The parasitic nematodes of Apodemus speciosus [As: Abbreviation of host name] and A. argenteus [Aa] (Murinae: Muridae: Rodentia) collected on Yaku-shima I., Tanega-shima I., and Kuchinoerabu-jima I., southern part of Japan, were investigated. Total number of the mice examined is 38 individuals of As and 36 individuals of Aa collected on Yaku-shima I., 27 individuals of As and 5 individuals of Aa collected on Tanega-shima I., and 2 individuals of As collected on Kuchinoerabu-jima I., respectively. Nine nematode species were obtained from Yaku-shima I., viz., Heligmonoides speciosus [Hosts: As, Aa], Syphacia emileromani [Aa], Syphacia sp. [larval form] [Aa], Heterakis spumosa [As], Subulura (Murisubulura) suzukii [As], Rictularia cristata [As, Aa], Mastophorus muris [Aa], Rhabditis (Pelodera) orbitalis [3rd larva] [As], and Capillariidae gen. sp.[Aa]. On the other hand, 6 nematode species were obtained from Tanega-shima I., viz., H. speciosus [As, Aa], S. emilerornani [Aa], S. (M.) suzukii [As, Aa], R. cristata [As, Aa], M. muris [As, Aa] and Gongylonema (Gongylonema) neoplasticum [As], and only 1 species, H. speciosus, was obtained from Kuchinoerabu-jima I. [As]. There are several studies on the parasitic nematodes of the genus Apodemus of Kyushu and its surrounding offshore islands. However, this is the first report of the nematodes from Yaku-shima I., Tanega-shima I. and Kuchinoerabu-jima I.. These nematodes are common with those of mainlands of Japanese Islands although Ohsumi Is. are thought to have been isolated from Kyushu between 100,000 and 130,000 years ago.
