The 6.5 to 8 mm large rove beetle Paederidus ruficollis (family Staphylinidae) is one of two quite similar species of the genus in Germany. Its sister species P. rubrothoracicus is slightly larger (8 to 9.5 mm) and exhibits a dark blue metallic abdomen, whereas in P. ruficollis the abdomen is black with only a faint blue metallic shine. In Europe, four species are known. The stenotopic, psammophilous species ranges from North Africa over Europe to Asia Minor and Iran. The gregarious beetles can be found on sandy and gravelly edges of rivers and lakes, where they move swiftly in the sunshine. The beetles are predaceous and feed on other insects. In Germany, recent records are known from many Federal States with exception of the East. Paederidus ruficollis is not regarded as endangered. (CB)
