GEOGRAPHIC-DISTRIBUTION OF GONGYLONEMA-PULCHRUM AND GONGYLONEMA-MACROGUBERNACULUM FROM MACACA-FUSCATA IN JAPAN

After a first report on the gullet nematode, Gongylonema pulchrum Moli n, 1857, being found in the Japanese macaque, Macaca fuscata, in Kyush u, Japan, the geographic distribution of the parasite, a causative age nt of gongylonemiasis in cattle and man, was examined in 181 monkeys t ransferred to the Japan Monkey Centre from 23 sites in Japan, includin g Yaku-shima (Island). Yaku-shima is included in the World Natural Her itage List of the United Nations for its subtropical forests, which ha ve on unusual variety of plant and animal species. G. pulchrum was fou nd in M. fuscata yakui monkeys inhabiting Yaku-shima and M. fuscata fu scata monkeys inhabiting Honshu and an island near Honshu. G. macrogub ernaculum was found in M. fuscata yakui monkeys. Comparison of the two kinds of parasite specimens obtained from the variety M. fuscata yaku i confirmed that G. macrogubernaculum Lubimov, 1931 is a valid species . Thus, the finding of G. macrogubernoculum constitutes a record of a newly identified host, M. fuscota yakui, and shows that Yaku-shima, Ja pan, is a natural locality of G. macrogubernoculum.
