mName = this.href.substring(
    this.href.lastIndexOf('/') + 1
);

You can simply use this.href, the jQuery objects are not needed.

Instead of extracting the value out of the URL you could set a data attribute to store the name.

For example:

HTML

<area shape="poly" data-name="Bayern" href="/kosmetikstudios/deutschland/Bayern" />
<area shape="poly" data-name="Berlin" href="/kosmetikstudios/deutschland/Berlin" />

JS

<script type="text/javascript">
  $(document).ready(function(){
  var mName="passiv";
    $("#map area").mouseenter(function(){

      //read the data attributes
      mName = $(this).data("name");

      bName="images/" +mName + ".png";
      $("#map img").attr("src", bName);

    });

    $("#map area").mouseleave(function(){
      bName="images/Europa.png";
      $("#map img").attr("src",bName);

    });

  });
</script>

You can do this:

mName = $(this).attr("href").split("/").reverse()[0];

Consider this.href.split("/").reverse()[0];

Yes ofc, native JS is better.
