A rather small, if robust, species, the body is a matted black, with a metallic bronze luster, while the deep-green thorax is conspicuously covered with small hairs. In males, the shape of their tail appendages is characteristic, with their outer contours appearing broken in two spots and the tips curving inward to give them a pincher-like appearance. The ovipositor valve of females appears triangular and strongly prominent from the side. Both sexes feature two veins on the forewings (whereas other species have only one). In our country, the Alpine Emerald has been sighted in the border mountains.
