In the summers of 2006 and 2007 presumed bites of Cheiracanthium spiders triggered mass hysteria in Austria and some regions of Germany, including northern Saxonia. Here we report the first records of Cheiracanthium mildei L. Koch, 1864 from Saxony and new records of C. punctorium (Villers, 1789) from Saxony and Brandenburg. C. punctorium is probably a native species in southern Germany. It shows a moderate area expansion that could be driven by global warming. Further records in north-western Saxony are to be expected. By contrast, C. mildei has to be regarded an invasive alien species that has rapidly spread into Central Europe from the Mediterranean. Leipzig is the north-easternmost locality in Europe reached so far, a further 230 km away from Nuremberg, the leading edge in 2006. A number of records in different districts of Leipzig suggest that the species is already established in the town. We also report verified bites of both species. The mild to moderate symptoms are in accordance with recent literature reviews.
