  For a rank one Lie group G and a Zariski dense and geometrically finite
subgroup $\Gamma$ of G, we establish equidistribution of holonomy classes about
closed geodesics for the associated locally symmetric space. Our result is
given in a quantitative form for real hyperbolic geometrically finite manifolds
whose critical exponents are big enough. In the case when G=PSL(2, C), our
results can be interpreted as the equidistribution of eigenvalues of $\Gamma$
in the complex plane.
  When $\Gamma$ is a lattice, this result was proved by Sarnak and Wakayama in
1999.
