In both genders the abdomen is entirely black. A similar species to Euura caeruleocarpa but the hind tibial inner spur is 1.5 times the length of the apical breadth of the hind tibia. In the male the spur is clearly more than half the length of the basitarsus. Both genders are mostly black with brown on the labrum. The legs are largely yellowish-brown. The cerci are shorter than the sawsheath when viewed from above.
Larvae feed on birches, poplars, willows and broad-leaved dock.
