolex relatively small (0.280-0. 300 mm in diameter), provided with four suckers (Fig. la). Suckers 0.150-0. 185 mm in diameter. The strobile of fully gravid tapeworms has a neck of the size of 0.500-0. 600 mm; behind it there are, in average, 20 segments without the sexual apparatus. The number of juvenile segments is about 60 and those of mature and postmature segments about 80. There are about 100 of fully gravid segments and the last 50 are filled with ripe eggs. Genital organs are paired. Testes 130-160 in number, situated in the posterior part of proglottids, posteriorly to uterus, filling the middle field and the poral part from ovary to longitudinal canals (Fig. lb). The cirrus pouch long (0.800 to 1. 100 mm), the cirrus (0. 680 mm long) with fine spines. No typical external seminal vesicle is developed. Vagina is very long, always crossing longitudinal canals with small glands on the inner side (Fig. lb). Uterus in lateral parts of segments is always situated posteriorly to ducts of genital organs, not crossing longitudinal excretory canals. Uterus is like a transverse tube, developing anterior and posterior sacculations. Eggs measure 0.080-0.100 mm, pyriform apparatus well developed (0.037 x 0.020 mm), hooks of embryons 0.010 mm. A note: SPASSKY (1951) mentioned that the species M. pectinata is parasitic in a number of mammalian species from the order Lagomorpha in the Holarctic region, among other countries also in Norway. TENORA and MURAI (1978) pointed out that the taxonomic status of the species of the genus Mosgovoyia Spassky, 1951 had not been yet satisfactorily cleared. As far as the species M. pectinata is concerned, SPASSKY (1951) distinguished two
