Abstract: 177 Euura nigricornis (Serville, 1823) Figs 196, 424 Nematus nigricornis Serville, 1823: 65. Syntypes ♀ ♂, not located in MNHN. Type locality: France, Paris area. Nematus zetterstedti Dahlbom, 1835a: 40, plate fig. 5. Syntypes ♀♀ (ZMLU), not examined [but examined by Lindqvist (1956)]. Type locality: not stated. Synonymy with miniatus by Thomson (1863). Nematus miniatus Hartig, 1837: 189–190. Lectotype designated below. Synonymy by Konow (1903c). Nematus sibiricus Jakowlew, 1888: 368–369. Synonymy by Konow (1903c). Nematus biannulatus Costa, 1890: 5, pl. III fig. 2. Holotype ♀, not located. Type locality: Greece. Synonymy by Konow (1903c). Diagnosis Black antennae and mesepisternum distinguish the females from the darker specimens of E. miliaris. Male not known for certain. Type material examined Lectotype Nematus miniatus, here designated GERMANY – Niedersachsen • ♀; Harz; 51.8° N, 10.3° E; W. Saxesen leg.; NFVG, GBIF-GISHym4677. Holotype Nematus sibiricus RUSSIA – Irkutskaja oblast • ♀; Irkutsk; 52.29° N, 104.24° E; ZIN, DEI-GISHym30174. Host plants Populus tremula. Records from Salix (Georgiev et al. 2002) and Betula (Boevé 1990) need confirmation. Genetics COI Based on 6 specimens, maximum within-species distance is 2.28% and the nearest neighbour, diverging by a minimum of 3.65%, is Euura miliaris. Nuclear Only one sequence available, a female with haplotypes diverging by 0.01%. The nearest neighbour, diverging by a minimum of 1.7%, is Euura miliaris. Distribution and material examined Palaearctic. Specimens studied are from Belgium, Czech Republic (uncertain male), Finland, Germany, Russia, and Sweden.
