Record of Gymnogobius petschiliensis (Gobiidae) from Shodo Island, Kagawa Prefecture, Japan

Oshima (1977) reported “Ukigori” from Shodo Island, Kagawa Prefecture, Japan. At that time, “Ukigori” included several species, such as Gymnogobius urotaenia, Gymnogobius petschiliensis, and Gymnogobius gymnogobius, making it unclear which specific species was referenced in the original report. Our in-vestigation in Shodo Island resulted in the collection of a single specimen of G. petschiliensis in September 2024, providing the first definitive record of this species from the location.
