N2 - The Eastern Sand Darter, Ammocrypta pellucida (Agassiz, 1863), has undergone range-wide population declines as a result of anthropogenic disturbances. Within Illinois, the fish historically occurred throughout the Wabash River drainage and Ohio River, but its range was reduced to only the Embarras and Vermilion river basins, including the Middle Fork Vermilion River and North Fork Vermilion River sub-basins. We report the first occurrences of A. pellucida in the Salt Fork Vermilion River sub-basin, thus expanding the known range of this imperiled fish by nearly 50 river-kilometers. The distribution expansion might indicate improved physicochemical conditions in the Vermilion River basin.
