%X A <em>PT</em>-symmetric Hamiltonian associated with a trigonometric Razhavi potential is analyzed. Along the same lines of the general quasi-exactly solvable analytic method considered in the <a href=\"#ref1\">[1]</a> <a href=\"#ref2\">[2]</a><a href=\"#ref3\"> [3]</a>, three necessary and sufficient algebraic conditions for this Hamiltonian to have a finite-dimensional invariant vector space are established. This <em>PT</em>-symmetric 2 x 2 -matrix Hamiltonian is called <em>quasi-exactly</em> <em>solvable</em> (<em>QES</em>).
