Euura itelmena (Malaise, 1931) Figures 7, 16E–F, 21D Pontopristia itelmena Malaise, 1931: 54. Described: syntypes, 2♀. Published type locality: Klutchi [Russia, Kamchatka]. Lectotype designated below. Amauronematus itelmena : Benson 1962; record from Canada. Euura itelmena : Sundukov 2017. Diagnosis. Female. Profile of valvulae 3 in dorsal view barrel-like (Fig. 7F): widened towards about the middle, then gently narrowing to the tip. In other species, the valvulae 3 widen to a point near their tip, or are subparallel. The dark fore wing costa and stigma distinguish E. itelmena from other amentorum group species, apart from E. freyja and E. pohjola n. sp. Description. Female (Fig. 7A–B). Body length 3.0–4.0 mm (lectotype 4.00 mm, European specimens 3.00– 3.80 mm). Black. Pale are only more or less mandibles, fore and mid tibia, base and underside of rear tibia, extreme apices of femora, fore and mid tarsi. Cerci infuscate. Wing veins including fore wing costa and pterostigma dark [apparently faded in lectotype]. Head. In dorsal view moderately contracted behind eyes, and length posterior of eye about 0.3–0.5 × length of eye (Fig. 7D–E). Mostly dull with coriaceous sculpture except for labrum. Upper head densely setose; setae pale, about 0.5 × as long as anterior ocellus diameter. Clypeus truncate to slightly emarginate medially. Labrum apically rounded. Antenna 0.94–1.10 × as long as fore wing costa. Thorax. Pronotum, mesoscutum and tegula densely punctate with small shiny interspaces; vestiture similar to upper head, adpressed. Lateral mesoscutal lobe approximately 1.5 × as long as greatest width. Mesoscutellum as broad as long, without longitudinal median furrow; finely sculptured and dull, but with only a few weak pits. Mesepisternum unsculptured, shiny, with nearly uniform covering of setae, about 0.6 × as long as diameter of anterior ocellus. Abdomen. Valvulae 3 (Fig. 7G) in lateral view clearly orientated upwards; tapering to the narrowly rounded tip. In dorsal view with a barrel-like profile: widened ...
