                         polar. We performed optical spectroscopic, polarimetric and 
                         photometric follow-up of this variable source identified by the 
                         Catalina Real Time Transient Survey. Using the mid-eclipse times, 
                         we estimated an orbital period of 3.787 h, which is above the 
                         orbital period gap of the cataclysmic variables (CVs). There are 
                         nine other known polars with longer orbital periods, and only two 
                         of them are eclipsing. We identified high- and low-brightness 
                         states and high polarization modulated with the orbital period. 
                         The spectra are typical of polars, with strong high ionization 
                         emission lines and inverted Balmer decrement. The He II 4686  
                         line is as strong as H \β. We modelled the photometric and 
                         polarimetric bright-state light curves using the CYCLOPS code. Our 
                         modelling suggests an extended emitting region on the white dwarf 
                         (WD) surface, with a mean temperature of 9 keV and B in the range 
                         18-33, although the possibility that it could be a two-pole 
                         accretor cannot yet be ruled out. TheWDmass estimated from the 
                         shock temperature is 0.67 M\⊙. The derived parameters are 
                         consistent with the eclipse profile. The distance was estimated as 
                         406  54 pc using the period-luminosity-colours method. MLS110213 
                         populates a rare sub-group of polars, near the upper limit of the 
                         period distribution, important to understand the evolution of
