A large Ectemnius closely resembling the common E. continuus, but considerably scarcer. Formerly known under the names zonatus (Panzer, 1797), saundersi (Perkins, R.C.L., 1899) and quadricinctus (misidentification). The last name was also shared with E. cephalotes, making some old records impossible to assign.
Sparsely recorded throughout England an d Wales, extending as far north as the Whitby area of North-east Yorkshire. No clear northern or southern bias is apparent, though it appears to have increased its presence in northern England over recent decades, whilst declining in counties such as Dorset. Unrecorded in Ireland, and no records for the Channel Islands since 1958. Found in central and southern Europe, and through Siberia to China.
