ANDRYA-APODEMI SP-N (CESTODA, ANOPLOCEPHALIDAE), A PARASITE OF APODEMUS-ARGENTEUS (RODENTIA, MURIDAE) FROM HOKKAIDO, JAPAN

Andrya apodemi sp. n. from the small intestine of small Japanese field mice, Apodemus argenteus, from Hokkaido, Japan is described. This is the first species of the genus Andrya Railliet, 1893 that has been fou nd in murid rodents in Asia. This new species can be distinguished fro m related species by total length of strobila, genital pores situated unilaterally, number of testes (48-76), distribution of testes, which are mostly situated in the antiporal half of proglottids and do not ex tend beyond the antiporal excretory canal, and the size of eggs. In ad dition, upon review of specimens of Paranoplocephala omphalodes (Herma nn, 1883) Luhe, 1910 of Ishimoto (1974) in Hokkaido, we identified the m as A. apodemi because of the network-like structure of the uterus in postmature proglottids.
