Key to West Palaearctic Hoplocampa species (imagines)

Note: The male of cantoti is unknown. The male of brevis is extremely rare: we were unable to locate any specimens. Hoplocampa tadshikistanica is so far only known from the type series collected in Tadzhikistan, and is thus extra-limital, but is included because it might occur in the West Palaearctic. Hoplocampa sogdiana Zhelochovtsev, 1976 is not included, because no specimens were available for examination, and the original description is not very informative. It is also only known from the type series collected in Tadzhikistan, from Crataegus laevigata (Poir.) DC (= oxyacantha auct.) (Zhelochovtsev 1976).
