Euura notabilis

281 Euura notabilis (Konow, 1903) Figs 295, 516–517 Pteronus notabilis Konow, 1903b: 307 (key). Lectotype designated below. Nematus pulcher Vikberg, 1982: 63. Unnecessary replacement name for Pteronus notabilis Konow, 1903. Diagnosis Colouration (extensively yellow abdomen, brown pterostigma, black head and thorax), more or less triangular valvula 3 in dorsal view, lancet, and penis valve distinguishes the species from the other Euura. Species with a similar lancet (16–18 serrulae, apical ones hook-shaped) are darker (e.g., E. declinata and the other species of the group). Euura scotonota has a somewhat similar lancet and pale underside of abdomen, but serrulae are less protruding, setae of the lancet are perhaps longer, and the pale colour is more whitish than yellowish compared to E. notabilis. Species with similar penis valve (1.5 mm, elongate, paravalva without distinct spines and ventroapically not distinctly protruding, valvispina long, straight and not distinctly expanded at base, ventroapical margin of paravalva narrow and more or less perpendicular to valvispina, invagination between valvispina and ventroapical margin of paravalva small or absent, connection between dorsal margins of valvura and valviceps without distinct bend) are distinctly darker (e.g., E. nigerrima, E. hyperborea, E. uda) or have an “ Amauronematus - type ” head. Euura putoni males seem to have a darker abdomen (dorsally nearly completely black), but otherwise might not be distinguishable from the males of E. notabilis (abdomen dorsally partly pale). Female Head black; labrum pale; clypeus black to partly pale; supraclypeal area black; thorax black; pronotum and tegula pale; pterostigma pale (yellow or brown); metafemur pale; metatibia pale with black apex; hind tarsus black; abdomen dorsally nearly completely pale to (completely?) black, ventrally pale; valvula 3 mostly black or basally extensively pale; mesepisternum smooth or slightly matt; valvula 3 in dorsal view gradually narrowing to an acute or slightly blunt tip. Type material examined Lectotype Pteronus notabilis, here designated POLAND • ♂; Breslau [Wroclaw]; 51.11° N, 17.03° E; SDEI, GBIF-GISHym3862. Host plants Bistorta officinalis. Genetics COI Based on 2 specimens, maximum within-species distance is 1.37% and the nearest neighbour, diverging by a minimum of 2.58%, is Euura putoni. When including also secondary intraindividual COI variants, maximum within-species distance is 4.86% and the nearest neighbour, diverging by a minimum of 1.83%, is an unidentified Euura vicina group larva (DEI-GISHym80076) from Primorsky Krai, Russia. Nuclear Based on 2 specimens, maximum within-species distance is 0.17% (0.1% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.4%, is Euura vicina group larva (DEI-GISHym80076) from Primorsky Krai, Russia. Distribution and material examined Palaearctic. Specimens studied are from Bulgaria, Estonia, Germany, Poland, and Russia.
