The heteropterous fauna of the Amami Islands, the Ryukyus, southern Japan, has been poorly known up to the present. In this report, 76 pentatomomorphan species are recorded as the first part of the faunal studies on Heteroptera of theIslands. Of these, about 65% are regarded as the Oriental elements. Many of them seem to be "newcomers" to the Japanese fauna having spread their distributional ranges by expansion of tillage of such cultivated crops as rice, beans, melons, citruses, and so on (cf.TOMOKUNI, 1979,1981,1985). Notobitus meleagris is probably the latest invader of them, which seems accidentally transported from Formosa to the Ryukyus in the 1970's being accompanied with stocks of an edible bamboo (HASEGAWA, pers. comm.). Though the southern Palearctic elements are apparently inferior to the Oriental species in the pentatomomorphan fauna of the Islands, three of them, Sastragala scutellata, S.esakii and Rhopalus sapporensis, become slightly differentiated morphologically in this Islands from those of the Japan proper. This fact suggests the possibility that these species immigrated into the Japanese Archipelago when the Amami Islands were connected by land with Japan proper.
