Euura lichtwardti

143 Euura lichtwardti (Konow, 1903) Figs 143, 380 Nematus apicalis Hartig, 1837: 201. Lectotype designated by Haris (1997). Synonymy by Lindqvist (1955). Primary homonym of Nematus apicalis Stephens, 1835 [Dineura stilata (Klug, 1816)]. Pachynematus lichtwardti Konow, 1903a: 379 (key). Lectotype designated below. Pachynematus kubesi Konow, 1905a: 154. Lectotype designated below. Synonymy by Lacourt (1999). Diagnosis Females are most similar to E. moerens. Metatarsomere 1 and metafemur are usually completely or nearly completely black in E. lichtwardti, but usually extensively pale (basal third of metatarsomere 1) in E. moerens. In males, tergum 8 has a distinct apical projection that distinguishes it clearly from E. moerens (absent or indistinct). The penis valves are also distinct from those in E. moerens and the other Euura. In males, sometimes terga 5–8 laterally and laterodorsally pale. Type material examined Lectotype Nematus apicalis GERMANY [according to the title of Hartig 1837] • ♀; ZSM, GBIF-GISHym3196. Lectotype Pachynematus lichtwardti, here designated CZECH REPUBLIC – Sudeten • ♀; Altvater; 50.08° N, 17.21° E; 12 Jun. 1900; B. Lichtwardt leg.; SDEI, GBIF-GISHym3872. Lectotype Pachynematus kubesi, here designated CZECH REPUBLIC – Central Bohemia • ♀; Kolin; 50.03° N, 15.20° E; A. Kubes leg.; SDEI, GBIFGISHym3873. Host plants Elytrigia repens (L.) Gould. (Kontuniemi 1965), Calamagrostis spp. (Kangas 1985; Macek et al. 2020). Genetics COI Based on 4 specimens, maximum within-species distance is 4.06% and the nearest neighbour, diverging by a minimum of 4.26%, is Euura moerens. Nuclear Based on 2 specimens, maximum within-species distance is 0.06% (0.03% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 1.47%, is Euura clitellata cluster 5. Based on 3 specimens of NaK (1654 bp), maximum within-species distance is 0.12% (also 0.12% when considering haplotypes of ZMUO.032405). Distribution and material examined Palaearctic. Specimens studied are from Czech Republic, Finland, Germany, Norway, Sweden, and the United Kingdom.
