BACKGROUND
The spider fauna of the Ogasawara Islands, oceanic islands located 1,000 km south of mainland Japan was comprehensively examined by the National Museum of Nature and Science in 2011, which revealed that approximately 70% of the spider fauna was composed of non-native species. Following the preceding study, however, only descriptions of several new species have been added and no major updates have been made for the overall spider fauna of the Islands.
NEW INFORMATION
The faunistic survey of spiders conducted on Chichi-jima Island, the largest island in the Ogasawara Islands in 2023 revealed the presence of two ground-dwelling spider species, Thorell, 1881 (Araneae, Liocranidae) and Lin & Li, 2022 (Araneae, Palpimanidae) on the Island. This represents the first record of the two species from Japan, the first record of palpimaid spiders from Japan and the initial documentation of liocranid spiders in the Ogasawara Islands.
背景
2011年，日本国立自然科学博物馆对位于日本本土以南1000公里处的海洋岛屿小笠原群岛的蜘蛛群落进行了全面调查，结果显示约70%的蜘蛛群落由非本地物种组成。然而，在之前的研究之后，仅新增了几种新物种的描述，该群岛蜘蛛群落的整体情况并无重大更新。
新信息
2023年在小笠原群岛最大的岛屿父岛进行的蜘蛛区系调查发现，岛上存在两种地栖蜘蛛物种，即1881年的托氏蛛（蜘蛛目，光盔蛛科）和2022年的林氏蛛（蜘蛛目，幽灵蛛科）。这是这两个物种在日本的首次记录，是幽灵蛛科蜘蛛在日本的首次记录，也是小笠原群岛光盔蛛科蜘蛛的首次记录。
