- <p><b>170</b> <i>Euura cadderensis</i> (Cameron, 1875)</p><p>Figs 190, 419</p><p><i>Nematus cadderensis</i> Cameron, 1875: 127–129. Syntypes ♀♀ ♂♂ (BMNH?), not examined. Type locality: United Kingdom, Scotland; Glasgow area, Rannoch and Kingussie. Both <i>Salix cinerea</i> and <i>Betula</i> are mentioned as host plants.</p><p><i>Amauronematus moricei</i> Konow, 1902a: 388–389. Lectotype designated below. <b>Syn. nov.</b></p><p><i>Pteronidea macroserrata</i> Lindqvist, 1943: 105–107. Lectotype designated below. Synonymy by Lindqvist (1960c).</p><p><i>Pteronidea nuortevai</i> Lindqvist, 1958: 96–97. <b>Syn. nov.</b></p><p><b>Diagnosis</b></p><p>Possibly not morphologically distinguishable from <i>E. ferruginea</i>. Serrulae may be more protruding in <i>E. cadderensis</i> than in <i>E. ferruginea</i>, although variability at least within <i>E. ferruginea</i> can make the difference weak to non-existent. <i>Euura kangasi</i> is also very similar, but may have black hind tarsi which seem to be paler in <i>E. cadderensis</i> and <i>E. ferruginea</i>. <i>Euura ferruginea</i> can be rather dark (abdomen dorsally and thorax completely or nearly completely black) which might not be the case for <i>E. cadderensis</i> females. Based on the host (<i>Betula</i>) and nuclear data, we keep <i>E. cadderensis</i> as a distinct species.</p><p>The lectotype of <i>Pteronidea macroserrata</i> is also the lectotype of <i>Amauronematus moricei</i>. Lindqvist (1943) examined this specimen as well as a second syntype of <i>A. moricei</i> and determined the second syntype (not located by us), as <i>Pteronidea ferruginea</i>, with which <i>Amauronematus moricei</i> has previously mostly been synonymised.</p><p><b>Type material examined</b></p><p><b>Lectotype <i>Amauronematus moricei</i></b>, here designated</p><p>GERMANY – <b>Brandenburg</b> • ♀; Finkenkrug; 52.56° N, 13.03° E; 30 m a.s.l.; SDEI, GBIF-GISHym4745.</p><p><b>Lectotype <i>Pteronidea macroserrata</i></b>, here designated</p><p>GERMANY – <b>Brandenburg</b> • ♀; Finkenkrug; 52.56° N, 13.03° E; 30 m a.s.l.; SDEI, GBIF-GISHym4745.</p><p><b>Notes</b></p><p>The lectotype of <i>Amauronematus moricei</i> and <i>Pteronidea macroserrata</i> is the same specimen, making these names objective synonyms. Two paralectotypes of <i>Pteronidea macroserrata</i> (Finland, Nurmes, MZH?), were not examined. They were reared from larvae on <i>Betula</i> (Lindqvist 1943).</p><p><b>Holotype <i>Pteronidea nuortevai</i></b></p><p>FINLAND – <b>Häme</b> • ♀; Vuohiniemi; 60.95° N, 24.13° E; 29 Jul. 1948; P. Nuorteva leg.; MZH, http://id.luomus.fi/GL.3440.</p><p><b>Notes</b></p><p>Completely pale and with prominent serrulae.</p><p><b>Host plants</b></p><p><i>Betula pubescens</i>. According to some specialists only <i>Betula</i> spp., but others state that <i>Salix</i> spp. are host plants (e.g., Kontuniemi 1960; Kangas 1985).</p><p><b>Genetics</b></p><p><b>COI</b></p><p>Based on 5 specimens, maximum within-species distance is 0.46% and the nearest neighbours, diverging by a minimum of 0%, are <i>Euura ferruginea</i> and <i>E. kangasi</i>.</p><p><b>Nuclear</b></p><p>Based on 5 specimens, maximum within-species distance is 0.26% (0.44% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.27%, is <i>Euura ferruginea</i>.</p><p><b>Distribution and material examined</b></p><p>Palaearctic. Specimens studied are from Finland, and Germany.</p>
