133 Euura uda (Holmgren, 1883) Figs 122, 365 Nematus udus Holmgren, 1883: 147–148, pl. 3 fig. 14. Lectotype ♂, designated by Lindqvist (1967a), not found in NHRS. Type locality: Russia, Novaja Zemlya, Matotschkin Scharr or Besimannija Bay. Nematus (Pachynematus) acutiventris Hellén, 1948: 115–116. Lectotype designated below. Syn. nov. Pachynematus inopinatus Lindqvist, 1949: 82–83. Syn. nov. Diagnosis The most similar species is E. punctifrons, see discussion under that species. Female 5.0– 5.5 mm. Head black; labrum pale; clypeus black; supraclypeal area black; thorax black; pronotum black; tegula pale; pterostigma pale; metafemur mostly black (to mostly pale?); metatibia pale; hind tarsus pale (to black?); abdomen nearly completely black; valvula 3 black (always without dorsobasal pale area?); mesepisternum smooth or slightly matt; claws with small subapical tooth; valvula 3 in dorsal view narrow and apically acute. Type material examined Lectotype Nematus (Pachynematus) acutiventris, here designated FINLAND – Lapin Lääni • ♀; Kilpisjärvi, Pikku-Malla; 3 Jul. 1935; W. Hellén leg.; 69.05° N, 20.74° E; MZH, http://id.luomus.fi/GL.3560. Holotype Pachynematus inopinatus FINLAND – Lapin Lääni • ♀; Kilpisjärvi, Malla; 69.07° N, 20.69° E; 18 Jul. 1943; R. Frey leg.; MZH, http://id.luomus.fi/GL.3580. Notes Lancet as in E. uda, but claws with small subapical tooth as in E. punctifrons. Host plants Unknown. Genetics COI Based on 7 specimens, maximum within-species distance is 0.3% and the nearest neighbour, diverging by a minimum of 3.04%, is Euura connecta. Nuclear Based on 5 specimens, maximum within-species distance is 0.36% (0.22% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.99%, is Euura fuscomaculata. Distribution and material examined Palaearctic. Specimens studied are from Finland, and Sweden.
