First records of Osteochilus flavicauda Kottelat & Tan, 2009 (Cypriniformes, Cyprinidae, Labeoninae) from Indonesia

Two specimens of Osteochilus flavicauda were found in 2023 from Bangka Island and Belitung Island, within the Bangka‑Belitung Islands Province, Indonesian Archipelago. These specimens represent the first record of the species from Indonesian islands and the country. These new records extend the known geographic range to the southeast, beyond the mainland sites of Johor, Malaysia, and Pattani, Thailand. These findings represent a significant range extension and contribute to the understanding of the ichthyo‑ fauna in undersampled regions of Sundaland.
