Euura jugicola

186 Euura jugicola (Thomson, 1871) Figs 207, 431–432 Nematus jugicola Thomson, 1871: 146–147. Lectotype designated below. Pteronidea karvoneni Lindqvist, 1969: 237–238. Synonymy by Hellén (1976). Diagnosis Females are most similar to E. hypoxantha: see details under that species. The abdomen of living specimens can be extensively pink, and the mesepisternum is usually (always?) slightly matt. In North America, at least males can have a black pterostigma (yellow to brown in Europe). Penis valves are most similar to E. fuscodorsata and E. parvilabris (E. bipartita group). Legs and abdomen ventrally are extensively pale in E. jugicola but in E. parvilabris mostly black. Euura fuscodorsata is paler (e.g., mesepisternum pale, whereas black in E. jugicola) and the males seem to have a smaller subapical tooth of claws than in E. jugicola. In males, hind tarsi and tip of hind tibia from black to pale, in female (always?) largely pale. Type material examined Lectotype Nematus jugicola, here designated SWEDEN – Dalarna • ♀; Dalecarlia alpibus [mountainous part of Dalarna province]; C.H. Boheman leg.; NHRS, NHRS-HEVA000003972. Holotype Pteronidea karvoneni FINLAND – Lapin Lääni • ♀; Kilpisjärvi; 69.04° N, 20.81° E; 2 Jul. 1964; V.J. Karvonen leg.; MZH, http://id.luomus.fi/GL.3504. Host plants Salix spp., including S. glabra Scop. (Weiffenbach 1975), S. aurita L., S. myrsinifolia, and S. phylicifolia (Kangas 1985). Genetics COI Based on 10 specimens, maximum within-species distance is 4.1% and the nearest neighbours, diverging by a minimum of 5.32%, are Euura connecta and E. semiopaca. Nuclear Based on 7 specimens, maximum within-species distance is 0.3% (0.44% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.98%, is Euura myosotidis. Distribution and material examined Holarctic. Specimens studied are from Canada, Finland, Italy, Sweden, and the USA.
