Males and females may present different identification difficulty in spiders. These identification ratings are based on the most difficult identification. New species may become recognised or become part of the British fauna e.g. from Europe, so identification should be made with the awareness that this is a possibility and that confirmation may be needed in the form of a voucher specimen.
