  Theories where a fermionic dark matter candidate interacts with the Standard
Model through a vector mediator are often studied using minimal models, which
are not necessarily anomaly-free. In fact, minimal anomaly-free simplified
models are usually strongly constrained by either direct detection experiments
or collider searches for dilepton resonances. In this paper, we study the
phenomenology of models with a fermionic dark matter candidate that couples
axially to a leptophobic vector mediator. Canceling anomalies in these models
requires considerably enlarging their field content. For an example minimal
scenario we show that the additional fields lead to a potentially much richer
phenomenology than the one predicted by the original simplified model. In
particular collider searches for pair-produced neutralinos and charginos can be
more sensitive than traditional monojet searches in thermally motivated parts
of the parameter space where the mediator is outside the reach of current
searches.
