Euura schlueteri

225 Euura schlueteri (Enslin, 1915) Figs 243, 463 Amauronematus schlueteri Enslin, 1915: 405–406. Lectotype designated by Schmidt (1997). Amauronematus lundbohmi Malaise, 1921b: 119–120. Lectotype designated below. Synonymy by Lindqvist (1941b). Amauronematus uliginosae Malaise, 1921b: 122–123. Lectotype designated below. Synonymy by Lindqvist (1941b). Amauronematus squamosus Lindqvist, 1959d: 14. Holotype ♀ (http://id.luomus.fi/GL.2775, MZH), not examined. Type locality: Finland, Utsjoki Outakoski. Synonymy by Benson (1962). Diagnosis Its characteristically short valvula 3 is the best morphological character for recognizing E. schlueteri, but this distinction is not always clear with respect to the other species with similar colouration (particularly E. striata). The unusual host (Vaccinium) for the Euura histrio group and nuclear data additionally support the distinctness of the species. Males might not be clearly distinguishable from most of the other species. Type material examined Lectotype Amauronematus schlueteri SWEDEN – Lule Lappmark • ♀; Njunjes; 66.96° N, 17.45° E; 30 Jun. 1914; Schlüter leg.; ZSM, GBIF-GISHym3056. Lectotype Amauronematus lundbohmi, here designated SWEDEN – Torne Lappmark • ♀; Torneträsk; 68.22° N, 19.74° E; 400 m a.s.l.; R. Malaise leg.; NHRS, NHRS-HEVA000003924. Notes Sawsheath about 0.9–1.0 times as long as hind femur with trochantellus in the lectotype. Lectotype Amauronematus uliginosae, here designated SWEDEN – Uppland • ♀; Resarö; 59.42° N, 18.35° E; R. Malaise leg.; NHRS, NHRS-HEVA000003929. Notes Sawsheath of lectotype about 0.8–0.9 times as long as hind femur with trochantellus. Host plants Vaccinium myrtillus, V. uliginosum (Schmidt 1997). Genetics COI Based on 10 specimens, maximum within-species distance is 0.76% and the nearest neighbours, diverging by a minimum of 0%, are Euura rufa, E. striata, E. stordalensis, E. hartigi, and E. histrio. Nuclear Based on 8 specimens, maximum within-species distance is 0.28% (0.3% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.37%, is Euura striata. Distribution and material examined Palaearctic. Specimens studied are from Finland, and Sweden.
