Geographical distribution of an endangered butterfly species, Shijimiaeoides divinus was analyzed three insect databases, ‘Database on Collection Records of Shijimiaeoides divinus’ , ‘Database on Literature List of Shijimiaeoides divinus’ and ‘Database on Collection Records of Insect at Nagano Prefecture’. There are five subspecies of this butterfly, S. divinus barine and S. divinus asonis in Japan, and S. divinus divinus, S. divinus asahii and S. divinus shinichiroi in foreign country. Recent records in 21st century are only at three points in foreign countries. Analyzing the database, subspecies S. divinus barine in Nagano Prefecture disappeared rapidly after 1980. Only two populations remained. Natural population of S. divinus barine is on the verge of extinction in Japan.
