Query: Thermal Leptophilic Light Vector Dark Matter with Spinor Mediator and
  Muon (g-2) Anomaly   Inspired by the recently new measurement of $(g-2)_{\mu}$ at FermiLab and
reported upper bound for electron-dark matter (DM) recoil by the XENON1T
collaboration, we revisited phenomenology of a light MeV scale vector dark
matter in a leptophilic extension of standard model while a new spinor field
plays the role of mediator. A viable parameter space is considered to discuss
the possibility of light dark matter relic density as well as anomalous
magnetic moment of the muon. We study DM-electron direct detection and
cosmological bounds on the parameters space of the model. It is shown that
although new bound of $(g-2)_{\mu}$ anomaly greatly confines the parametric
space of the model, the thermal light dark matter can exist for $\rm M_{DM}\sim
10^{-3}-10^{-1}~\rm GeV$.
