The Korean Archipelago consists of more than 3,348 islands, many of which have an intact biodiversity. Gageodo Island, which is the south-westernmost island in the Peninsula, is characterised by floristic and faunistic features that are distinct from those of the mainland, making it of biogeographical and ecological interest. However, due to the difficulties associated with surveying this Island, it remains under-investigated. In particular, the Island's coleopteran fauna remains poorly understood.
In this study, the authors surveyed Buprestidae (jewel beetles), Carabidae (ground beetles), Cerambycidae (longhorn beetles), Lucanidae (stag beetles) and Melyridae (soft-winged flower beetles) on Gageodo Island. Each species was identified and ecological notes were recorded. To update the coleopteran list for the Island, previous studies that examined samples from Gageodo Island were compiled and organised. As a result, 31 species and three families were recorded on the Island for the first time, for a total of 93 species within 16 families. Of these, the melyrid species, (Satô & Ohbayashi, 1968) is reported for the first time in the Korean Peninsula. This study contributes to understand the coleopteran fauna of the biogeographically important Island in Korea and will serve as a foundational piece for understanding the fauna of Gageodo.
朝鲜半岛由3348多个岛屿组成，其中许多岛屿拥有完整的生物多样性。加戈岛是该半岛最西南端的岛屿，其植物区系和动物区系特征与大陆不同，具有生物地理学和生态学研究价值。然而，由于对该岛进行调查存在困难，其研究仍不充分。特别是，该岛的鞘翅目动物群仍鲜为人知。
在本研究中，作者对加戈岛的吉丁虫科（吉丁甲）、步甲科（步甲）、天牛科（天牛）、锹甲科（锹甲）和扁甲科（软翅花萤）进行了调查。对每个物种进行了鉴定并记录了生态笔记。为更新该岛的鞘翅目名录，作者整理并组织了之前对加戈岛样本进行研究的文献。结果，该岛首次记录了31个物种和3个科，共计16个科93个物种。其中，扁甲科物种（佐藤和大林，1968年）是朝鲜半岛首次报道。本研究有助于了解韩国这个具有生物地理学重要意义岛屿的鞘翅目动物群，并将作为了解加戈岛动物群的基础资料。
