Psomopoulou defined and studied the Invariant submanifolds of a manifold with $f(2\nu+3,-1)$-structure. In this paper $f_a(2\nu+3,-1)$ structure has been defined and submanifolds, of a manifold with such a structure have been studied. Some interesting results have been stated and proved in this paper.
