We give a classification of almost complex algebraic curvature tensors in spaces of signature (0, 4) and (2, 2) which are almost complex spacelike IP. We describe the components of these curvature tensors with respect to the decomposition of the space of all algebraic curvature tensors into irreducible SO(4)- (or SO(2, 2)-) representations.
