I do not have the key (yet). I just looked into the British Flies. On page 674 till 677 you`ll find the description of both species.
My thought that the specimen may belong to H. cingulata just came by the fact that COllin mentions of albiventris that the first five abdominal segments are whitish yellow, while cingulata has just the basis of the abdomen paler, while sometimes all pale, except hypogonium.
Looking at the photo I see that only the first segments are pale, while the remaining are just ventrally pale.
