A corallanid isopod in the manca stage (lacking pereopod 7), collected from alluvial gravel along the Batui River in Sulawesi, Indonesia, and identified questionably as Tachaea lacustris Weber, 1892, is illustrated and described in detail. Tachaea lacustris was known previously only from freshwater lakes in Sumatra and Java. Its presence in river alluvial gravel should not be interpreted as possible adaptation to the hyporheic habitat.
