... looks too much dense and coarse. In this area there are other species with the same colouration, but with slightly different shape of the head: H. mediocrum and H. sculpturatum . Anyway, without the specimen in your hands ... it's impossible to add something else. Thanks Paolo

For me it is not rossicum (the valid name for valesiense, see the paper of Paolo Rosa), because rossicum has a gold-green metallic patch on the central sternite.
