Diagnosis

Black pterostigma, lancet (radix shorter than lamnium, 19–20 serrulae), and colouration of the abdomen (mostly yellowish or reddish with narrowing medio-dorsal black line) distinguish the females from the other Euura . Similar is also Nematus umbratus , which has fewer serrulae (13–16(17?)) and a different colour pattern of the abdomen. Males might not always be distinguishable from those of E. melanocephalus if colouration of mesepisternum is not stable (black in E. bohemani , dorsally pale in E. melanocephalus ). It might not always be possible either to distinguish the males from those of E. cadderensis , E. ferruginea and E. kangasi , which can have a rather dark pterostigma.
