  We describe a general construction providing index theorems localizing the
Chern classes of the normal bundle of a subvariety inside a complex manifold.
As particular instances of our construction we recover both Lehmann-Suwa's
generalization of the classical Camacho-Sad index theorem for holomorphic
foliations and our index theorem for holomorphic maps with positive dimensional
fixed point set. Furthermore, we also obtain generalizations of recent index
theorems of Camacho-Movasati-Sad and Camacho-Lehmann for holomorphic foliations
transversal to a subvariety.
