Abstract: The status of the bagrid catfish Mystus wolffii Bleeker, 1851 as a non-native species in Singapore is reassessed in this study. Evidence is presented here to suggest that Mystus wolffii is native to Singapore. The taxonomic status of Mystus armiger, here considered a junior subjective synonym of Mystus wolffii, is also clarified in this study.
