Euura bohemani

169 Euura bohemani (Thomson, 1871) Figs 189, 418 Nematus bohemani Thomson, 1871: 143. Lectotype designated below. Pteronidea pseudonotabilis Enslin, 1916a: 417–418. Lectotype designated below. Synonymy by Lindqvist (1954). Pteronidea pseudonotabilis var. simplex Forsius, 1921: 28. Syntypes ♀♀ (MZH?), not examined. Type locality: southern Finland. Synonymy by Taeger et al. (2010). Pteronidea pseudonotabilis var. t-magnum Malaise, 1931b: 51. Lectotype designated below. Synonymy by Taeger et al. (2010). Pteronidea fuscinervis Lindqvist, 1959c: 54–56. Synonymy by Hellén (1976). 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.

Genetics COI Based on four specimens, maximum within-species distance is 0.3% and the nearest neighbour, diverging by a minimum of 1.82%, is Euura ferruginea. Nuclear Only one sequence is available. The nearest neighbour, diverging by a minimum of 0.83%, is Euura ferruginea. Distribution and material examined Palaearctic. Specimens studied are from Estonia, Finland, Russia, and Sweden.
