Stenoponia montana Darskaya has been reported in 1949 by Darskaya as a new species in the mountain forests of northern Korea. The present article deals with the records of the species from the mountain regions of central Japan, Nagano- and Kyoto- prefectures with systematic descriptions, host relations and some ecological notes. In winter, from end of October to February, the species is found on the bodies of several species of small rodents such as Apodemus speciosus, Ap. sylvaticus, Rattus rattus, Microtus montebelli and Eothenomys smithii and in one single instance on the Japanese yellow marten, Martes melampus. Eggs, before oviposition, are observed in the abdomens of four specimens of the species. The eggs are long ovoid and occur in pairs in the abdomens. The surface of the egg is uniformly covered by beautiful network consisting of smaller pentagonal and hexagonal cells. The micropylar openings on the anterior pole are found about 60 in number, whereas the posterior apparatus is found to consist of about 30 openings.
