With the Ω-operators for the Virasoro algebra [5] and the super Virasoro algebra in [10,9], we get the Ω-operators for the Ovsienko-Roger superalgebras in this paper and then use it to classify all simple cuspidal modules for the Z-graded and 1 2 Z-graded Ovsienko-Roger superalgebras. By this result, we can easily classify all simple Harish-Chandra modules over some related Lie superalgebras, including the N = 1 BMS 3 algebra, the super W (2, 2), etc.
