It is a female Sicus ferrugineus. There is a second (very rare) British species - abdominalis - but it has a shorter second abdominal segment, and much larger theca (the ventral projection on segment 5). There's other species on mainland Europe which perhaps we should be looking out for as well. I've no idea how to tell the males apart!
