  We perform a comprehensive dark matter analysis of left-right supersymmetric
scenarios that includes constraints from dark matter direct and indirect
detection experiments and that presents distinctive features from those
available in minimal supersymmetry. We concentrate on dark matter candidates
which, while satisfying all constraints, are different from those of the
minimal supersymmetric standard model. We consider in our analysis all possible
co-annihilation channels relevant for setups in which several states are light
and nearly degenerate, and devise a set of representative benchmark points,
requiring co-annihilations, which satisfy all restrictions. We then study their
consequent LHC signals, which exhibit promising new multileptonic signatures
involving $W_R$, that if observed, would provide a strong support for
left-right supersymmetry.
