289 Euura nitidipleuris (Malaise, 1931)Figs 299, 521Amauronematus nitidipleuris Malaise, 1931b: 45. Lectotype designated below.Amauronematus temporalis Hellén, 1970: 34. Syn. nov.DiagnosisApically extensively pale abdomen but black tegula and pronotum, short valvula 3, strongly curved lancet with 16–18 annuli, and size (6.0–8.0 mm) should enable identification of the female. Male has pale sternum 9, black tegula and pronotum, and unique penis valve (1.5 mm, small valvispina, paravalva basally and apically similarly broad, broad apex of pseudoceps, small invagination between valvispina and broad and round lobe of paravalva). Penis valves of E. acuminalis and E. annulata are similar, but in addition to some differences in the shape of the paravalva (more elongate or basally narrower than apically), males of these species are extensively pale. When he compared Amauronematus temporalis with nitidipleuris, Hellén (1970) relied on Lindqvist (1945), who apparently misinterpreted nitidipleuris. According to Lindqvist’s drawing (1945: fig. 4), nitidipleuris has a straight lancet, but at least the lectotype has a curved lancet, as in the type of temporalis.The COI sequence (458 bp) of the studied male (http://id.luomus.fi/GP.110187) is identical to a 130 bp fragment from the holotype of temporalis, and matches the sequenced larva rather well (1.09% different) and differs clearly from the other species by a minimum of 6.55%.Type material examinedLectotype Amauronematus nitidipleuris, here designatedRUSSIA – Kamchatka oblast • &female;; Klutchi [Klyuchi]; 56.32° N, 160.85° E; R. Malaise leg.; NHRS, NHRS-HEVA000006358.Holotype Amauronematus temporalisFINLAND – South Ostrobothnia • &female;; Alavus; 19 May 1937; A. Saarinen leg.; MZH, http://id.luomus. fi/GL.2476.Host plantsUnknown, but probably Salix like the other species in the group. Lindqvist (1953) reported two reared specimens from Salix (mentioned also by Kontuniemi 1960), but because he had apparently misinterpreted nitidipleuris earlier (Lindqvist 1945), the specimens might represent a different species in the group. The larva sequenced here was swept from a mixture of Salix and Betula nana.GeneticsCOIOnly one sequence (1087 bp) available, from a larva. The nearest neighbour, diverging by a minimum of 5.78%, is Euura viduata.NuclearOnly one sequence available, from a larva with haplotypes diverging by 0.21%. The nearest neighbour, diverging by a minimum of 1.15%, is Euura erecta (ZMUO.063230).Distribution and material examinedPalaearctic. Specimens studied are from Finland, and Russia.
